INSTALLATION
Service Wiring Requirements
Prior to mounting, consult a certied electrician about an electrical source that can support the
following:
The Circuit must be a DEDICATED CIRCUIT 208-240 VAC, 50-60 Hz, Single Phase.
Requirements govern that only 80% of the circuit rated load may be utilized. Use the following
Maximum Amperage Settings depending on the circuit breaker rating:
Circuit Rating Maximum Charging Station Output
50A 40A
40A 32A
30A 24A
20A 16A
• A Double Pole Circuit Breaker of the circuit rating must be used.
• The Charging Stations can connect a Standard NEMA 6-50 or 14-50 Receptacle, or the unit can
be hardwired.
• A cable with a dedicated grounding conductor connected to the equipment ground terminal
block must be used.
CAUTION: The service wiring in this section are specic to North America only. Before installing
the Charging Station, identify the type of utility service connection onsite. If unsure about the
type of connection available at the service panel, contact your utility service provider.
WARNING: Disconnect the power supply to the charging station before installing, adjusting, or
repairing the charging. Failure to do so may result in physical injury or damage to the power
supply system and the charging station.

5
Install Charging Station
Prior to mounting, determine the location of an acceptable mounting support:
• The charging station must be anchored into a mounting support such as a 2” x 4” stud or a
solid concrete wall. DO NOT mount this unit directly to a stucco/drywall/wall board.
• Mount the unit between 24 inches (0.6 m) and 48 inches (1.2 m) from the ground. The NEMA
outlet should be located more than 18” above the ground or as dened by applicable, local
electrical safety codes and standards.
Mounting Screw Recommendations:
• For nished walls supported by wood studs, use #14 or M6 tapping screws. (Included).
• For masonry walls, use M6 mechanical screws. (Commercially available)
Parts and Tools required for installation:

1. Separate the front and back pieces of the mounting bracket by pushing down on the notch.
2. Secure the back piece of the mounting bracket to the wall or other suitable structure using the
Robertson-head screws.
3. Attach the front piece of the mounting bracket to the back of the charging station using the
Socket-cap screws and washers. Ensure the top of the mounting bracket is matched with the top
of the charging station.

7
4. Mount the charger on the wall by securing the front piece of the mounting bracket to the back
piece. Align the notches and press down to secure the charger.
5. Position the Side Cover over the mounting bracket. Use the Side Cover screws to secure the
two pieces together.
6. Plug in the power cord to the NEMA 14-50 or NEMA 6-50 Wall Outlet/Receptacle.

8
Adjust Maximum Output Current DIP Switches
Note: Only change the Maximum Current DIP Switch settings if your local electrical code
requires a physical switch for compliance. If the building code does not require a physical switch
use see “Set Amperage” on page 19.
To set the Maximum Output Current through the DIP Switches:
1. Ensure the unit is unplugged. Ensure Charging Station is facing up on a at surface.
Remove the plastic protective cover.
2. Use a Phillips Head screwdriver to remove the 6 screws on the front of Alpha. Carefully place
the front cover to the side without damaging the communication cable.
3. Locate the DIP Switches on the PCB. The DIP Switch is a 3-position switch on the secondary
circuit board, located behind the USB cable.

Optional Hardwire Connection
CAUTION: Do Not attempt to hardwire the Alpha unless you are qualied to do so. If you are not
qualied, contact a licensed electrician.
1. Choose a copper wire conduit in accordance with all applicable, local, and electrical safety
codes and standards.
2. Choose a terminal ring with the following characteristics:
• Recommended Wire Strip length: 8mm (0.32”)
• Width of the terminal block opening: 10.2mm (0.41”)
3. Using the appropriate tool, clamp the wire terminal to the copper wire. For non-insulated
terminals, use a heat shrink tube to cover the non-insulated portion of the terminal.
4. Remove the plastic protective cover from the front of Alpha.
5. Use a Phillips Head screwdriver to remove the 6 screws on the front of alpha. Carefully place
the front cover to the side without damaging the communication cable.
6. With the front cover placed to the side, use a Philips Head screwdriver to release terminal
screws of the 6-50 or 14-50 Plug cable. Loosen the Strain Relief Fitting and remove the Plug.
Remove the Strain Relief connector.
7. Insert the wire end passing through the conduit and insert them into the input wiring hole.
(Use Red wire for L1, Black wire for L2, Green wire for G). Attach the wire terminal to the
corresponding terminal block. Use the following wire and torque force when connecting to
input terminal block:
Terminal Conductor Screw Rating Torque
L1 8 AWG M4 75C copper wire max 1.8Nm | 16
LBF.IN
L2 8 AWG M4 75C copper wire max 1.8Nm | 16
