Mains Power Connection

Voltage: The FDS-310 operates on either 115 or 230 volt supplies. Use the
voltage selector switch to choose the required voltage setting. (See Figure
8.1).
Frequency: Both 60Hz and 50Hz are acceptable.

Grounding: The FDS-310 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
cable's ground ('earth') wire is properly terminated - it is important for
personal safety as well as for proper control over the system grounding. To
'lift' the signal ground (0V), refer to section 21.
AC Power fusing: The incoming line passes through an anti-surge ('T') fuse,
accessible from the rear panel. If the fuse blows without good reason, refer to
section 20. Always replace with an identical 20mm x 5mm 'T' fuse, rated at
200mA or 250mA for 230V or 115V settings respectively, for continued
protection from equipment damage and fire.
Power ON: This is indicated by either of the green and yellow LEDs on the
left side of the panel, labelled 'MONO 3-WAY' and 'STEREO 2-WAY'
depending on the mode you have selected. If neither of these LEDs are lit
when the power is connected and the power switch is depressed, refer to
section 20.
