1. GENERAL INFORMATION

1.1 FRONT FACE

1.2 ENVIRONMENTAL SPECIFICATIONS

1.3 ELECTRICAL INPUT AND OUTPUT SPECIFICATIONS

1.3.1 NETWORK INPUT

1.3.2 OUTPUT

1.3.3 SPECIFIC FEATURES AND TECHNICAL SPECIFICATIONS

The Power supply and the public address and voice alarm system must be powered by the same mains. In normal operating mode : The power supply equipment recharges then maintains on charge from the normal backup supply, and provides current to the voice alarm system lower than Imax a. In emergency operating mode : the total operating current is provided by the battery, including the current of the PA/VA amplifiers not exceeding `Imax b mains not present’ depending on the size of the battery.

1.3.4 AUTHORIZED BATTERIES

• Use Yuasa, Powersonic, ABT, Enersys, Effekta, Long brand batteries. If you would like to use another battery brand, please have them approved.

2. INSTALLATION OF YOUR EQUIPMENT

2.1 MOUNTING

Note : When installing the module in the rack, the protection rating must comply with fire safety standards EN 54-4/ A2: IP30.

2.2 BATTERIES

⚠ The battery temperature sensor must be placed as close to the battery as possible.

• Position the temperature sensor as close to the battery as possible.
• The connections and crimping should be given special care. · A battery fuse adds 1 to 2 m.

3. CONNECTION

3.1 CONNECTION DIAGRAM

Important : the openings provided in the cabinet must be used. Do not create additional openings as doing so may casue the device to malfunction and voids the warranty.

3.2 CONNECTION SPECIFICATIONS

4. COMMISSIONING

Connect the battery wires to the terminal strip, but do not connect the battery terminals.
After the electrical connections are made (mains, loads and batteries) :

1. Close the upstream mains circuit-breaker.
2. Check the load output voltage.
3. Connect the battery terminals.
   Your apparatus is in operation when the 3 LEDs are green.

5. POWER SUPPLY OPERATION

5.1 ALARMS

Mains fault (normal source) : signalled locally by a yellow LED and remotely by dry contact with delay (failsafe).

• If the mains is not present or < 195 V.
• If the mains fuse is blown or not present.
• If the product is out of service.

Battery fault (emergency power) : signalled locally by a yellow LED and remotely by dry contact with delay (failsafe).

• If the battery is not present : The battery test is performed in the following manner: every 30 seconds for the first 20 minutes after commissioning : every 15 minutes after the first 20 minutes. If a fault is detected, the test is performed every 30 seconds up to 20 minutes after the fault disappears.
• If the internal impedance is too high (test every 4 hours maximum on a charged battery).The impedance limit value is :
• If the battery voltage :

No voltage on one of the Outputs : signalled locally by a yellow LED and remotely by dry contact with delay (failsafe).

5.2 SUMMARY OF AVAILABLE EQUIPMENT

Temperature compensation : A battery voltage compensation system maintains the charge characteristics within the limits specified by the battery manufacturer across the entire operational temperature range.

Battery low voltage cut-out : The cut-out threshold is :

The element causing the cut-out will be in the + position.

6. MAINTENANCE

In order to ensure maximal and durable service, we strongly recommend that your product be maintained clean and ensure that it is installed in a dry and ventilated location. We shall in no case be liable for damages associated with improper use or incorrect maintenance of the equipment. WARNING Replacing the original battery with a battery of incorrect type may result in an explosion hazard. Used batteries must be disposed of in compliance with recycling requirements.

7. FUSE PROTECTIONS

8. TROUBLESHOOTING PROCEDURE

If the Power supply does not deliver voltage :

• Check mains presence on the mains terminal strip

• Check the fuses

• Check the voltage value on output terminals

• The voltage on the battery cables must be identical to that of the load

• Check that each 12 Vdc battery has a voltage greater than or equal to 11.5 Vdc

• Repeat the measurement after having disconnected the load and the battery

• Recheck the signalling of the indicator lights (see chapter 5) · If all the steps are validated, check the compatibility of your load
  If the battery indicator light remains red :

• Check if the battery voltage is between 12Vdc and 30Vdc

• Check the battery voltage polarity

If the battery does not take over after a mains fault :

• Check the voltage on the battery terminals

• Check the battery fuse · Check the voltage on output terminals
  If the indicator lights are not illuminated :

• Check mains presence on the mains terminal strip

• Check the battery connection

• Check that the wire ribbon is properly connected

• Check the voltage on output terminals
