CAUTION
•
Be sure to use crimp-style terminal with insulating sleeves for con-
nections. (See the figure below.)

• For wiring, use the designated power wire and connect firmly, then
secure to prevent outside pressure being exerted on the terminal
board.
•
Use an appropriate screwdriver for tightening the terminal screws.
A screwdriver with a small head will strip the head and make proper
tightening impossible.
•
Over-tightening the terminal screws may break them.
See the following table for the tightening torque of the terminal
screws.

When pulling the ground wire out, wire it so that it comes through
the cut out section of the cup washer. (See the figure below.) An
improper ground connection may prevent a good ground from being
achieved.

When 2 wires are connected to a single terminal, connect them so
that the rear sides of the crimp contacts face each other. Also, make
sure the thinner wire is on top, securing the 2 wires simultaneously
to the resin hook using the included clamp (1).

9 .6 . Procedure for Wiring Inside Units
• Referring to the figure below, secure and wire the power and trans
-
mission wiring using the included clamp (1), (2) and (3).
•
Wire so that the ground wiring does not come into contact with the
compressor lead wiring.
If they touch, this may have an adverse effect on other devices.
•
The transmission wiring must be at least 2 in. (51 mm) away from
the power wiring.
•
Route wiring so that it does not come into contact with the high-
temperature pipes (indicated by the hatching in the figure below) or
the port pipes (see figure below).
