2 – 2 – 5 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.
･
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.
There are two methods depends on model (specified power).
IDU3E-10 ~ 6E-10 (100V specified)
•
Insert the power plug into an outlet of 100V AC.
Install a Ground Fault Circuit Interrupter(GFCI) to the power supply (sensitivity of leak current
30mA and rated current 10A). (Prepare by yourself
)
•
Do not extend the power cable using power strip and so on. That causes decrease of the voltage and the product
cannot be operated.
IDU3E-20 ~ 6E-20 (200Vspecified)
•
Remove the terminal block cover or the rear cover in the rear of the product, and connect the power (200V AC)
to the terminal block.
•
Install a Ground Fault Circuit Interrupter(GFCI) to the power supply (sensitivity of leak current 30mA and rated
current 5A).(Prepare by yourself)
Specification of power cable
Prepare following power cable.
Power cable: 1.25mm
2
(16AWG), Three-cores (including the earth), External diameter: about 8 ~ 12mm
Additional length of about 0.1m 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 terminal block cover or the rear panel.
•
Insert the cord through the membrane grommet and connect it to the terminal block (refer to the label on the
terminal block).M3 screw tightening torque: 0.6~1Nm
During wiring work, do not touch other sections except terminal block.
•
Attach the cover or the rear panel as it were.
