Warner Electric PCBC-500 Clutch_Brake Coupling - Manual (Page 21)

Step 1 Fasten bracket (1) to the clutch or brake with
one No. 10-32 hex. washer head screw and
washer (2). The square pro jec tion on the
clutch or brake between the terminals is to be
assembled into the square hole in the bracket.
The bracket flange is installed toward the back
of the unit. (Figure 1)
Step 2 Assemble a 1/2" flexible conduit fitting into the
desired end of the conduit box (3). If
the grounding nut on this conduit fitting is
tightened after the conduit box is installed on
the magnet or field, avoid using excessive
tapping force, which could damage the
mounting. (Step 6)
Step 3 Mount conduit box (3) to the bracket (1).
The conduit box flange must be toward the
back of the clutch or brake. Secure the box
with two No.10-32 hex. washer head screws
(4). (Figure 2)
Step 4 Snap the two rubber grommets (6) into two
square holes in the bottom of the conduit box.
The grommet crowns should be in the box
and the rubber flanges should be on both
sides of the metal floor. (Figure 3)
Figure 1
Step 5 Push two terminal spacers (7) through the
grommets with the spacer flanged ends inside
the conduit box. (See Figure 3)
Step 6 Connect electric supply cable to the fitting
installed on the conduit box. Use D.C.
supply only.
Rigid conduit must not be
connected directly to the
box. A minimum of 12" of flexible cable
must be used. It is rec om mended that
flexible "UL" listed liquid-tight, metallic or
non-metallic conduit, meeting local
codes, be used with ap pro pri ate fittings.
Flexible cable is required to prevent side
loading of bearing on bearing mounted
clutches and brakes and possible
deformation of the conduit box or
components during assembly.
Step 7 Press protective plug (5) into the unused
conduit hole in the box.
Step 8 Slide one rubber cap (8) onto each of the two
supply conductors, small end first. Connect
the two supply con duc tors (with rubber caps)
to the magnet or field
terminals using two No. 6 or No. 8 screws
(11). Use wire retaining ring terminals
supplied with the clutch or brake terminal
ac ces sory. The stripped wires may be
wrapped around the screw between the wire
terminal ring and the screw head or other ring
type terminals such as "AMP" may be used.
The screws are then assembled through the
terminal spacers (7) and threaded into the
clutch or brake terminals.
