(4) Put the control box cover, and wrap the wire sealing mate-
rial (Small) (10) around the conduit so as to block the wire
through holes.
CAUTION
• After all the wiring connections are done, fill in any gaps in the
through holes with putty or insulation (procured locally) to pre-
vent small animals and insects from entering the unit from
outside. (If any does get in, they could cause short circuits in
the control box.)
[Precautions for Power Supply Wiring]
• Connect round crimp-style terminals provided with insulation
sleeves to the terminal block for power supply.
Be sure to follow the instructions provided below if the spec-
ified terminals cannot be used.
Otherwise, abnormal heat may be generated as a result
of the loosening of the wires.
• If stranded wires are used, do not solder the front end of the
wires.
• Connect proper wires securely and fix the wires so that exter-
nal force will not be imposed on the terminals.
• Use an appropriate screwdriver to tighten the terminal
screws. The screw heads may be damaged if the screwdriver
is too small and the terminal screws will not be tightened
properly.
• Do not tighten the terminal screws excessively, or otherwise
the screw heads may be damaged.
• Refer to the table below for the required tightening torque val-
ues of the terminal screws.
