2. Electrical Requirements
Wiring Diagram
Connect the charger to a single phase 120/240 volt, bonded neutral power source. All wire must be sized in
accordance with the National Electric Code.
Electric vehicle charging stations must be equipped
with an internal Ground Monitor/Interrupter circuit
(GMI circuit). For the GMI circuit to function, a
reference to ground must be made through a main
bonding jumper or system bonding jumper (located
where the neutral connection is established and
bonded to ground). Without the neutral to ground
connection, GMI protection is not possible, and the
charger will be inoperable.
If you have an electrical system without a neutral you
must upgrade your electrical service from the utility
or provide a separately derived system to effectively
power and protect the electric vehicle charger.

4. Installation
Site Selection
The charger should be installed in a location suitable for the 25-foot output cable to extend to the electric vehicle’s
charging port and which allows sufcient space for output cable storage in the cable hanger. The top of the wall
mount bracket is recommended to be installed at a height of 50 inches above the nished oor (check local codes).
If installing the NEMA 14-50 plug version, ensure the charger location can accommodate a NEMA 14-50 receptacle.
The NEMA 14-50 receptacle should be located no less than 24-26 inches from the ground. Consideration should be
made to the NEMA 14-50 receptacle orientation (ground terminal in the upward ‘12 o’clock position’ or downward
‘6 o’clock position’). The NEMA 14-50 receptacle orientation will determine the NEMA 14-50 input cord’s installation
aesthetics.
Ensure the height of the wall mount bracket and the NEMA 14-50 receptacle are coordinated so the NEMA 14-
50 plug seats into the NEMA 14-50 receptacle without cable tension or stress. If installing the hardwired version,
ensure that the selected charger location is within reach of the site rated junction box using the supplied 3 feet of
manufactured cable.

Wall Preparation
1. Locate and remove the top mounting screw from the charger using the supplied Allen wrench.
2. Remove the wall mount bracket from the charger by applying downward pressure on the wall mount
bracket until the charger mounting screws unseat from the wall mount bracket keyhole slots.
3. Store the charger and mounting screw in a safe place to avoid damage or loss.
4. At the selected location, mark the center of the stud and place the wall-mount bracket on the wall.
5. Using a level, ensure the wall-mount bracket is in an upright level position. Align center mounting holes with
the center of the stud and mark the wall-mounting screws holes.
6. Use mounting holes to secure the bracket to the wall using appropriate site-specic fasteners.

6
Wall Mounting (NEMA 14-50 Version)
1. Locate the 3 mounting screws on the rear of the charger. Position them into the corresponding keyhole slots on
the wall mount bracket. Slide downward until fully seated.
2. Reinstall the top mounting screw using the supplied Allen wrench to secure the charger. The charger should
feel secure after it is fully seated. If the charger can be easily moved then remove the charger, slightly tighten
the three mounting screws on the rear of the charger and replace the charger on the bracket.
3. Insert the NEMA 14-50 plug into the NEMA 14-50 receptacle. Ensure that the plug is fully seated into
the receptacle.

7
Wall Mounting (Hardwired Version)
The hardwired version of the SemaConnect Series 4 EV Home Charger is manufactured with 3 feet of cable that
has been listed by a Nationally Recognized Testing Laboratory (NRTL) to the appropriate UL standards for the
specied ampere ratings.
Ensure that the selected charger location is within reach of the site rated junction box using the supplied 3 feet of
manufactured cable.
1. To sufciently attach and tighten the 3/4” Liquid Tight Flexible Metal Conduit (LFMC) to the charger, the
bottom plate must be removed. Place the charger face down on a safe surface to avoid damage. Grasp the
outside of the charger with both hands, position thumbs on the inner edge of the protective lower cover and
apply downward pressure on the cover to unseat it from the charging station. Store protective cover in a safe
place to avoid damage or loss.
2. Measure and cut 3/4” LFMC to sufcient length between the charger and site rated junction box. Attach and
tighten the 3/4“ LFMC to the charger using the manufacturer-supplied 3/4“ LFMC connector. Re-install the
protective cover.
3. Locate the 3 mounting screws on the rear of the charger. Position them into the corresponding keyhole slots
on the wall mount bracket. Slide downward until fully seated.
4. Reinstall the top mounting screw using the supplied Allen wrench to secure the charger. The charger should
feel secure after it is fully seated. If the charger can be easily moved then remove the charger, slightly
tighten the 3 mounting screws on the rear of the charger and replace the charger on the bracket.
5. Attach and tighten the 3/4“ LFMC to the site rated junction box. Connect the supplied black and red
conductors to the 240-volt supply (ungrounded) conductors, and the supplied green conductor to the
grounding conductor.
Install SemaConnect Series 4 EV Home Charger in accordance with all State, Local, and National Electric Codes.
