Observe the notes mentioned below when wiring to the terminal block for wiring the units.
CAUTION
•
When clamping wiring, use the included clamping material to prevent outside pressure being exerted on the
wiring connections and clamp firmly. When doing the wiring, make sure the wiring is neat and does not
cause the terminal box lid to stick up, then close the cover firmly.
•
When attaching the terminal box lid, make sure you do not pinch any wires.
•
After all the wiring connections are done, fill in any gaps in the through holes with putty or insulation (pro-
cured locally) to prevent small animals and insects from entering the unit from outside. (If any do get in, they
could cause short circuits in the terminal box.)
•
Outside the machine, separate the weak wiring (remote controller cord) and strong wiring (interunit,
ground, and other power wiring) at least 50 mm so that they do not pass through the same place together.
Proximity may cause electrical interference, malfunctions, and breakage.
