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.
