BORMANN BMI1010 Inverter Instruction Manual

Introduction

To get the most out of your power inverter, proper installation is critical. Please read the installation and operating instructions in this manual carefully before installing and using your power inverter. Pay special attention to the CAUTION: statements in this manual.
CAUTION: statements identify conditions or practices which could result in damage to your power inverter or to other equipment.
The power source must provide between 10 and 15 volts DC and must be able to supply sufficient current to operate the load. As a rough guide line, divide the power consumption of the load (in watts) by 10 to obtain the current (in amperes) in the power source must deliver.

Example: Load is rated at 300 watts. Power source must be able to deliver: 300 divided by 10=30 amperes.

CAUTION: Rechargeable batteries and devices with rechargeable batteries may not be suitable for use with the power inverter. The rechargeable batteries, recharging transformer and/or the power inverter may be damaged when trying to recharge devices of 24 volts and higher. The power inverter will not operate from a 6 volt battery. Refer to the manufacturers specifications when using these devices.

Safety instructions

Installation of the inverter
For best operating results, the inverter should be placed on a flat surface, such as the floor or seat of the vehicle. The inverter should only be used in locations that meet the following requirements:
A) DRY – Keep away from water. Do not allow water to drip or splash on power inverter.
B) COOL – Ambient air temperature should be between 10 degrees and 30 degrees C. Do not place the inverter on or near a heating vent or any piece of equipment which is generating heat above room temperature. If avoidable, do not place the inverter in direct sunlight.
C) VENTILATED – Allow at least one inch of clearance around the power inverter for air flow. Do not place anything on or over the inverter during operation.
Make sure that the air is allowed to circulate freely around the unit.
D) SAFETY – Do not use the power inverter near flammable materials or in any location which may accumulate flammable fumes or gases, such as the battery compartment of your car, truck, RV, or boat. This product is not suitable for use while traveling using battery clamps. The length of the wire cables and battery clamps are not designed for this operation. If you wish to operate the inverter while moving, the power inverter May be permanently mounted and wired.

Operating instructions

Connecting to the power source
Your power inverter does not come equipped with battery cables which must be purchased separately. The proper gauge of the battery cables can only be properly determined when Calculating the length of the cables from the inverter to the battery. These cables may be purchased from any automotive, marine or home center. (See Fig. 1 and Fig. 2)

CAUTION: DO NOT USE WITH POSITIVE GROUND ELECTRONICAL SYSTEMS.
CAUTION: MAKE SURE THE POWER INVERTER IS OFF.

Figure 1: Loosen the caps on the terminals and slide the lugs between the cap and the base. Then tighten firmly.
Figure 2: Insert the inverter lighter plug (not available on all models) into car cigar lighter socket.

Rated versus actual use of equipment
Most electrical tools, appliances and audio/video equipment have a label indicating power consumption in amps or watts.
Add up the power consumption in those items you will be using simultaneously, keeping total below max. power of inverter.
If the power consumption is rated in amps, multiply by the AC volts 220-240 to determine the wattage. For example, a television rated at 0.9 amps will use 99 watts, well within the limits of what the power inverter can handle on a continuous basis. For more information regarding the typical wattage draws of many appliances, please refer to the table on the back of this manual.

Resistive loads, such as incandescent lights, are the easiest for the inverter to drive, though larger resistive loads, such as electric stoves or heaters, require more power than the power inverter can deliver continuously.
Inductive loads, such as TV’s and stereos (any device with a coil or a transformer in it) require more current to operate than a resistive load of the same power rating. Induction motors (motors without brushes), as well as some televisions, may require 2 to 6 times their power rating to start up.
This condition may require repeated “ON/OFF, ON/OFF” several times switching of the power switch on your power inverter in order to get them started. The most demanding are those that start under load, i.e. compressors and pumps. Since motor and television characteristics vary widely, only experimentation will determine if a specific load can be started and how long it can be run.
There are no standards for “surge power” partly because it can not be simply represented by a simple of single sample number. Though the 300w power inverter can provide power up to 600 watts for a short period, experimentation is the only method of determining whether it can handle the surges generated by a particular load.

