7 Commissioning and other work
7.1 Safety Notes
WARNING! RISK OF INJURY!
Never switch the mains or battery supply on or
off under load (that means when final circuits are
switched on) .
For battery supply obtain: never disconnect or con-
nect cables to the battery bank under load and never
open or close the fuse switch for battery supply in the
cabinet under load .
7.2 Checking all connections
Before switching on the emergency lighting system:
check that the complete system is isolated and lock it
O
O
out. Do not restore the supply until all work has been
completed.
examine the condition of all cables and connections by
O
O
reference to the drawings and plans for the emergency
lighting system, and check that the installation work
complies with the relevant standards and codes of
engineering practice.
check that all connections and screw fastenings are
O
O
tight.
check all cable glands for tightness and seal quality.

7.3 Voltage measurements
Measurements of supply voltages and measurements
O
O
on the final circuits may only be carried out by qualified
electricians!
Be aware of the particular hazards when carrying out
O
O
measurements on multiple-phase power supplies!
Only use instruments with adequate voltage and
O
O
current strength!
All measurements within internal installations may only
O
O
be carried out by CEAG service engineers!
7.4 Insulation Testing
Check that the complete system is isolated and lock it
out. Do not restore the supply until all work has been
completed.
Insulation tests may only be carried out between the PE
conductor and every phase conductor L1, L2 and L3 as
well as between the PE conductor and the neutral con-
ductor N. Do circuits contain electronic equipment, the
neutral conductor and the phase conductor must be con-
nected while measuring.
Test voltage: max. 500V DC, Test current 1 mA!

DANGER!
7 Commissioning and other work
Use only measuring devices which are able to meet the
demands of DIN VDE 0413.
Disconnect the connecting cables for the mains and
O
O
battery supply.
Link the connections L and N of the switch cabinet
O
O
at the terminals of the mains supply or outgoing
distributors.
Carry out the insulation test as shown in below figure for
O
O
the connections of the mains supply (L/N) against
O
O
PE for the ZB-S cabinet and its outgoing circuits
and similarly for the US-S substations.
O
O
At the ZB-S (US-S) switch cabinet, link connections U1/
O
O
O1 etc. at the output terminals of the final circuits of
the cabinet and test the insulation for the final circuits
U1/O1 or U2/O2 etc. against PE.
On completion of the insulation tests, remove the
O
O
links across terminals L/N (on the mains supply and/or
outgoing circuits) and U1/O1 etc. at the terminal of the
final circuits.
Reconnect all disconnected cables and check the PE
O
O
connected on the cabinet door.
a)
ZB-S (US-S)
a: Insulation test on the power supply (mains)
b: Insulation test on final circuits
Linking L / N and U1 / 01 ( ... ) will protect active compo-
nents of the electronics in the ZB-S (US-S) cabinet and
of the luminaires (ballasts) from possible destruction!
