Wiring
CAUTION
Electrical Interference Hazard.
Running cable near line voltage can interfere with
panel operation.
Run cable connecting AZ terminals at least
12 in. from line voltage wiring.
IMPORTANT
Be sure AZ1 and AZ2 wires do not cross and are a
minimum of 12 in. from any line voltage wiring. If not
possible, use shielded cable for AZ1 and AZ2 wires.
NOTE:
Only two wires are required to connect the TAZ-4H
panels to the main HZ432 panel. If more than one
TAZ-4H is used, each TAZ-4H can be wired in a
daisy chain or parallel to each other, connecting the
AZ1 and AZ2 terminals between panels. Each AZ1
and AZ2 terminal can fit two wires to simplify daisy
chain wiring.
