Wiring Connectors
The 1400 includes compression-type liquid-tight connectors for
routing wires into the enclosure. To use these connectors, turn
them counter-clockwise to loosen (or open-up) the compression
washer. Insert all cables through the two connectors. When finished
turn them clockwise to secure and seal the 1400 from the outside
environment. If you don't have enough cables to obtain a snug fit
you can insert a small piece of soft PVC insulation or rubber tubing
to take up the extra space.
