12.5.1 With the Relay De-energized

12.5.1.1 Visual Inspection
After unpacking the product, check for any damage to the relay case. If there is any damage, the
internal module might also have been affected, contact the vendor. The following listed items are
necessary.

Protection panel
Carefully examine the protection panel, protection equipment inside and other parts inside to


Panel wiring
Check the conducting wire which is used in the panel to assure that their cross section
meeting the requirement.
Carefully examine the wiring to see that they are no connection failure exists.

Check whether the earthing cable from the panel terminal block is safely screwed to the panel
steel sheet.

Switch, keypad, isolator binary inputs and push button
Check whether all the switches, equipment keypad, isolator binary inputs and push buttons
work normally and smoothly.
12.5.1.2 Insulation Test (if required)
Insulation resistance tests are only necessary during commissioning if it is required for them to be
done and they have not been performed during installation.
Isolate all wiring from the earth and test the isolation with an electronic or brushless insulation
tester at a DC voltage not exceeding 500V, The circuits need to be tested should include:
