Unit Start Up Procedure

Upon completing each step of the Installation Guide, keep the unit powered off, then follow these steps to start using the system:

1. Power Up: Switch the Unit to On – the Inverter On light should illuminate.
2. Supply power to an appliance(s) that is supported by the backup system to ensure that the appliance will run on battery power. Note: If you are powering a refrigerator or freezer, make sure to test it long enough to see that the appliance’s compressor turns on, you can speed up this process by opening the door of the appliance.
3. Now apply line power to the Power System’s Input side by switching on the circuit breaker that feeds the unit’s input power.
4. Make sure the Mains on LED light illuminates. One of the charging LED lights should also illuminate, either bulk, absorption or float.

Maintenance Procedures

Operation:
During normal operation while the unit’s input is supplied with utility power, the mains LED light will be lit as well as the state of charge. If the unit is fully charged, float charge should be lit. The unit’s settings are all preset so the knob that sets the unit’s current limit is bypassed. The LCD display should indicate AC1; this is normal. If your unit’s display is not displaying this, please contact support.

Absorption:
When the unit is supplied power and switched to on, it is ready to use. The unit will switch over to battery power (inverting) whenever power is lost. When power is restored, the unit’s charger will automatically recharge its batteries and continue to pass power through to the appliances it is supporting. The following sequences are LED indications of how the system is operating:

• Inverting: This indicates there is no input power present, and the inverter is drawing from its batteries.
• Excess Overload: The equipment load is exceeding the unit’s regular output, reduce the equipment load.
• Overload: This indicates that the unit is overloaded due to either a short circuit on the output or the equipment load is too large for the system to support.
• Batteries are low : This indicates that the system batteries are low. If the unit is supporting a load, it will not be long before the batteries go dead.
• Batteries are dead : This indicates that the battery voltage had gone too low, and the inverter has switched off.
• Temperature warning: The unit’s internal temperature is reaching a critical level.
• Temperature overload: The unit has reached an internal temperature level that is too high, and the unit shut off.
• Battery voltage too high : The unit’s battery voltage is too high; be sure the correct batteries are being used and they are installed correctly.
• Erratic battery voltage: The unit shut down due to excess ripple voltages out of the battery.

FAQ

• What should I do if the unit’s LCD display does not indicate AC1 during normal operation?
  If your unit’s display is not displaying AC1 during normal operation, please contact support for assistance.

• How long should I test a refrigerator or freezer powered by the backup system?
  To ensure that the appliance’s compressor turns on, test the refrigerator or freezer for a sufficient duration. You can speed up this process by opening the door of the appliance.

• What should I do if the unit indicates an overload?
  If the unit indicates an overload, reduce the equipment load to ensure it does not exceed the unit’s regular output capacity.

• How do I determine if the batteries are low?
  If the unit indicates that the batteries are low and is supporting a load, it will not be long before the batteries go dead. Take appropriate action to recharge or replace the batteries.

Statement of Liability for Medical Environments

• When used within a surgical environment, do not use in the presence of flammable anesthetic mixtures with air oxygen or nitrous oxide.
• This battery backup power system is not intended to support life but rather to power surgical appliances needed in superficial surgical procedures or medical cold storage appliances. Its use is intended for the supply of emergency power to appliances which may be employed in non-life-threatening medical procedures.
• The wellbeing of the patient is entirely the responsibility of the physician administering the anesthesia and surgical procedure. It is imperative that it is understood that at no time should a patient remain unattended. At this writing the FDA has no classification for a general-purpose medical emergency power supply. This system is not a medical device.
• If life-supporting equipment is to be powered, such as anesthesia equipment, life-signs monitors, gas monitors etc., it is Medi-Products expectation that such devices also have their own built-in FDA approved appliance-specific independent power supply source and is maintained correctly. General room lighting and exit signs are also expected to have multiple independent energy sources.
• Appliances such as refrigerators and freezers and the contents being stored within them are the responsibility of the owner/operator to see that they are monitored, maintained, and tested. Consequential damages and loss of perishable merchandise are not the liability of Medi-Products/Medicanix.
• It is the sole responsibility of the end user or equipment owner to ensure that the battery backup power system has been tested, maintained, and testing records have been kept and filed.

Unit Start Up Procedure

Upon completing each step of the Installation Guide, keep the unit powered off, then follow these steps to start using the system:

1. Power Up: Switch the Unit to “On” – the Inverter On light should illuminate.

2. Supply power to an appliance(s) that is supported by the backup system to ensure that the appliance will run on battery power.
   Note: If you are powering a refrigerator or freezer, make sure to test it long enough to see that the appliance’s compressor turns on, you can speed up this process by opening the door of the appliance.

3. Now apply line power to the Power System’s Input side by switching on the circuit breaker that feeds the unit’s input power.

4. Make sure the Mains on LED light illuminates. One of the charging LED lights should also illuminate, either “bulk”, “absorption” or “float”.

Maintenance Procedures

• The Medi-Products power system contains virtually no moving or lubricated components and, therefore, requires almost no user maintenance except testing and recordkeeping and periodically replacing the batteries (every 4 years).

• The user should be aware that by their nature, battery life is negatively affected by some usage patterns. Of course, batteries are intended to be used, but minimizing deep discharges, and frequent charge / discharge cycles will extend overall life. Their life expectancy will be generally in the range of four to five years. Please refer to the section on Battery Testing for more on this subject

• The system has a battery voltage alarm which will sound for below normal battery voltages. Battery voltage indicators should be checked if the alarm sounds. Often a low battery alarm will result from a tripped input supply breaker in the main building electric panel. If this is not the cause, please contact Medi-Products promptly.
  BY-PASS SWITCH

• Whenever the emergency power system is being serviced or not operational, move the bypass switch to “utility” mode to bypass the battery backup system.

