Method For Connecting Electric Wire
Please carry out the wiring after consulting with local electric power company on local regulations.
(I) The entire wiring diagram of unit.
(II) Electrical wiring
Remove the panel on the right side M(4)RT060~120A/AR or the rear side M(4)RT150~420A/AR of the unit
and connect the units power supply wiring to the proper terminals in the control box.
Connect the wires by following the wiring diagram. Mis-connection will damage the controller.
a. Power supply
b. Main switch/fuse (field supply)
c. Power supply wiring for unit
d. Unit
e. Remote controller
f.
Connection wiring for unit / remote
controller (no polarity)
g. Earth
8. Electric Wiring
Construct The Earth Connection.
All electrical work must be carried out by a suitable qualied electrical trades-person and in accordance with
local supply authority requirements and associated regulators.
The unit is to be wired directly from an electrical distribution board either by a circuit breaker (preferred) or
HRC fuse.
Fix power source wiring to control box by using buffer bushing for sensible force (PG connection or the like).
Connect control wiring to control terminal block through the knockout hole of control box using ordinary
bushing.
NOTE : Earth wiring must be connected.
Arrangement such as terminal block in control box.
Note:
All electrical wiring must comply with
local electrical authority regulations.
(III) Wiring example and selection of earth leakage breaker
380~415V, 50Hz, 3Ø
The grounding wire must be of the same diameter as the power cable wires. The table above is an example.
The selection of other capacities should be determined in accordance with the relevant local standards, in
the country of installation.
