3. Electrical wiring
Warning
Carry out wiring work correctly, in accordance with electrical
equipment technical standards and interior wiring regulations.
Electric shocks or fires may result from incorrect wiring.
Install the ground wire securely, and make sure to carry out
grounding. Shocks may result when there is a malfunction or
fault current.
To prevent shocks, install a dedicated earth leakage breaker.
Before wiring the motor, measure the insulation resistance
using an insulation tester (DC 500 V megger). Confirm that
there is a value of 5M
or more between the motor lead wire
and the ground.
Caution
With 3-phase motors, check that none of the 3 motor terminals
is loose or has become separated. Phase interrupted
operation will result when the equipment is operated with 2
terminals, and the motor will burnout.
Perform wiring work correctly as specified by electrical facility
technical standards and extension codes. Incorrect wiring
could result in electric shock and fires.
(1) Carry out the wiring as per Fig.6 or displayed in the lid in the terminal box of the electric
motor.
(2) Please install an overload safety device in accordance with electrical equipment technical
standards and interior wiring regulations.
(3) Check the following conditions before turning on the switch:
(a) Installation of appropriate fuses.
(b) Correct wiring.
(c) Correct grounding.
