Wiring
Warning
Only properly trained and qualified personnel are allowed to perform wiring work.
・
Before wiring, you must disconnect the power. Do not work under any energized
conditions.
・
Supply power from a stable source that 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 of the product should meet the specifications on page 6-1.
・
The product must be grounded for safety.
・
Do not connect ground wire to a water pipe, a gas pipe, or a lightening rod.
・
Do not plug too many leads into a single socket.
・
Circuit breaker must be properly selected to meet safety standard of local regulations.
・
Always be sure to connect the protective conductor first, disconnect it last in respect
to the other connections.
・
Be sure that the protective conductor has some additional length in respect to the live
conductors, so that it is not subject to mechanical stresses.
・
Be sure to install the circuit breaker correctly so that it disconnects all live conductors
and so that the operating handle can be easily accessible.
There are two methods depends on model (specified power).
IDU8E-10 ~ 15E-10 (100V specified)
•
Insert the power plug into an outlet of AC100V.
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.
IDU8E-20 ~ 15E-20 (200V specified), IDU8E-23 ~ 15E-23 (230V specified)
•
Remove the terminal block cover or the rear cover in the rear of the product, and connect the power
(AC200V or AC230V) to the terminal block.
•
Install a Ground Fault Circuit Interrupter(GFCI) to the power supply (IDU8E, 11E : sensitivity of leak
current: 30mA and below, Rated current 5A , IDU15E : sensitivity of leak current: 30mA and below,
Rated current 10A).(Prepare by yourself)
Specification of power cable
Prepare following power cable.
Power cable: 1.25mm
2
(16AWG), Three-cores (including the ground cable), External diameter: about 8 to
12mm.
Additional length of about 0.1m (4in) is needed to wire inside of the product.
Length of the power cable
The maximum length of the power cable should be no more than 30m.
Connecting to the power supply
•
Connect the power cable and the ground to the terminal block. Make sure to use the ring terminals
for M3 screws.
•
Applicable crimped terminal: 1.25-3 (Width: 6.5mm and below)
