Connecting Wiring
Route network and power cabling into the electrical enclosure using suitable
conduit fittings, bushings, or wire glands. Once the cabling has been brought into
the electrical enclosure, leave a service loop of <6 inches (15cm) of cable to
simplify wiring the Type 1 Base Plate. Dress the cables using tie wraps or tape to
ensure that the cabling is not compressed or caught when the base plate is
screwed into place.
Strip the cable jacket and wire conductors. The base plate screw terminals will
accept 26AWG (0.4mm) to 12AWG (2.2mm) wire, which should be stripped to a
length of 0.32” (8mm). Although not required, it may be useful to use a soldering
iron to tin the stripped lengths of any stranded wires to prevent fraying and
inadvertent contact with adjactent terminals. The screw terminal blocks on the
rear panel of the Type 1 Base Plate are color coded to simplify wiring. The color
coding scheme is shown below. The optimum tightening torque for the Type 1
Base Plate screw terminals is 4 lbs. in. (0.5Nm) maximum. The ideal screwdriver
tip width is 0.125” (3mm).
