HCS Installation and Operation Manual
Mounting procedures
Determine the wall mounting position of the EVSE:
•
On the hardwired HCS, the three service conductors are shielded by 3 ft (1 m) of flexible conduit at the bottom of
the unit. The EVSE must be positioned such that this conduit can reach a nearby junction box.
•
On the plug-in HCS, the NEMA plug head is connected by 12 in (305 mm) of cable (including the plug head) to
the bottom side of the EVSE. The plug-in HCS must be positioned such that this plug can safely be inserted into a
wall-mounted NEMA socket. Do not allow the power supply cord to contact the floor when plugged into the outlet.
•
Position the bottom of the EVSE at a comfortable height and at least 18" (45.7 cm) above the ground for indoor
installations and 24" (61 cm) off the ground for outdoor installations. Ensure that the LEDs on the front panel of
the EVSE can clearly be seen by the user of the device.
•
The HCS EVSE has two vertically aligned mounting holes spaced 17" (43.2 cm) apart, one each on the enclosure
top and bottom. Use a ruler or template to mark hole locations on the mounting surface.
WARNING: For safety, always turn off input power to the EVSE at the circuit breaker panel prior to plugging it in or
wiring it to the service lines. Likewise, turn off the circuit breaker prior to unplugging it or disconnecting the unit
from the service lines.
