Wiring Precautions
This section describes the procedures and precautions for wiring power cords.
3.2.1
Connecting the Power Cord
AC Connections
To avoid an electric shock, prior to connecting the PS-A unit’s power cord terminals to the
power terminal block, confirm that the PS-A unit’s power supply is completely turned OFF,
via a breaker, or similar unit.
Supplying a power voltage other than that specified will damage the power source and the
PS-A unit.
Since there is no power switch on PS3650A-T41-24V/PS3651A-T41-24V, be sure to attach
a breaker-type switch to the 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-A unit will result in excess noise and vibration.
• The SG and FG terminals are connected internally in the PS-A 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-A units is designed to use AC100V to AC240V input. Supplying a power voltage
other than that specified will damage the power source and the PS-A unit.
• The power cord included in the package, is designed only for AC100V use.
Under other voltage situation, you should use a different cord in conformity with
the voltage.
