Single or Dual Pole-Mounting The 3704 EVSE
A pole-mount configuration uses a 62.5” mounting pole that is pre-drilled so one or two 3704 EVSEs can be mounted to it.
There is also an access cutout in the pole, to facilitate wiring through the center (Figure 9A). In order to ensure maximum
stability, be sure to mount the pole to a flat surface, or use washers when mounting to add stability.
NOTE – Conduit can enter through the center of the mounting pole and allow wiring to pass through to
the EVSE(s) via the access holes in the pole, which aligns with the access holes in the EVSE when
properly mounted.
Before mounting the EVSE(s) to the pole, ensure the wiring for the EVSE(s) is routed through the center
of the pole and accessible via the access cutout. See the Wiring the EVSE section for connections.
With the pole securely mounted (Figure 9B) – level and plumb on all sides – and the front cover
removed from the EVSE(s), the mounting holes and wire access holes on each EVSE will align with the
pre-drilled holes on the pole. Ensure the knockout plug is removed from between the two bottom
mounting holes.
1.
Using four supplied #10 screws and lock washers, attach the EVSE to the side of the pole using the
pole’s mounting holes. Ensure the Pole’s and EVSE’s access holes align. Refer to Figure 8A for
mounting-screw hole locations inside the EVSE.
2.
Repeat Step 1 for the other EVSE on the opposite side of the pole, if applicable.
3.
Pass the wiring coming up through the center of the pole through the appropriate access holes in the pole and
EVSE(s).
4.
Inside the access cutout hole, locate the ground bar. Attach the ground cable originating from the breaker panel to
this ground bar, and then add a ground wire between it and the ground bar inside the 3704. See Figure 10A.
See the Wiring the EVSE section for connections.
