Summary of available equipment
5.2.1
Battery test
The battery presence test is performed in the following manner: every 30 seconds for the first 20 minutes after
commissioning and every 15 minutes after. As soon as a fault is detected, the test is performed every 30 seconds
until 20 minutes after the fault disappears.
The impedance measurement test occurs every 4 hours if the mains is present on the power supply and if his
current is < 12A. The impedance limit value is 16m
10 %
in 24V and 32m
10%
in 48V if the jumper is set on '75',
and becomes 24m
10%
in 24V and 48m
10%
for 48V if the jumper is set on '50' (see chapter 1.2.5).
5.2.2
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.
5.2.3
Battery low voltage protection:
-
The battery low voltage protection threshold is 21,6 V
±3 %
(SON 24V 12A MS150 RACK) or 43.2 V
±3 %
(SON
48V 12A MS150 RACK).
-
The element causing the cut-out will be in the + position.
5.2.4
Battery reverse connection protection
-
At start-up : the battery relays will not close
-
During operation : the fuse F8 will blow out

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.
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.
