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.
･
Ensure that a Ground Fault Circuit Interrupter(GFCI) with appropriate capacity for earth
leakage and load is used in the power supply of the product to prevent electrical shock
and burnout of the compressor motor. See “6-1 List of specifications” for details.
･
Supply power for the product should meet the specifications.
･
The product 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.
How to connect wiring
・
Take off the front panel in front of the product and connect the power supply (AC200V) to the terminal base.
・
Install a Ground Fault Circuit Interrupter(GFCI) to the power supply (Prepare by yourself)
[Sensed current: 30mA and below, Rated current 10A (Rated current 15A for IDF75E)]
Specification of power cable
Prepare following power cable.
Power cable: 1.25mm
2
(16AWG), External diameter: about 8 to 12mm
IDF22E-20, IDF37E-20(single phase power supply) …3 cores (including grounding)
IDF22E-30, IDF37E-30, IDF55E-30, IDF75E-30(3 phase power supply) …4 cores (including grounding)
Additional length of about 0.2m is needed to wire inside of the product.
Length of the power cable
The length of the power cable should extend less than 30m from the product.
Connecting to the power supply
Connect the power cable and the earth to the terminal block. M3 screw is used for the connection part. Make sure
to use round crimped terminal.
Applicable crimped terminal: 1.25-3 (Width: 6.5mm and below)
Wiring procedure
・
Remove the front panel.
・
Insert the cord through the rubber grommet and connect it to the terminal block (refer to the label on the terminal
block).
M3 screw tightening torque: 0.6 to 1Nm
During wiring work, do not touch other sections except terminal block.
・
Attach the front panel as it were.
