2. INSTALLATION ACCESSORY
WIRED CONTROLLER INSTALLATION PRECAUTION
1. This manual provides the wired controller installation method. Refer
to the wiring diagram in this installation manual to wire the wired
controller with the indoor unit.
2. The wired controller works in a low voltage loop circuit. Do not
connect directly to 208/230V and 460V. Do not wire this kind of wire
into a loop. Wiring clearance between the configured tubes should
range 11.81−19.69 inches (30−50 cm) or above.
3. The shielded wire of the wired controller must be properly grounded.
4. Upon finish the wire controller connection, do not employed
tramegger to detect the insulation.
