Installation
This installation and operations manual has been
arranged for the systematic installation and startup
of your Warner electric clutch-brake control system.
To achieve the best possible results, check off each
completed step in the space provided before pro-
ceeding to the next step.
Sample
Check off each step when completed.
Refer to Figure 1, Page 6, for dimensional data and
mounting hole locations.
1. Pick a suitable location for mounting the
control based on application requirements.
2. Open the control by pulling up on the two
plastic pin connectors that hold the main
board assembly to the lower chassis
assembly.
3. Using the dimensional data in Figure 1, Page
6, mark and drill four (4) mounting holes using
a #21 drill. Tap the four (4) holes using a
#10-32 tap.
4. Start the top two (2) screws in the mounting
holes but do not tighten. Leave sufficient
space between the mounting surface and the
screw heads to mount the control.
5. Carefully slide the large slots of the top two
(2) mounting screw holes in the control
chassis over the heads of the mounting screws
already installed. Slide the control all the way
down on the screws.
Note: If the slots will not fit over the screw
heads, the two mounting screws must
be turned out (CCW) to increase
clearance before the control can be
mounted.
6. With the control chassis held firmly in place,
start the bottom two mounting screws into
their mounting holes. The ribbon connector
may have to be disconnected from the upper
terminal board to start the lower left hand
screw. Do not tighten the screws yet.
7. Line up the control squarely and tighten all
four mounting screws securely. Reconnect the
ribbon connector.
Note: If the control is mounted inside a control
enclosure and wires enter the control without
conduit, use plastic bushings to protect wires
entering the conduit entrance holes.
This completes the mounting installation of the
CBC-750 control chassis. Proceed to the wiring
section for control wiring information.
