Terminal Connections

Figure 15 Wire-Strip Lengths

All wire connections are made through the ¾ inch (1.9 cm) NPT openings in the Base Housing to the Terminal Block. The Terminal Block is located in the Base Housing Assembly and accepts 14 AWG (2.08 mm2) to 22 AWG (0.33 mm2) stranded or solid-core wire. Each wire should be stripped as shown in the figure above.

To connect the wire to the Terminal Block, insert the conductor into the connection space and tighten the corresponding screw terminal.
