Wiring Connections
1. High and low voltage wires should be led through
different rubber rings of the electric box cover.
2. To avoid communication errors, maintain as much
separation as possible between the power and control
wiring.
3. High and low voltage wires should be secured
separately. Secure the former ones with large clamps
and the latter ones with small clamps.
4. Use screws to tighten high and low voltage wiring on
the terminal board. Improper connection may create a
fire hazard.
5. Ground the units by connecting the ground wire.
