Load Bank Installation and Setup

Voltage and frequency ratings
It is important to realise that the external supply required for the fans and controls may be
of a different voltage or frequency from the Supply-on-Test. The voltage and frequency
ratings are specific to the equipment supplied and are shown on the rating plate.
Exceeding the voltage ratings or supplying the wrong frequency can cause damage to the
load bank so please check the plate carefully before starting the installation.

Consult the load bank’s rating plate for voltage and current ratings before
making connections
External supply wiring - the fan and controls power source
To use this load bank you are required to use an external power supply that is independent
of the Supply-on-Test. Refer to the load bank’s rating plate for the external power supply
requirements. The supply must be capable of supplying the fan motor starting current, and
must be fused accordingly.
Connecting the external supply
The external supply socket for the 8800 is mounted externally (see appendix drawings for
the exact location).
Anti-condensation heaters and lighting supply
The load bank is fitted with lighting and anti-condensation heaters for the switchgear
cabinets. It may be necessary to have these powered continuously, even when the normal
fan and controls supply is not available. Because of this the load bank is fitted with a single
phase AC line input connector which can be used to provide power for this equipment.
