Warning
Only qualified persons are allowed to wire the product.
- Before wiring, be sure to shut off the power supply. Never perform wiring work while the
product is energized.
- Ensure a stable power supply with no voltage surges.
- Ensure that an ground fault circuit interrupter with appropriate capacity for ground fault and
load is used in the power supply of the product to prevent electrical shock and burnout of the
compressor motor. See “6-1 Specification table” for details.
- Use a power supply suitable for the specifications of the product.
- Be sure to connect the ground connection.
- Grounding should never be connected to a water line, gas line or lightning rod.
- Multiple wiring is dangerous because it may lead to heat generation and cause a fire.
- Do not modify the electrical wiring of the power supply.
- For use in Europe, install a breaker compliant with applicable IEC standards to the power
supply of the prodct.
[Wiring of power supply]
IDU15E1-23 (230V AC specification)
Remove the terminal block cover or the rear cover in the rear of the product, and connect the power
(AC230V) to the terminal block.
Be sure to install an ground fault circuit interrupter to the power supply. (To be prepared by the user.)
[Sensitivity of leak current: 30mA or less, Rated current: 10A]
Specifications of power supply cable
Prepare the following power supply cable.
Power supply cable: 1.25mm
2
(16AWG) or larger, Cable outside diameter Approx. 8 to 12mm, 3 cores
(including ground) Approx. 0.1m is necessary to route the internal wiring of the product.
Power supply cable length
The power supply cable length from the product should be less than 30m.
Terminal block
(refer to “1.1 Name and function of parts” for details).
Connect the power cable and the ground to the terminal block. The connection size is M3.
Be sure to use a round crimped terminal.
Applicable crimped terminal width: 6.5mm or less
[Wiring procedure]
1. Remove the terminal block cover or the rear panel.
2.
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: 0.63 to 1Nm
During wiring work, do not touch other sections except terminal block.
3. Re-attach the cover or real panel after wiring is done.
