Commissioning and other work
7.1 Checking all connections
Before switching on the automatic test system:
check that the complete system is isolated and lock it out. Do not restore the supply until all work has been
completed.
examine the condition of all cables and connections by reference to the drawings and plans for the automatic
test 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 tight.
check all cable glands for tightness and seal quality.
7.2 Voltage measurements
Measurements of supply voltages and measurements on the final circuits may only be carried out by qualified
electricians!
Be aware of the particular hazards when carrying out measurements on multiple-phase power supplies!
Only use instruments with adequate voltage and current strength!
All measurements within internal installations may only be carried out by CEAG service engineers!
7.3 Insulation Testing
Check that the complete system is isolated and lock it out. Do not restore the supply until all work has been
completed.
DANGER!
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 conductor N. Do circuits contain electronic equipment, the neutral
conductor and the phase conductor must be connected while measuring.
Test voltage: max. 500V DC, Test current 1 mA!
Use only measuring devices which are able to meet the demands of DIN VDE 0413.
Disconnect the connecting cables for the mains supply.
Link the connections L and N of the switch cabinet at the terminals of the mains supply or outgoing distribu-
tors.
Carry out the insulation test as shown in below figure for
- the connections of the mains supply (L/N) against PE for the AT-S
+
cabinet and its outgoing circuits
- and similarly for the substations.
At the AT-S
+
switch cabinet, link connections U1/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 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 connected on the cabinet door.
