Factory Pre-Wired Terminal Box (Optional)
BAC offers an optional terminal box with factory pre-wiring for Series 3000 Cooling
Towers. When this option is ordered, the cooling tower’s fan motor(s) and vibration cutout
switch are wired at the factory (through flexible conduit and the mechanical equipment
support) and terminated on the outside face of the BAC unit in a clearly marked, 304
Stainless Steel, NEMA 3R terminal box (see
Figure 33
for the exterior location of the box
on the cooling tower).
The box includes a cover plate, which once removed reveals an easy-to-follow wiring
diagram and modular terminal blocks. Remove the cover plate, and install the collar (ships
loose in the cooling tower’s basin) which has prepunched conduit holes. Wiring from the
terminal blocks to the unit controls is sized, provided and installed by others. After the
controls are wired, reinstall the cover plate on the terminal box.
