Conduit Openings For The Ips Cabinet - Whelen Engineering Company IPS 400 Product Manual

5.4 Conduit Openings for the IPS Cabinet

The installer must punch entry holes in the IPS cabinet. The holes are typically made on the left side of the
cabinet, as shown in the drawing.
Note: The location of the holes, the size of the holes and the number of holes is left to the installers
discretion. However, the drawing shows the factory's recommendation. Following the factory
recommended hole pattern will ensure compatibility with future options or system expansion. Do not
try to line up the AC conduit with the AC outlet box in the cabinet.
Refer to the drawing below. Notice the 5" x 7" cross-hatched open area , 3" from the back wall and 5" from the
bottom shelf. Locate two holes in the 5" x 7" open area. Working from the inside of the cabinet, drill a pilot hole
for each of the holes. Open the top hole to 1 1/4" diameter and the bottom hole to 3/4" diameter.
The 1 1/4" hole is for the speaker conduit. The 3/4" hole is for the AC service and the antenna cable, if an
optional radio is installed. Run the speaker conduit to the 1 1/4" hole and the AC conduit to the 3/4" hole. The
use of "L" or "T" fittings is advised to simplify routing of speaker wires and the optional antenna cable.
Note: If the cabinet is in an area where it is exposed to water, the conduit fittings to the cabinet must be
properly sealed.
