4. EQUIPMENT REQUIRED FOR COMMISSIONING
4.1 Minimum equipment required
Multifunctional dynamic current and voltage injection test set.
Multimeter with suitable ac current range, and ac and dc voltage ranges of 0 – 440V and
0 – 250V respectively.
Continuity tester (if not included in multimeter).
Phase angle meter.
Phase rotation meter.
Note: Modern test equipment may contain many of the above features in
one unit.

blocks).
An electronic or brushless insulation tester with a dc output not exceeding 500V (for
insulation resistance testing when required).
A portable PC, with appropriate software (this enables the rear communications port to be
tested, if this is to be used, and will also save considerable time during commissioning).
KITZ K-Bus to EIA(RS)232 protocol converter (if EIA(RS)485 K-Bus port is being tested and
one is not already installed).
EIA(RS)485 to EIA(RS)232 converter (if EIA(RS)485 DNP3.0 port is being tested).
