Section 1: Commissioning Preliminaries
Overview
Commissioning tests are carried out to prove:
a)
Equipment has not been damaged in transit.
b)
Equipment has been correctly connected and installed.
c)
Confirm that settings have been correctly applied.
d)
To obtain a set of test results for future reference.
1.1 Before Testing
Carefully examine the module to ensure that no damage has occurred during transit. Check that the
model number and rating information are correct.
1.2 Insulation
The relay, and its associated wiring, may be insulation tested between:
- all electrically isolated circuits
- all circuits and earth
An electronic or brushless insulation tester should be used, having a dc voltage not exceeding
1000V. Accessible terminals of the same circuit should first be strapped together. Deliberate
circuit earthing links, removed for the tests, subsequently must be replaced.
1.3 ARC Trip Verification
ARC Trip Verification will require a flash source to initiate sensor operation.
A high powered photographic flash is the most convenient means of initiating positive sensor
operation.
Note that mobile phone or small compact camera flashes may not have sufficient power to cause
sensor operation.
