12. WCC III INSTALLATION
Satellite Controller
Mounting in an Enclosure
The satellite controllers are designed to mount in any NEMA 1 or
NEMA 3 standard, six-inch deep, electrical enclosure. Typically,
this is a fi eld-mounted enclosure that contains transformers and
any accessory items required such as a binary input board, V-Out
Binary output board, control relays, etc. The best location for these
satellite panels is mounted on a wall in equipment or storage areas
or rooms at eye level near the controlled loads.
The satellite controllers may be ordered with or without the
NEMA type enclosures. If you order the satellite controller from
the factory without an enclosure, the SAT III and SAT 3C/D/F
dimensions as shown in Figure 12-13 and Figure 12-14 may be
helpful when selecting a suitable NEMA type enclosure.
The satellite controller must be mounted in an electrical enclosure.
If you do not order the satellite controller with an electrical
enclosure, you must provide your own electrical enclosure and
then provide and then install your own fused disconnect switch,
transformer, and terminal strip.
The size of the standard single SAT enclosure is designed to hold
only one satellite controller (or up to two SAT 3C/D/F controllers),
one fused disconnect switch, one transformer, one fi lter, and one
terminal strip which is normally about 15” x 15” x 6” deep with an
inter panel for mounting the SAT III controller, fuse block, 100VA
transformer, etc. The size of the standard dual SAT enclosure is
designed to hold two satellite controllers (or up to four SAT 3C/D/F
controllers), one fused disconnect switch, two transformers, two
fi lters, and two terminal strips is 30” x 18” x 6” deep with an inter
panel for mounting the two SAT III controllers, fuse block, 100VA
transformer, etc. If you install the satellite controller yourself,
make sure you leave room for wires that need to be connected to
the following terminals that are located on the sides of the SAT III
satellite controller (minimum recommended clearance is 2 inches):
You can also have both a SAT III controller and up to two SAT
3C/D/F controllers in the same dual enclosure.
