Wiring Considerations
The OE325-01 Zone Controller Expansion Module connects to the
VAV/Zone Controller Actuator Package by means of a modular cable
provided with the expansion module. Power is supplied to the Zone
Controller Expansion Module by means of this modular cable. Screw
terminals are provided for connection of fi eld wiring to the relay and
analog outputs. The Expansion Module is used to supply extra relays
and/or analog outputs to control fan and heating functions for the VAV/
Zone Controller Actuator Package.
The OE325-01 Zone Controller Expansion Module is always shipped
loose for fi eld mounting by others. Be careful not to damage the elec-
tronic components when mounting the controller. Remove the controller
from its snap track mount. Mark the control enclosure base using the snap
track as a template. Drill pilot holes in the enclosure base and secure the
snap track to it using sheet metal screws. Do not allow metal shavings to
fall onto the circuit board. Re-attach the controller to the snap track. Be
sure the mounting location is close enough to the VAV/Zone Controller
Actuator Package so that the supplied modular cable will reach from it
to the Zone Controller Expansion Module.
Warning: The 4 relay outputs available on the OE325-01
Expansion Module are each rated for 1 Amp. @ 24
VAC. If your device load exceeds these limits, a
pilot duty relay (by others) must be used in the
circuit.
The wiring consideration information previously outlined for the VAV/
Zone Controller Actuator Package should be followed when wiring the
OE325-01 Zone Controller Expansion Module.
