• Tightening the screws with too much force can
damage the GP unit's plastic case.
• In order to guarantee water repelling effect the
necessary torque is 0.52N•m [4.60Lb•in].
Wiring
• If the power connector is the following type,
please read "1. Wiring the Power Cord No.1".
• If the power connector is the following type, please
read "2. Wiring the Power Cord No.2".
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.

Connecting the GP Power Cord
(1) Confirm that the GP unit's Power Cord is
unplugged from the power supply.
(2) Use a flat-blade screwdriver (Size 0.4 X 2.5) to
loosen the terminal screws.
(3) Strip the power cord, and attach it to the power
connector.
(4) Use a flat-blade screwdriver to tighten the
appropriate terminal screws on the terminal
connector from step 3.
• The torque required to tighten these screws is
0.28N•m (2.5 [Lb•in]).
• The power connector cannot be removed because
it is mounted to GP unit. Do not attempt to
remove or tamper with the power connector. It
may damage the power connector.
• Be sure to loosen the terminal screws before pull-
ing out the power cord. The power connector may
be damaged by pulling the power cord when
attached to the power connector.
• Do not solder the cable connection.
Doing so may damage the unit due to abnormal
heat or cause a fire.
• Be sure to twist the power cords together, up to
the power connector.
