Safety Warning
Maintenance work should be undertaken only by qualified personnel who are fully aware
of the danger involved and who have taken adequate safety precautions.
Always isolate all the supplies to the equipment before inspecting, moving equipment,
removing or replacing parts.
Work on the equipment while the electrical supplies are connected is not normally
necessary. If it should become necessary for any reason, take extreme care not to come in
to contact with live parts.
You should remain alert at all times when the unit is in operation. There are three main
sources of danger:
Electricity can kill.
Serious injury or death could result from contact with electrically live
parts. Even though the connections to the load bank may be temporary, they must always
be made to the same standards as if they were permanent.
Load banks contain fast moving parts.
The fan, in particular, can cause serious injury if
you come into contact with it when it is in operation.
Load banks produce a lot of heat.
When a test is in progress the resistive element can
glow cherry red. The heat they produce is removed by the air that the fan forces past them,
but that air in turn can become very hot.
