7.5 Checking / replacing of fuses
The fuses for the mains and the battery power supply
are located in the related load disconnectors and at the
battery bank respectively.
The final circuits are also fused in the SKU modules, and
individual circuits are fused in other modules.
WARNING!
Do not open the load disconnector until the system
(ZB-S switch cabinet and any US-S substations) has
been isolated .
ATTENTION!
Never remove the fuses from the SKU modules or the
charging module LT .1 under load!
7.5.1 Checking the fuses of the mains and/
or battery power supply
First disable the controller of the ZB-S switch cabinet and
of the US-S substations (if any).

7.5.2 Setting of float charge voltage of the
Battery Control Module (BCM)
SAFETY NOTE
Safety notes are marked with this symbol in the main
instructions.
Please read these notes carefully before work begins!
Adjustment work at the system must only be done by
skilled electricians.
General Information
When central battery systems are supplied without
battery or the type of battery is unknown the tripple
charge-voltage is set up with the factory default of 245V
(means 2.27V/Z). According to the type of battery the
tripple charge-voltage must be fitted at face.
Adjust the tripple charge-voltage as follows:
1. Press and hold the service pin (1) of the BCM
for several seconds until the green LEDs flash
alternately. The control unit display is now controlled
by the BCM.
Make sure that no charge fault exists beforehand as
otherwise the CU CG-S activates an error display.
2. The voltage „U=“ (2), now shown in the display of
the CU CG-S control unit,
is the float charge
voltage to be set. The current displayed, „I=+“ (3),
represents the number of located CMs on the CCB
bus, 1A = 1CM.
3. Now set the float charge voltage with the „ISO
Test+“ and „ISO Test-“ buttons (4) according to
battery manufacturer specifications.
Battery Control Module BCM
CAUTION!
The float charge voltage is always set to the correspond-
ing value at a temperature of 20° C.
4. To save the voltage, press and hold the service
button (1) again until the green LEDs stop flashing.
Setting mode is terminated automatically after one
minute if the Iso Test buttons are no longer pressed.

7.5.3 Checking the fuses of SKU modules
For safety reasons, all SKU modules should first be isolated
by disabling the controller of the appropriate ZB-S (US-S).
To check or replace the fuses, proceed as described in
section 7.5.2.
