4. Safety instructions
Warning! This device may only be installed by trained personnel or qualified engineers!
Please read carefully the instructions in this manual before use. Keep this user manual nearby for
anytime reference.
The unit may only be operated at a power receptacle with protective earth conductor – safety
class1.
Warning!
The protective earth conductor must never be interrupted even for test purposes! This may
be dangerous to life!
1. Check your local mains voltage before connecting the EPM 6-30-EN54. This device is
normally set up for an AC line voltage of 230 Volts, 50 to 60 Hz. The local rules and regulations
have to be observed.
2. Connect the device to the battery with correct polarity!
3. Before operating check all connections for correct polarity!
Disconnect the power cord before removing the cover.
When repairing devices, the general precautions and actions regarding electrostatic discharge
have to be taken.
The Emergency Power Manager EPM 6-30-EN54 is intended for use over a range of ambient
temperatures from –5°C to +40°C. During transport or storage temperatures from –20°C to +70°C
are permissible.
This appliance may only be used in accordance with its intended purpose: Power supply unit,
output distributor and battery charger for voice alarm systems.
A high current fuse has to be inserted externally into the main battery connection.
Use only VRLA (= valve regulated lead acid) batteries. Replace batteries only with the same type,
otherwise there is the danger of explosion, as charging current or end-of-charge voltage may be
too high.
Special care has to be taken when connecting or changing batteries. There is the danger of
explosion, if batteries are shorted.
Batteries have to be disposed or recycled only according to the local rules and regulations.

7. Functional description
The DC UPS uses the on-line structure to provide constant power without interruption. The
6 channel outputs use 6 independent fuses for protection. Any short circuit of one channel, the fuse
cut the current in short time to protect the other channels from power interruption.
The smart charger provides 27.2Vdc charging voltage when thermal sensor is not used. The
charging voltage provides temperature compensation when thermal sensor is connected. The
thermal-compensated charging voltage can maximize the battery life time especially for
lead/calcium batteries.
In the normal mode, the charger will charge the battery and supply constant power to the output.
The charging current will reduce when load current increases. Sometimes if the peak load current
is over the level that charger can supply, the battery will supply the load current at the same time.
When battery is fully charged, the charging voltage will become temperature compensated. In case
of mains power failure, the charger will stop providing current, and the battery will take over to
maintain the output voltage. In addition, the EPM 6-30-EN54 provides auxiliary outputs.
Battery failure: The outputs 1,2,3 are supplied by the internal power supply with power.
The Outputs 4,5,6 are separated after 30 minutes from the internal power supply.
Main power failure: The outputs 1 ~ 6 are powered by the battery.
8. Monitoring functions
The AC IN / Charger OK – LED (green1) lights up when AC input is good and charger can provide
current to the battery. In case of blackout or charger failure, this LED goes out and the error will be
reported via the dry contact signal pin1~3, pin1, pin2 become open circuit from short. A beeper will
sound with a double beep per minute.
The Controller OK – LED (green2) lights up when the controller is operating without fault. If the
controller is not operating properly, this LED goes out and the error will be reported via the dry
contact signal pin4~6, pin4, pin5 become open circuit.

If the battery voltage sinks below approx. 20.0 V DC in an emergency power case, the Battery
Low LED (yellow1) lights up as a warning.
The emergency power ends at battery voltage of approx. 18.0 V. The total discharge protection
then separates all consumer outputs from the battery.
If the battery and the battery circuit (including internal and external cell connectors and fuse) are
too high in impedance (over 0.1 Ohm), the Battery Fail – LED (yellow2) lights up after approx.
1 minute later when power on and the fault will be reported via the dry contact signal pin7~9, pin7,
pin8 become short circuit.

9. Important Installation Instructions
9.1 Additional items needed
To build up a complete emergency power supply – besides the battery – a set of cables and a
special battery fuse for high current has to be added. These parts have to be evaluated for
maximum current load and hence they are not in the scope of supply.
9.2 Temperature sensor
When temperature sensor is open circuit or not installed, the end-of-charge voltage will be set
automatically to 27.2V.
The temperature sensor line should be located as close as possible to the emergency power
batteries, but not mounted directly on the battery itself. Do not bring the temperature sensor into
contact with heat-dissipating components.
9.3 Self-test and Test Cycle
Upon starting up the emergency power supply with system monitoring, an automatic self-test is
carried out. The function monitoring for the battery circuit is not active until the first test cycle is
done, approx. 1 minute after startup. A test cycle then takes place every 32 minutes.
9.4 Remote Battery Discharge Test
In the EPM 6-30-EN54 a test function is implemented. When shorting the 2 pins of remote battery
discharge test control input (pins C/D, see above), the charging function is switched off and so the

UPS is forced to test the battery to low battery alarm. Anytime when the two pins (C/D) become
open circuit, it will end the discharge test.
9.5 Consumer Output Fuses
The maximum current load may not exceed 30 A at each output, the maximum value for DC fuse is
40 A for each channel. A lower value of fuse can be used when maximum load current is much
lower than 30 A.
The consumer output fuses are preassembled with 40 A blade fuse links. These fuses have to be
adapted to the consumer output currents and used wire cross-sections.
Formula:
Fuse value = max. consumer current x 1.3.
9.6 Main Battery fuse
Into the battery connection a high current fuse has to be inserted. The fuse value has to be
determined according to the maximum total battery current:
Fuse value = maximum total battery current x 1.3.
Since charging current is 8 A maximum, the main battery fuse must be 16 A minimum.
9.7 Calculating battery capacity
As mentioned in the Technical Specifications below, battery capacity may be minimum 32 Ah and
maximum 150 Ah. These limits are predefined on one hand by the charging current (for every
battery type always a maximum charge current is specified) and on the other hand by the charging
time, which is determind in the EN 54-4 standard. In this standard a charging time of 24 hours for
80% of the rated capacity is required.
Furthermore the battery capacity has to be calculated regarding to:
1. The energy demand during a mains failure. Times of system standby and full power condition
have to be considered.
2. Additional consumer loads, who draw current also during mains present condition. These
currents have to be subtracted from the rated charging current of 8 A. Of course this will increase
the charging time.
9.8 Please note:
In case of present mains power, an output current exceeding 8 Amperes will discharge the
battery! The internal beeper will sound continuously in that case.
