The controller enclosure is constructed of a plastic base
plate and a plastic factory-snap-on cover. The cover does
not need to be removed from the base plate for either
mounting or wiring. Removable terminal blocks are used
for all wiring connections, which allow the controller to be
wired before or after mounting.
The controller can be mounted in any orientation.
Ventilation openings are designed into the cover to allow
proper heat dissipation, regardless of the mounting
orientation.
NOTE: The controller must be mounted in a position that
allows clearance for wiring, servicing, and
removal.
NOTE: For complete mounting information, refer to the
Installation Instructions, form 62-0310.
PVBXXXXAS Mounting (Controllers with
actuators)
The PVBXXXXAS controllers include the direct-coupled
actuator with Declutch mechanism, which is shipped
hard-wired to the controller (using digital outputs 7 and
8).
The actuator mounts directly onto the VAV box damper
shaft and has up to 44 lb-in. (5 Nm) torque, 90-degree
stroke, and 90 second timing at 60 Hz. The actuator is
suitable for mounting onto a 3/8 to 1/2 in. (10 to 13 mm)
square or round VAV box damper shaft. The minimum VAV
box damper shaft length is 1-9/16 in. (40 mm).
After the actuator is mounted to the damper shaft, the
controller mounts to a panel by using four No. 6 or No. 8
machine or sheet metal screws inserted through the
corners of the base plate.
