EXCEL 10 W7753A UNIT VENTILATOR CONTROLLER
95-7520—02 2
INSTALLATION
Mount the W7753A in a position that allows clearance for
wiring, servicing and controller removal. Avoid mounting the
W7753A in areas where acid fumes or other deteriorating
vapors can attack the metal parts of the controller, or in areas
where escaping gas or other explosive vapors are present.
See Fig. 2 for mounting dimensions.
The controller enclosure on the W7753A is constructed of a
sheet metal housing and a plastic factory snap-on cover. The
controller mounts using two screws inserted through the
plastic cover. Use the screws appropriate for the mounting
surface. The W7753A can be mounted in any orientation.
Ventilation openings were designed into the cover to allow
proper heat dissipation regardless of the mounting orientation.
The W7753A can also be mounted using DIN rail (obtain
locally). If using DIN rail also purchase from Augat Inc. part
number 2TK2D DIN rail (adapter) two each (See Fig. 3).
