WARNING!
If using an extension cable or power strip
ensure that the total current rating (amperes)
of all connected equipment is less than the
maximum rating of the extension cable, power
strip or wall outlet. Otherwise fire or shock
may occur.
If this product is already supplied with a fitted
power strip then NO additional power strip or
extension cable should be used to connect to
the mains wall outlet.
Ensure the power cable is routed so as not to
be damaged or cause a trip hazard. If the cable
becomes frayed or damaged, replace it
immediately to prevent any risk of shock.
Do not twist, constrict or knot the power cable
as this can cause overheating which may lead
to fire or electric shock.
Ensure the power socket to which this product
is connected is easily accessible at all times.
Do not connect or disconnect the power plug
with a wet hand as this may cause electric
shock.
