Wiring Precautions; Connecting The Power Cord - Pro-face PS-3650A Series Hardware Manual

3.3 Wiring Precautions

This section describes the procedures and precautions for wiring power cords.
3.3.1

Connecting the Power Cord

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 the DC Power Supply Type model, be sure to attach a
breaker-type switch to the power cord.
When the FG terminal is connected, be sure the wire is grounded.
AC Power Supply Type
The PS-A units is designed to use AC85V to AC265V input. Supplying a power voltage
other than that specified will damage the power source and the PS-A unit.
• 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.
