mounted.
4.1. Connect mains 230 V AC
Connection of 230 V mains cabling to the unit takes place through the device connector on the back
of the unit. Connect the power supply to the mains via easily accessible isolation switch and suitable
ground fault protection (which is part of the building's existing wiring).
4.2. Temperature sensor
Temperature sensor for measuring battery temperature, place sensor between batteries.
The device has an internal temperature sensor and an external temperature sensor to measure internal
and ambient temperature.

4.3. Alarm
See table 6.1-6.3 [6]
4.4. Alarm cable for battery fuse monitoring
Alarm cable for battery fuse monitoring.
4.5. Communication - optional
Connection to communication (via RS-485) can take place during customer customization.
4.6. Maximum wire resistance
The voltage at the furthest load point must not be lower than the requirements of the connected load.
Lowest voltage is given when batteries are almost discharged (21 V / 42 V) together with voltage drop in
wiring. Ensure that the load can handle the lowest voltage with voltage drop in cabling.
4.6.1. Facts about ILAST
ILAST is the sum of the connected loads. The cable resistance (RKABEL) is the sum of the cable
resistance in both conductors x the cable length.
Minimum load voltage in battery operation taking into account voltage drop in cables = VUT(MIN) -
(ILAST x RKABEL). VUT(MIN) is the limit for deep discharge (21 V / 42 V) when the batteries are
empty.
The table takes into account to and from conductors, i.e. the actual distance in meters must be used.
RKABEL Ω/ m

Use the included cabling to connect the batteries. Be careful not to short the terminals of the batteries.
First connect wiring in batteries, (2). Cabling must have rubber pole protection that covers the battery
pole. Then connect battery connector to the battery backup, (1).
5. SET BATTERY CAPACITY
Table 4. Set battery capacity
No Explanation
1 Set the steering wheel so that V lights up green.
2 Press and hold the multi selector for three seconds until C00 appears on the display.
Turn the multi-selection dial until C01 is displayed and press the multi-selection dial (a light push) to select the battery
capacity.
To accept the setting, press and hold the button for three seconds.
• Factory default setting is 2 x 20 Ah.
• Turn to C00 and press the button once to return to the regular menu.
NOTE
The device retains settings even if power is completely cut to the device. You therefore
do not need to set the battery capacity again when changing the battery.
6. HOW TO START THE DEVICE
After connection, start must take place in the following steps:
1. Connection/voltage setting of battery part.
10

2. Voltage setting to mains.
3. Apply voltage to the load by switching on the circuit breaker.
7. COMMISSIONING
When all connections have been made, the system has been configured and the three steps for how to
start the device have been completed - then the following should happen:
• Status indication is off in normal operation.
• The load will be powered. Check with a voltmeter that the load voltage is between 26 and 27.3 V DC
(48 V, 52-54.6 V DC).
• The batteries must be charged. Check this by measuring across the battery terminals. (Depending
on the condition of the batteries, the voltage may vary but should be above 24 V DC, (48 V DC) and
slowly increase by approximately 0.001 V/10 sec. When fully charged, the voltage of the batteries
should be 27.3 V DC (48 V, 54, 6 V DC).
• The ALARM indicator diode on the panel must be off.
• All fault alarm relays must be in the pulled state. Check that there is a connection between CO and
NC. Set the measuring instrument to continuity measurement and test termination. This should then
indicate a short circuit.
• All relay outputs are normally energized and thus give an alarm in de-energized mode. When con-
necting to communication, the parent system sends queries. The superior system must then give an
alarm if, for example, the unit is de-energized.
8. COMMUNICATION - OPTIONAL
Connection to communication (via RS-485) can take place during customer customization.

Installation control batteries
1. Check that the battery is completely clean and that the terminals are free from corrosion.
2. Check and note the temperature in the battery compartment.
3. Check the terminal voltage of each battery before installation. If the difference between the batter-
ies exceeds 0.5 V, the battery loop should be equalized in connection with installation. If any
battery has a terminal voltage of less than 12V, this battery must be replaced with a new battery
and reported to the supplier.
4. Connect the battery and check the charging voltage. The charging voltage should be between 2.25
V - 2.27 V per cell = between 13.5 V - 13.62 V for a 12 V system and between 27.0 V - 27.24 V for
a 24 V system.
Year-round inspection
1. Check that the battery is completely clean and that the terminals are free from corrosion. If there is
corrosion on the terminals: Check that the battery does not leak acid. Then clean the terminals and
reconnect the battery. Then lubricate with battery terminal grease over the connected terminal.
13

2. Check and note the temperature in the battery compartment.
3. Check and note the average current.
4. Check that all connections are securely fastened and that there is no gap in the connection.
5. Check that the fan (if units have a fan) is working properly. Clean the fan if necessary.
6. Check the charging voltage by measuring with a multimeter between the connection points + &
amp; -. The charging voltage should be between 2.25-2.27 volts per cell = between 13.5-13.62V for
a 12V system and between 27-27.24V for a 24V system.
7. Turn off the rectifier and let the batteries rest for 10 - 15 minutes. Then measure the terminal
voltage of each battery. After resting, the terminal voltage must be between 12.9 V - 13.5 V.

Info Explanation
Status indication LED, display and communication output (RS-485).
Communication protocol RS-485 Milleprotokollet - Optional
Error output Potential-free relay switches rated 1 A @ 30 V DC (all fault outputs).
Self consumption, (in bat-
tery operation) 24 V units: 270 mA. 48 V units: 200 mA
Switching time Batteries rest for 20-day cycles, after which a charging cycle picks up and charges the batteries
for 72 hours. If there is a power failure when the batteries are in the charging cycle, there is no
switching time.
Deep discharge Deep discharge protection is activated: 1U / 24 V and 2U / 24 V systems when the power supply
voltage is below 19 V DC. (1 U / 48 V and 2 U / 48 V systems when the power supply voltage is
below 38 V DC.)
Tension, ripple less than 210 mVp-p in normal operation. (Max 2 V in ripple voltage when recharging batteries,
when the power supply goes within the current limit).

Off Normal operation -
1 blink Network outages -
2 flashes Delayed network
failure 10 second delay.
3 flashes Charger error If the batteries have not reached the desired voltage (26.7V) after completing the charg-
ing cycle. If the power supply drops below the limit value (26.5V) during the current
dormant phase for the batteries. If the voltage from the power supply drops during the
connection test for the batteries that occurs every 10 seconds. At low voltage in the
power supply (26.7V), the batteries are disconnected every 10 minutes, if low voltage in
the power supply remains an alarm is given. If the mains voltage is below system voltage
(24V) during mains operation, an alarm is given.
4 flashes Surge power sup-
ply Voltage above 27.9 V DC (24 V), / 55.8 V DC (48 V).
5 blink Battery fault Aged batteries, failed weekly test. Cell test, the internal resistance of the battery has
risen above the limit value. Failed connection test. Batteries are not connected or battery
voltage below 16 V.
6 flashes Low battery volt-
age Low battery voltage in battery operation.
7 flashes Summarmarm Temperature alarm, the temperature is below or above the limit value. Fuse failure, load
or battery fuse has blown. Fuse fault from external card with load outputs. Ground fault
(D-Sub). Signal error (D-Sub). The temperature sensor is incorrect or missing. Fan fault.
8 blink System error The system is not calibrated.
