This section describes the procedures and precautions for wiring power cords.
3.3.1 Connecting the Power Cord
„ AC Connections
Be sure to confirm that power is not being supplied to the PS-B unit before wiring . Failure
to do so can result in an electric shock.
Supplying a power voltage other than that specified will damage the power source and the
PS-B unit.
Since there is no power switch on the DC type PS-B unit, be sure to attach a breaker-type
switch to its power cord.
When the FG terminal is connected, be sure the wire is grounded.
• When the FG terminal is connected, be sure the wire is grounded. Not grounding
the PS-B unit will result in excess noise and vibration.
• The SG and FG terminals are connected internally in the PS-B unit.
When connecting the SG wire to another device, be sure that the design of the
system/connection does not produce a shorting loop.
The PS-B units is designed to use AC100V to 240V input. Supplying a power voltage other
than that specified will damage the power source and the PS-B unit.
