Precaution for the installation of the wired controller

1. This manual provides the installation method for the wired controller. Please refer to the wiring diagram in this installation manual to wire the wired controller with the indoor unit.
2. The wired controller uses extra-low voltage (ELV) only. DO NOT connect to low voltage 230VAC circuits or wiring as damage to wired controller will result. Maintain correct separations between ELV wiring and other 230VAC mains wiring.
3. The shielded wire of the wired controller must be properly grounded, see wiring diagram.
4. Upon finalising the wired controller connection, do not use an ohmmegger test to check the insulation.
