CEAG Notlichtsysteme GmbH
The fuses for mains and battery supply
are arranged in the pertinent load-break
switches (Fig. 3, Items 9 and 11) or on
the battery bank.
Moreover, in the SKU modules fuses
are provided for the final circuits with
individual circuits being fuse-protected in
other modules.
Warning!
Exclusively open the load-break
switches if the system (EURO
ZB.1 control cabinet and any
EURO US.1 subsystems) has
been disconnected first (see
Section 12.2 „Disconnecting/
Switching-on an Emergency
Lighting System und Battery
Power Supply“).
Attention!
Never remove fuses under load
on SKU modules!
Testing the fuses of the mains and
battery power supply systems
For this purpose the control system
of the EURO ZB.1 control cabinet and
EURO US.1 subsystems, if any, must be
blocked.
Proceed as outlined under Section
12.2 „Disconnecting/Switching-on a
EURO ZB.1 Control Cabinet or EURO
US.1“.
Open the load-break switch for the
mains and battery supply.
On the EURO ZB.1 control cabinet
and EURO US.1 subsystems, if any,
check whether all fuses in the load-
break switch for mains and battery
supply
– meet the prescribed technical
specifications and
– have been correctly inserted/
mounted
– are free from defects.
Testing the fuses on SKU modules
For safety reasons all SKU modules
should first be disconnected (de-ener-
gized) by blocking the control system of
the relevant EURO ZB.1 control cabinet
(EURO US.1)
(see Section 26).
As regards testing or replacing fuses
proceed as described against 12.5.
