CONTROL BOX INSTALLATION
The control box can be mounted either on
the standard travel carriage or on a separate

in the input cable assembly.
To install the control box on the standard
travel carriage, use mounting kit T14469 and
perform the following steps. Also refer to
Figure A.2.
1. Align the mounting holes in adapter
plate M-13945 to the holes in the
travel carriage.
2. Install four hex head screws through
the adapter plate and into the travel
carriage.
3. Secure the control box to the adapter
plate with four lock washers and four
bolts, two from the bottom and two
from the back.
Before mounting the control box onto a
fixture, you must provide mounting holes in
the fixture per the measurements provided
in Figure A.3 or dimension print S16717.
When placing the mounting holes, ensure
the controls and meters are convenient to
the operator.
