Figure 3.10 – Type 1 Base Plate Mounting Orientations

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).
