Observe the notes mentioned below when wiring to the power
supply terminal board.
Use the specified electric wire. Connect the wire securely to
the terminal. Lock the wire down without applying excessive
force to the terminal. (Tightening torque: 1.31
N.m
±
10%).
-
Do not connect wires of
a
different gauge to the same
power
supply terminal. Looseness in the connection may
cause
overheating.
-
When connecting wires of the same gauge, connect them
according to the
following
figure
:

-
When attaching the control box lid, make sure not to pinch
any wires.
-
After all wiring connections are done, fill in any gaps in the
casing wiring holes with putty or insulation material (field
suppl
ied
) to prevent small animals or dirt from entering
the
unit and causing short circuits in the control
box.
Do not connect wires of
a
different gauge to the same grounding
terminal. Looseness in the connection may deteriorate the
protection.
Use only specified wires and tightly connect
them
to the terminals.
Be careful that
the
wires do not place external stress on the
terminals.
Keep
them
in neat order so that they do not obstruct other
equipment
,
such as
by
popping open the service cover.
(
Make sure
the cover closes tight
ly
.
)
Incomplete connections could result in
overheating and
,
in the worst case, electric
al
shock or fire.
