4.2.1 Connecting the Power Cord

• If the power connector is the following type, please read the following.

• If the power connector is the following type, please read from page 4-11.

WARNING

HAZARD OF ELECTRIC SHOCK

• Prior to connecting the GP unit's power cord terminals to the power terminal block, confirm that the GP

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 GP unit.

• Since there is no power switch on the GP 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.

Failure to follow these instructions will result in death or serious injury.

• When the FG terminal is connected, be sure the wire is grounded. Not grounding the

GP unit will result in excess noise and vibration.

• The SG and FG terminals are connected internally in the GP unit.

When connecting the SG wire to another device, be sure that the design of the

system/connection does not produce a shorting loop.
