Installation of Unit
Power Supply and Wiring
The unit is completely wired internally at the
factory according to general rule of electrical
technology, but local rules, if they are required,
should be complied with.
1. Power supply
Power source must fulfill the following
conditions:
• The working voltage should be higher than
90% and lower than 110% of the rated
voltage marked on the name plate.
• The starting voltage should be higher than
85% of the rated voltage marked on the
name plate.

• Use the power supply cord(Rubber
insulation, type Ho7RNF approved by HAR
or SAA) suitable for the product's
electriccal capacity.
• Provide a recognized circuit breaker as
below between power source and unit.
A disconnection device to adequately
disconnect all supply lines must be fitted.
(for service operations)
• The screws which fasten the wiring in the
casing of electrical fittings are liable to
come loose from vibrations to which the
unit is subjected during the course of
transportation. Check them and make sure
that they are all tightly fastened.
(If they are loose, it could give rise to burn-
out of the wires.)
• See to it that the starting voltage is
maintained at more than 90 percent of the
rated voltage marked on the name plate.
• The following troubles would be caused by
voltage drop-down.
Vibration of a magnetic switch, damage on
the contact point there of, fuse breaking,
disturbance to the normal function of a
overload protection device.
*Separate main and heater power supply for
Z model. (Do not connect together to the
same power supply)
