LCR 6600 RFN Load Control Switch (Brazil)
Mounting the LCR 6600 RFN
Perform the following steps to mount the LCR:
1. Determine which knockout(s) are to be used.
The LCR 6600 RFN contains five knockouts for
input and load wiring:
•
Knockouts A and D – Enters the Class 2 wiring
compartment (Class 1 if the divider is not
present). These knockouts are for 1/2 inch
(1.25 cm) conduit.
•
Knockouts B, C and E – Enters the Class 1
wiring compartment. Knockout B is for 3/4
inch (1.905 cm) conduit. Knockouts C and E
are for 1/2 inch (1.25 cm) conduit.
2. Remove the knockout prior to mounting by
using a drill and a conduit-style step drill bit.
The dimple in the center of the knockout allows
you to accurately position the step-drill bit in
the center of the knockout for a clean hole.
The knockout may also be removed by inserting a
screwdriver into the knockout slot at several
points and prying it out. Do not hit the knockout
directly, as this may damage the case.
For added flexibility, the LCR enclosure provides
two side-entry access holes, D and E.
Per the manufacturer’s instructions, install a
conduit fitting onto the LCR enclosure. A small
bead of weather-proof silicone should be used to
seal the conduit fitting to the face of the enclosure.
See the Cooper Crouse-Hinds Web site for UL
approved conduit fittings:
3. Mount the LCR 6600 RFN at the desired
mounting location, which is preferably a flat,
non-vibrating surface. Tightening the screws on
an irregular surface may distort the mounting
tabs. This can cause the tabs to break or defeat
the rain-tight seal.
For best reception, mount the LCR four feet or
higher above the ground, on the exterior of a
structure, and away from metal surfaces.
Ensure that the front door has room to open at
least 90 degrees. The minimum required
clearance is 8 inches (20.3 cm) in front of the
mounting surface.
The LCR provides three pre-drilled mounting tabs.
Cooper Power Systems recommends #10 pan
head screws for mounting the LCR. The diameter
of the mounting holes is 1/4 inches (0.635 cm).
For a rain-tight rating, mount the LCR so that
Knockouts A, B and C are located at the bottom
of the unit facing the ground.
4. Perform the LCR installation and wiring
