2.2.5 Electric wiring
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]
There are two methods depends on model (specified power).
IDF15E1-10 (100V AC specification)
Insert the power plug into an outlet of AC100V.
∗
Be sure to install an
g
round fault circuit interrupter to the power supply. (To be prepared by the user.)
[Sensitivity of leak current: 30mA or less, Rated current: 10A]
Do not extend the power cable using power strip and so on.
That causes decrease of the voltage and the product cannot be operated.
IDF15E1-20 (200V AC specification)
Remove the terminal block cover or the rear cover in the rear of the product, and connect the power
(AC200V) 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.
