Safety
This equipment is supplied by a mains voltage which can cause electric
shock injury. Before removing the machine’s cover, disconnect completely
the mains power supply and ensure that it cannot be connected
inadvertently by other persons.
If the cover is removed, do not apply power to the unit unless specifically
instructed to do so in these instructions. When working on live equipment,
exercise great care, use insulated tools and test equipment, and do not
work alone.
When testing or fault–finding the unit, exercise extreme care. Ensure that
any test equipment used is in good condition and capable of withstanding
the voltages existing. Tools used must have insulated hand grips. Test
probes and jumper leads must be in good condition and must have
adequate insulation. Test probes with claw ends and jumper leads must
not have insecure parts which may fail during use.
The power plug must be inserted in a socket outlet provided with a
protective earth contact. The electrical supply at the socket outlet must
provide over–current protection of 3 amperes. The socket outlet must be
within easy reach for isolation of the machine for cleaning and servicing.
