Hitachi mini-HNRQ1 Series Service Manual page 42

Notes:
(1) Perform all the electrical work in accordance with this manual and in compliance with the local regulations and safety standards.
The electrical wiring should be applied by the qualified person.
(2) The recommended electrical characteristics are calculated by the related safety standards. The environment temperature is
less than 40°C, the length of the power supply wire is no more than 15 meters. If the air conditioning is in an extreme
environment, please calculate the electrical characteristics again.
(3) If the distribution box or pull box is adopted to the power supply for air conditioning, the size of the power supply wire should be
chosen according to the following table.
Total Ampacity
6<I≤10
10<I≤16
16<I≤25
25<I≤32
32<I≤40
40<I≤63
(4) The power supply wire should be stranded copper with shielding by neoprene.
(5) The transmission cables must be made up of the shielded twist pair cabling, and the shielded should be connected to the
ground.
(6) If the power supply wiring or the transmission cable is damaged, please turn off the power supply and contact the service dealer.
