GENERAL SAFETY
ELECTRICAL SAFETY
The HSS Extension Cables are designed to be used
with either a 415V, 5 pin 3-phase power supply or a
240V single phase power supply.
In addition, both types may be connected to a suitable
generated supply or to a main power supply.
If the equipment fails, or if its cable, socket or plug
becomes damaged, return it.
Never try to repair it
yourself.
Keep cables out of harm’s way,
and clear of the work
area
.
Cables must always be fully unwound and loosely
coiled, away from the equipment.
Never run them
through water, over sharp edges or where they could trip
someone.
Keep the equipment dry, using electrical equipment
in very damp or wet conditions can be dangerous.
To reduce the risk of electric shock, always use a
suitable RCD
(Residual Current
-
Operated Device)
available from your local HSS Hire Weld Depot. Or power
the equipment from a mains circuit with a built in RCD.
Ensure that all equipment powered by the extension
cable is switched OFF before plugging the extension
cable into the power supply.
GETTING STARTED

site in a
place where it will be away from pedestrian traffic.

There are two cable and plug sizes available. It is
extremely important that the plug rating is not
exceeded
(see chart), for further advice, contact your local
HSS Hire Weld Depot.
The HSS single phase cables have the trailing socket
fitted with a spring loaded cover
which engages with a
catch on the plugs body. This is the most common type used.
To make a connection,
raise the sockets cover, align
the plugs nipple with the sockets slot. Fully insert
the plug then lower the cover so that it engages
behind the plugs catch.
Whichever you are using…
All cables supplied by HSS use HO7 RN-F flexible
rubber cable and this must be taken into
consideration when performing your risk assesment.
If using an RCD adaptor, make sure that it is
positioned between the power supply and the
extension cable.
Having made sure that the power supply is switched OFF,
plug the cable into the power supply socket.
Having made sure that any equipment being supplied by
the cable is switched OFF,
plug the equipment into the
cable’s trailing socket.
You can now switch the supply ON and proceed to
operate the equipment.
