G3 Switch position ON (ONLY OPTIONAL)
This switch position is used for operation without the Bicker UPS system, in the normal delivery state this is
deactivated and is only activated on customer request. The MOSFET main switch is always enabled (the system
present function is bridged). It is not necessary to use the communication connector for operation.
The function of the power button changes when activated as follows:
According to an 8S system with lithium iron phosphate batteries, the voltage at the main power plug can vary
between 19.2 V and 29.2 V depending on the state of charge. The battery can be discharged and charged accor-
ding to the given limit values.
Recommended end-of-charge-voltage: 27.6 V (=3.45 V per cell level)
Max. discharge current: 15 A
Max. charge current: 6 A
The maximum capacitive load, the battery can charge, is 1000 µF. Otherwise the battery detects a short circuit
and blocks the main current path.
IMPORTANT:
In switch position
ON
the battery is always on standby, so the BMS shows permanently the highest idle
consumption. The integrated power saving modes of
UPSI
operation are largely inactive. The battery
must not be stored in the
ON
switch position permanently. If a completely discharged battery is left in the
ON
position, the battery will be deeply discharged within a few hours! It is recommended to recharge the
battery as soon as possible after discharge and to set it to the
OFF
position when not in use.
