11/4/99 14:09 Electrical Installation 2-7
Power Connection AC power is supplied to ASM-20 through a standard 1.5 m (5 ft) detachable
power cord terminated by a standard 3-prong plug. The power inlet on the
rear panel incorporates an integral fuse.
Warning
Before connecting AC power to this unit, the protective earth terminals
of this unit must be connected to the protective ground connector of
the (mains) power cord. The mains plug should only be inserted in a
socket outlet provided with a protective earth contact. The protective
action should not be negated by use of an extension cord (power cable)
without a protective conductor (grounding).
Grounding: This unit will become dangerous if the protective
(grounding) conductor (inside or outside the unit) is interrupted or if
the protective earth terminal is disconnected.
An integral fuse is located above the AC mains socket on the rear panel.
Make sure that only fuses of the required rating are used for
replacement, as marked on the ASM-20 rear panel. Do not use repaired
fuses or short circuit the fuse holder. Always disconnect the mains cable
before removing or replacing the fuse.
If the fuse protection appears to have been damaged, render the unit
inoperative and secure it against unintended operation.
