WARNING
GROUNDING: This unit should always be grounded through the
protective earth lead of the power cable.
When connecting AC power to this unit, the mains plug should only be
inserted in a socket outlet provided with a protective earth contact. The
protective action must not be negated by use of an extension cord
(power cable) without a protective conductor (grounding). Interrupting
the protective (grounding) conductor (inside or outside the unit), or
disconnecting the protective earth terminal can make this unit
dangerous.
The line fuse is located in an integral-type fuse holder located on the rear
panel (as shown in Figure 3-1). Make sure that only fuses of the required
rating, as marked on the rear panel, are used for replacement. Do not
use repaired fuses or short-circuit the fuse holder. Always disconnect
the mains cable before removing or replacing the fuse.
Whenever it is likely that fuse protection has been damaged, make the
unit inoperative and secure it against unintended operation.
