Belt Guards; Electrical Connections - Greenheck BIDW Installation, Operation And Maintenance Manual

Belt Guards

Greenheck offers
various types of
customized belt guards
dependent upon fan
model, arrangement
and motor position.
Motor position is
determined from the
drive side.
The various types of belt guards are shown in
illustrations. If the guard is not purchased from
Greenheck, they must be supplied by the installer
or owner.

Motor position and fan rotation are
determined from drive side
If the belt guard is not factory mounted or was not
supplied by manufacturer, then it must be field mounted.
Brackets and mounting hardware are the responsibility
of the installer. The figures below illustrate suggested
attachment points for belt guard mounting bracket
locations. These locations vary with motor mounting
position, arrangement, and fan type. The bearing
supports and fan structure are used in most instances
and when the motor is not mounted to the fan itself, a
bracket should also be located near it. This information
is intended only as a guide and actual field conditions
may dictate another mounting location for the guard
brackets. Refer to local codes for securing guarding.

Electrical Connections

Before electrical connections are made, the supply
voltage, phase and ampere capacity must be checked
for compatibility with the fan motor. In addition, the
supply wiring must be properly fused and conform to
local and national electrical codes. If the unit is supplied
with a safety disconnect switch, ensure proper wiring
to the fan motor. Be sure the disconnect is switched to
the "OFF" position before connecting supply wires. If
no disconnect is supplied, ensure the supply wire is not
live before connection. Supply wires are then connected
to the optional safety disconnect switch (if supplied) or
motor.
