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.

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 13 m
Ω
±10 %
in 24V and 26m
Ω±
10%
in 48V (see chapter 1.2.5).
If
the battery voltage < 1.8 V/cell
±3 %.
No voltage on one of the Outputs:
signalled locally by a yellow LED and remotely by dry contact with delay (failsafe).

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 1.8 V/cell
±3 %.
The element causing the cut-out will be in the + position.
