Locate and remove chassis knockouts
The WEB/CP-202-XPR or WEB/CP-602-XPR has six (6) wiring knockouts on the back of the plastic chassis (see Fig. 4):
• Five (5) round, 0.945 in. (24 mm) diameter, for general wiring of controller terminals and I/O points.
• One (1) oval, 0.46 in. (11.7 mm) wide x 1.25 in. (31.7 mm) high, for wiring 24V input power and ground.
Fig. 4. Wiring knockout details.
NOTE: In addition to these rear knockouts, there are two wiring holes, 0.845 in. (21.5 mm) for general wiring—one on the top
side, one on the bottom side. The top hole has an associated “U-shaped knockout” atop the right cover. Also, an
additional wiring hole is at the bottom 0.865 in. (22 mm), available for wiring 24V input power and ground. Usage of
wiring knockouts and holes will vary by installation.
Remove the appropriate knockouts, as needed, before mounting to the wall. Note that the shielded 24V power input wiring area
has a hole on the bottom side, as well as an oval-shaped knockout on the rear of the chassis. If necessary, install any conduit or
cable clamps to knockout holes.
