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 exible 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 oor 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) o 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 o input power to the EVSE at the circuit breaker panel prior to plugging it in or
wiring it to the service lines. Likewise, turn o the circuit breaker prior to unplugging it or disconnecting the unit
from the service lines.
