CAL Controls 3300 Application Manual page 3

Insert the Nylon Screw into the 3mm diameter hole
at the bottom left hand corner of the 3300 / 9300 /
9400 / 9500 board.
Place spacer over Nylon screw thread.
Screw the Nylon Full Nut onto the screw.
Do not overtighten as this will damage the screw
thread.
Plug the 5-way female connector on the Comms
Board into the 5-way male connector on the
Controller board ensuring that connectors are all in
alignment. At the same time ensure the hole in the
Comms board fits over the screw thread.
Screw the Brass Half Nut onto the Comms board.
Do not overtighten but ensure it's tight enough to
stop the board from moving.
Cut the top of the screw thread so that it is level
with the top of the Brass Half Nut.

Now you are ready to refit the Controller into
its case. To do this carefully slide the PCB into
the case aligning it with the connector arms
at the rear, and then press the bezel
assembly firmly into the sleeve until the latch
clicks in order to compress the gasket and
seal to NEMA4/IP66.