IMPORTANT NOTE: The power inverter will not operate most appliance designed to produce heat, such as hair dryers, coffee makers, irons, heaters, and toasters. The current use of most of these exceeds rated power watts, far beyond the capacity of this unit.
The inverter may be used either while engine is running or turned off. However, the inverter may not operate while the engine is starting, since the battery voltage can drop substantially during cranking.
The power inverter draws less than 1.3 ampere from the battery when it is not supplying power to the load. In most cases, the power inverter may be left connected to the battery when it is not in use, since it draws so little current. If the vehicle will not be used for several days, disconnect the power inverter from the battery.

Low battery alarm
An alarm will sound when the voltage of the battery drops to 10.5volts. This indicates that the battery requires recharging. The user should stop operations at this time, since the power inverter will shut down automatically when battery voltage drops to 10.0 volts.
If the low battery alarm sounds when the battery is fully charged, follow the steps for correcting the lack of output power in the Trouble Shooting Guide. The alarm will sound when the inverter is overloaded, or if there is an excessive voltage drop between the battery and the inverter.

NOTE: The alarm may sound momentarily when the unit is being connected to, or disconnected from, the power source. This is normal and does not indicate any problem.

Battery operating time
The typical vehicle battery has a minimum operating time of 1 to 2 hours, depending on the current use of the load being driven. We recommend that the operator start the vehicle every hour to recharge the battery system. This will prevent unexpected shut downs of equipment and will ensure that there is always sufficient battery capacity to start the engine.

Your power inverter circuitry constantly monitors the following hazardous conditions:
A) Low Battery Voltage – This condition is not harmful to the inverter, but could damage the power source. An audible alarm is sounded when input voltage drops to 10.5 volts. The inverter shuts down when input voltage drops to 10.0 volts. When the condition is corrected (i.e. alternator charges battery). The unit may be restarted.
B) Short Circuit – Reverse polarity or short circuit condition of the load will usually result in opening of the short circuit protecting.
C) High Temperature – When the temperature of the internal heat sinks reaches 150 degrees F, the solid – state temperature sensor located in the power inverter will automatically shut down the unit. Once it is allowed to cool, it may be restarted.

Troubleshooting

Be sure the environmental temperature

| Turn Inverter power switch off and on until it powers your appliance.
Battery voltage is below 10 volts.| Repeat as necessary until appliance starts.
Equipment being operated draws too much

power

| Charge or replace battery.
Inverter in thermal shut down condition.| Reduce load to maximum watts.
Battery in poor condition. Have battery checked.| Inverter must cool down. Check for good ventilation. Make sure load is less than max. continuous power.
Replace battery
Low Voltage Alarm On Continuously| Insufficien power or large voltage drop.| Check condition of alligator clips. Clean or replace as necessary.
Low Output Voltage| Using average reading oltmeter.| Use true RMS reading meter.
Inverter is overloaded.| Reduce load to continuous watts to maintain regulation.
Input voltage below 11.0 volts.| Keep input voltage above 11.0 volts to maintain regulation.
Television Interference| Snow Picture is breaking up.| A) Locate the power inverter as far as possible om television, the antenna, and the antenna ables.

Adjust the orientation of the power inverter antenna cables, and the TV power cord to reduce interference.

C) Make sure that the antenna feeding the tele- vision provides an adequate (“snow free”) signal and that high quality, shielded antenna cable is used.

Buzz or Hum in Audio System if used.| The power supply in the device dose not adequately filter the modified sine wave produced by the power inverter| Use a sound system that uses that a higher quality power supply.

Disposal and recycling

Ecological information: waste electrical and electronic equipment are a special waste category, collection, storage, transport, treatment and recycling are important because they can avoid environmental pollution and are harmful to health.
Submitting waste electrical and electronic equipment to special collection centers makes the waste to be recycled properly and protecting the environment.
Do not forget! Each electric appliance that arrive at the landfill, the field, pollute the environment!
