2.2.4 Electric Wiring
Warning
No one but qualified person should do the wiring work.
Before wiring, you must cut the power off for safety. Do not work under any energized conditions.
Supply power from a stable place, which is free from the effect of surge.
Refering to “6-1 Specifications,” make sure to install a e
lectric leakage breaker that has right
short
circuit capacity and load capacity to prevent electric shock or burnout of the motor of the
refrigerator.
Supply power for the equipment should meet the specifications.
The equipment should be grounded for safety.
Do not connect the earth to a water pipe, a gas pipe, or a lightening rod.
Do not plug too many leads into a single socket. That causes exothermic heat or fire.
Do not convert the wiring to use.
In European countries, a circuit breaker that meets the IEC standard should be used for the
supply power.
Wiring procedure
* The power cable should be supplied by the customer.
1. Remove the panel from the right-hand side of the dryer and lead the power cable from the power cable
entry on the back panel.
2. Lead the signal cable from the signal cable entry in the same way as the power cable.
3. Connect the power cable, earth wire and signal cable to the terminal block. (Tightening torque: 0.6 to 1Nm)
4. Turn the leakage breaker on.
5. Mount the cover on the terminal block and mount the panel on the right-hand side.
