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.
- 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.
(1) Perform wiring firmly using heavy-duty cord with a nominal cross section of 0.75 mm
2
or larger and
isolate it sufficiently.
(2) HAA15-103, HAA22-143, and HAA37-143 use three phase motors.
The fan rotates backwards depending on the wiring method. Please check the rotation of the fan motor
when starting the operation.
This product operates normally if air is blown out from the front face of the cooler. If the air is inhaled,
perform wiring again by swapping the 2 out of 3 power supply cords on the terminal block.
(3) Make sure to perform grounding to avoid unexpected trouble. (Such as for panel mounting screws)
(4) Use an appropriate power supply voltage. The allowable voltage fluctuation range is +/-10% of the
rated voltage.