Operation

• During normal operation while the unit’s input is supplied with utility power, the mains LED light will be lit as well as the state of charge. If the unit is fully charged, float charge should be lit. The unit’s settings are all preset so the knob that sets the unit’s current limit is bypassed. The LCD display should indicate “AC1” this is normal. If your unit’s display is not displaying this, please contact support.

• When the unit is supplied power and switched to “on” it is ready to use. The unit will switch over to battery power “Inverting” whenever power is lost. When power is restored the unit’s charger will automatically recharge its batteries and continue to pass power through to the appliances it is supporting.

• The following sequences are LED indications of how the system is operating:

Output Indicators

• Inverting: This indicates there is no input power present, and the inverter is drawing from its batteries:

• Excess Overload: The equipment load is exceeding the unit’s regular output, reduce the equipment load:

• Overload: This indicates that the unit is overloaded due to either a short circuit on the output or the equipment load is too large for the system to support:

• Batteries are low : This indicates that the system batteries are low. If the unit is supporting a load, it will not be long before the batteries go dead:

• Batteries are dead : This indicates that the battery voltage had gone too low, and the inverter has switched off.

• Temperature warning: The unit’s internal temperature is reaching a critical level.

• Temperature overload: The unit has reached an internal temperature level that is too high, and the unit shut off:

• Battery voltage too high : The unit’s battery voltage is too high; be sure the correct batteries are being used and they are installed correctly.

Battery voltage is too low for the inverter to recognize it.| Recharge the batteries with an external charger.
The Charger will not operate but the mains LED and the Bulk LED are lit.| The unit has been in bulk charge too long (over 10 hours)| Check the batteries and all the battery connections. Replace the batteries if they will not charge or will not hold a charge.

Qualified Technical Support & Procedures:

• Adjustments can be made to the inverter module. Please consult with technical service prior to making any adjustments, as unit should arrive with adjustments preset.
• A large amount of energy is stored in the batteries which can cause injury to unqualified persons attempting to effect repairs. Also, no one untrained regarding electrical energy should attempt any service task or remove any of the front covers as live circuits will be exposed in all cases.
• Eye protection should be worn by any person connecting or disconnecting batteries and battery cables.
• Hand & Eye Protection is recommended for any person handling batteries.

Testing Procedures

• Standards of testing the power system must be implemented and carried out along with regular testing.
• Medi-Products sets out the following guidelines and instructions that must be understood and implemented for the use and dependence on our battery backup generators.
• Weekly, Monthly and Annual load tests must be performed, recorded, and documented. The following criteria must be followed to complete each test:

Weekly Testing:

• The recommended weekly test is a quick and simple test which assures the functionality of the transfer switch, auto-invert, and charge mode.

• This test is performed by disconnecting the power that feeds the battery backup unit. Upon disconnecting the line power, your system should switch over to invert mode and draw its power from the batteries. At this point, you should be sure your equipment is still on and running.
  Note: If you need to find out your “runtime” contact tech support with your power system’s model and serial number and the make and model of the refrigerator or freezer you are supporting. If you are supporting operating room equipment the standard runtime is 2 hours.

• After you have ensured that your system has switched over and is inverting, you will need to restore the line power. This test should not last more than 2 to 3 minutes.

Monthly Testing:

• The monthly test is a load test that needs to be conducted no sooner than 20 days and no longer than 40 days from the prior (monthly) load test. This test is to ensure the generator can last 25% of its intended runtime. Your runtime is a pre-determined amount of time that your refrigerator will run on the battery backup. This would have been calculated at the time you purchased the unit.

• For the week you are performing the monthly test, it is not necessary to also perform the weekly test.
  Example: 12 hour run time = Monthly test 3 hours

• Another important issue is that it is possible to over-test your power system. Medi-Products battery backup system’s use of AGM batteries, which if they are discharged too frequently or discharged too deeply, it can cause damage to the batteries, shortening their life expectancy and weakening them.

• You may want to set a timer to remind you to restore the input power to the system and not over discharge the batteries. Reconnect the input power and recharge the battery bank. This may take several hours.

Record Keeping:
Recording these tests is important for the protection of your vaccines and costly inventory. You can use our test logs that are in our service manuals and can download from our website.

Battery Replacement

• Eye protection should be worn by any person connecting or disconnecting batteries and battery cables.

• The Batteries are to be replaced every 48 months. To order replacement batteries contact Medi-Products 800-765-3237

• It is better to have someone that is comfortable working with electrical appliances and/or batteries replace them. Often your Bio-Medical team, building maintenance or someone of that caliber is best suited to the job. Have them follow the following instructions for battery replacement:

  1. Disconnect the line power by switching off the input circuit breaker.
  2. 1200/2000watt systems: switch it to “Line Charge Only” 4000/4400/8800watt system: Turn the Red DC disconnect knob to the “off” position.
  3. Remove the front battery box covers to access the batteries – Take a photo of the battery connections or special note of how your batteries cables are configured so you can refer to it when reinstalling.
  4. Remove the battery cables:
  • 12 Volt Systems: Remove the entire positive cable set before removing any negative connections.
  • 24- or 48-Volt Systems: Start by removing one of the jumper cables between the batteries.
    This will help prevent the cables from accidentally shorting out against the cabinet or each other.
  5. Remove the batteries from the cabinet and slide the new ones into place.
  6. Re-Install the cables. – Refer to the diagram below:
  7. Reinstall the Battery Box Covers.
  8. Follow the Start Up and Testing Procedures within this manual.
