Wiring Instructions
Refer to Figure 3 and Figure 4 for connectors’ location.
1. All field connections to be made with insulated copper wire, either solid or
stranded. Tighten all screw terminals to 4.5 lb-in (0.5 Nm).
Strip length = ¼ in (7 mm).
DO NOT
pre-treat wire with solder.
2.
Terminals Earth Ground, L2(V-), L1(V+) on J2 (Main Board) and
terminals 1-6 on J3-J4 (Options Board):
Use AWG #12-18 wire, 600 volt,
60
°
C. Connect only one wire to each terminal.
3.
Terminals EN, AK, R, CM, S+, S-, P-, P+, P1-, P1+ on J1 (Main Board)
and ter, - (Options Board):
Use AWG #12-22 wire, 150 volt, 60
°
C.
If using AWG #20 or smaller wire, up to two wires may be connected to each
terminal. If using AWG #18 or larger wire, only one wire may be connected
to each terminal.
4. Install conduit hubs to the enclosure cable input ports. To maintain NEMA
4X rating use only UL/CSA watertight conduit hubs.
5. Feed all wires through the enclosure cable input ports.
6. Remove one connector at a time from the headers and connect the wires to
the connector.
7. After wiring a connector, insert it back into the header.
