Voltage:
The
FDS-360
operates on supply voltages between 95 and 125V AC.
It must not be plugged into 220, 230 and 240V AC outlets. If the unit is
accidentally connected to an AC supply giving in excess of 132V AC,
refer to
section 23
, (
See Figure 8.1
).
Frequency:
Both 60Hz and 50Hz are acceptable.

Grounding:
The
FDS-360
must always be connected to a 3-wire grounded
('earthed') AC outlet. The rack framework is assumed to be connected to the
same grounding circuit. The unit must NOT be operated unless the power
cables ground ('earth') wire is properly terminated - it is important for personal
safety, as well as for proper control over the system grounding. If the
electronic 0V has to be separated from the chassis and mains power earth,
refer to section 23
.
Connections:
The AC power cable has a moulded 3-pin utility plug attached
to the free end to facilitate the correct and proper connections.
AC Power Fusing:
The incoming line power passes through a 200mA (for 240V
only) anti-surge ('T') fuse, accessible from the rear panel (The fuse is rated at
250mA for 120V). If the fuse blows without good reason,
refer to section 23
.
Always replace with an identical 20mm x 5mm T rated fuse for continued
protection from equipment damage and fire.
Also see
section 22
for
information on replacing blown transient suppressors (if applicable).
Power ON:
Before turning on the power, it is worth checking that the three
frequency cards are installed correctly. Loosen the captive screw securing the
small cover plate on the lid of the unit, and inspect the cards. The slope and
frequency information is recorded on each of these cards, and it must be
ensured that all cards are fitted, regardless of whether they are required.
Refer
to sections 12 & 18
for more information concerning these cards.
The
FDS-360
outputs are instantaneously muted at power OFF. At switch on, a
delay prevents turn-off thumps propagating through the sound system.
