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.
