Controller Enclosure Wiring
1. Wire low voltage connections on the low
voltage side of the enclosure, see Figure 10.
2. Wire high voltage connections on the high
voltage side of the enclosure, see Figure 10.
3. Use the internal labels (low voltage - yellow, high
voltage - orange) to identify connection points.
4. Use the cable ties provided to secure internal
wiring to the controller frame. See Figure
10 for recommended cable tie locations and
Table 5 for connection point functions.
5. Pass cables through the appropriately labeled
strain relief ports. It may be necessary to
pierce the strain relief grommet prior to
passing the cables through it.
