Chassis Mount PC Board Assemblies
Any vertical, horizontal, or angled surface is
suitable for mounting the CBC-300-C,
CBC-300-C1, CBC-300-C2, or CBC-300-C3
control.
Follow these procedures to mount your control:
q 1. Determine the mounting location where the
control will be placed.
q 2. Layout the mounting hole dimensions and
drill holes and taps using a 4-40 tap.
Two options exist for mounting. The panel
can be drilled and tapped for mounting or
through holes can be used. (See Figure 2)
q 3. If the CBC-300-C1, CBC-300-C2 or
CBC-300-C3 controls are used, wire the
external potentiometers to the appropriate
terminal blocks as shown.
q 4. Place the faceplate over the PC board
assembly aligning the holes on the faceplate
with the holes on the PC board.
q 5. Using the 4-40 screws supplied, mount the
PC board and faceplate assembly to the
panel. Insure that the faceplate aligns
correctly and does not contact any of the
components on the PC board.
q 6. Tighten all four mounting screws securely if
the panel was drilled and tapped. Discard the
nuts supplied with the screws. If the panel
was drilled only, then use the nuts with the
screws to secure the control to the panel.
q 7. If the CBC-300-C or CBC-300-C2 was
used, insert the knob on the internal
potentiometer shaft.
q 8. Attach the switch setting label next to the
control as a reference for switch set up.
Note: Be careful not to pinch or crimp the
potentiometer wiring to prevent shorting to the
chassis or control components.
This completes the mounting of the control. The
unit is now ready for final wiring. Refer to the
wiring section for final wiring.
