Step 1 Fasten bracket (1) to the clutch or brake
with one No. 10-32 hex. washer head screw
and washer (2). The square projection 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.
(See 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 in -
stalled on the magnet or field, avoid using
excessive tap ping force, which could dam-
age the mounting. (Step 6)
Step 3 Mount conduit box (3) to the bracket (1).
The con duit 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). (See Figure 2)
Step 4 Snap the two rubber grommets (6) into two
square holes in the bottom of the conduit
box. The grom met crowns should be in the
box and the rubber flanges should be on
both sides of the metal floor. (See Figure 3)

Rigid conduit must not be con nect ed
directly to the box. A minimum of 12" of flexible
cable must be used. It is recommended that
flexible "UL" listed liquid-tight, me tal lic or
non-metallic conduit, meet ing local codes, be used
with appropriate fit tings. Flexible cable is required
to prevent side loading of bearing on bear ing
mounted clutches and brakes and possible
de for ma tion of the conduit box or com po nents
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 ter mi nals
using two No. 6 or No. 8 screws (11). Use
wire re tain ing ring terminals supplied with
the clutch or brake terminal accessory. 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.
Step 5 Push two terminal spacers (7) through the
grom mets 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.
