3.4 Electric wiring
3.4.1 GCD-051X･136X
（in the case of GCD-201X single phase motor specification）
(1) This pump has performed beforehand electric wiring by the side of a pump.
(2) Please insert the plug of the power cord of a pump in the wall socket of single phase 100V.
(3)
Fault load protection equipment (manual return type thermal protector) is built in this motor.
3.4.2 GCD-201X
（in the case of GCD-136X three phase motor specification）
(1)
The rotation direction of this pump is seen from the pump front (level gauge side), and is a
clockwise rotation.
(2)
If it wiring like fig.6, the rotation direction of a pump will be seen from the pump front
(level gauge side), and will be rotated clockwise. When you rotate in the opposite direction,
please shut off a power supply immediately, replace wiring connected to U and W, and
check rotating in the right direction anew.
(3)
Fault load protection equipment (manual return type thermal protector) is built in this motor.
(4)
When you form fault load protection equipment in the exterior of a 3-
phase
motor, please
refer to table 2.
A motor side grounding terminal is the screw with a display of "E" of the main part rear of
