5) Maintenance
The load bank is designed to require minimal maintenance, a list of required maintenance checks is listed below in table
4.
The separate (external) 3-phase supply can be used to check the fan is operating correctly and to perform an insulation
resistance and load resistance test every 6 months. With control circuit powered from the external supply, run the fan,
and use the HMI to close all contactors (see load to 200kW and all contactors will close). Connect a suitable test device
(insulation tester and digital ohmmeter) to lug connections of the protective earth and power connection cables to make
the contact with the internal connectors. When checking the resistance ensure the resistance of the cables being used is
taken into consideration.
Walk around the unit and inspect for:
a) Obvious damage
b) Loose hardware
Inspect resistor duct – visual inspection
Insulation Resistance Test
Cold Resistance Check (0.8Ω Line to Neutral per phase)

Further maintenance should be completed by the manufacturer. Please contact us to arrange for the load bank to be
booked in for inspection, repair, and re-test.
6) Spares
Enquire with reference to resistor product code and serial number, as shown on rating plate.
