NOTICE
Precautions when laying power wiring:
▪ Do NOT connect wiring of different thicknesses to the
power terminal block (slack in the power wiring may
cause abnormal heat).
▪ When connecting wiring which is the same thickness,
do as shown in the figure above.
▪ 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
damage the head and make proper tightening
impossible.
▪ Over-tightening the terminal screws may break them.
NOTICE
▪ Follow the wiring diagram (delivered with the unit,
located at the inside of the service cover).
▪ For instructions on how to connect the optional
equipment, see the installation manual delivered with
the optional equipment.
▪ Make sure the electrical wiring does NOT obstruct
proper reattachment of the service cover.
It is important to keep the power supply and the transmission wiring
separated from each other. In order to avoid any electrical
interference the distance between both wirings should ALWAYS be
at least 50 mm.
NOTICE
Be sure to keep the power line and transmission line apart
from each other. Transmission wiring and power supply
wiring may cross, but may NOT run parallel.
