DC/DC converter
This module (Fig. 47) energizes the elec-
tronic components of the control cabinet
at the required operating voltage (24 V
and 6 V DC). Voltage supply is achieved
via the batteries independently of the
mains supply.
The LEDs (2) light up if voltage has been
applied.
Note that electrical arcing or shocks may
be encountered if an insolator of the
battery power supply is opened before
the system (and pertinent substations,
if any) have been correctly blocked and
disconnected from the mains supply.
Moreover, electric shocks or short cir-
cuits may arise if work is carried out on
final circuits that have not been discon-
nected from the supply before. It must
also be considered in what way lighting
in building zones may be affected when
you interrupt the power supply to final
circuits.

BCM
This module (fig. 48) controls the charging
condition of batteries and their charging.
Settings via the service key (1) are imple-
mented by the factory or by trained service
personnel during maintenance. The LEDs
(2) signal the operating state of the BCM
(from above):
Operational readiness (LED lights up), boost
charge active.
LED (3) and button (4) belong to the in-
stalled insulation monitors for ISO fault batt.

CM 1.7 A and CM 3.4 A
Charging of the batteries is via the charge
modules. Charging modules CM 1.7 A and
CM 3.4 A (fig. 48).
Setting of the max. 32 addresses via rotary
coding switch (5 = 10-; 6= 1-address range)
is implemented by the factory. LEDs (7)
signal the operating state of the charging
module. Operational readiness (LED lights
up).
