6.6 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.

The working voltage should be higher than 90%
and lower than 110% of the rated voltage marked
on the name plate.

on the name plate.
¤Ł
The working voltage among the three phases
should be balanced with in a 3% deviation from
each phase voltage.

The starting voltage should be higher than 85% of
the rated voltage marked on the name plate.
2) Wiring
After the confirmation of the above conditions,
prepare the wiring as follows:

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.)

3) Earthing work
Connect the cable of diameter 1.6mm or more to the
earthing terminal provided in the control box and do
earthing. In case of equipping the electrical
resistance will be reduced to 500
