Mounting Tube Cable Routing
After the cable assemblies are made and wiring installed to the mounting tube back plate, route wiring
bundle as appropriate.
Use tie wraps to secure the cable assemblies and coax to the holes provided in the bottom of the connector
plate to provide strain relief for the cable assemblies. The cable shields should be grounded directly to a
lug mounted to one of the holes on the bottom of the connector plate, keeping the ground leads to a
maximum of 3 inches long.
2.6.2
Unit Insertion
Position the cam lock as shown below. The front lobe of the cam should be vertical. The cam lock
mechanism should be fully unscrewed (turned counter-clockwise). Slide the unit into the frame. Turn
clockwise and carefully tighten (15 in-lb max.) the cam lock mechanism using a 3/32" hex driver. The
unit will be pulled into the frame, securing the unit and connectors when fully engaged.
Do NOT
overtighten.
The back of the bezel must be flush to the mounting tube (within 0.020"). If the cam lock is
hard to turn or the unit does not seat fully, the unit is probably binding and the mounting tube should be
checked.
