WARNING: Disconnect the power supply before installing, adjusting,
or repairing the charger. Failure to do so may result in physical injury
or damage to the power supply system and the charger.
2. Installation planning and service wiring
• Prior to mounting, locate an available electrical source that can support the following
input requirements for the charger per local Electrical Safety Code requirements:
»40A maximum output seing (default factory seing): a DEDICATED CIRCUIT rated
for 50A; 208-240 VAC, 50-60 Hz, Single Phase must be used.
»32A maximum output seing (optional seing): a DEDICATED CIRCUIT rated for 40A;
208-240 VAC, 50-60 Hz, Single Phase must be used.
»24A maximum output seing (optional seing): a DEDICATED CIRCUIT rated for 30A;
208-240 VAC, 50-60 Hz, Single Phase must be used.
»16A maximum output seing (optional seing): a DEDICATED CIRCUIT rated for 20A;
208-240 VAC, 50-60 Hz, Single Phase must be used.
• A Double Pole Circuit Breaker of the circuit rating must be used.
• The charger has built-in GFCI protection. Additional GFCI protection upstream of the
charger is not necessary. In locations where GFCI at the outlet is mandated by code, the
charger will not experience negative eects.
• The charger can connect to a Standard NEMA 14-50 receptacle, or the unit can be
hardwired.
2.2 Grounding instructions
The charger must implement equipment grounding through a permanent wiring system or
an equipment grounding conductor. Use a cable with a dedicated grounding conductor
connected to the equipment ground terminal block.
CAUTION: To reduce the risk of re, connect only to a circuit provided
with the minimum branch circuit overcurrent protection requirements
in accordance with the National Electrical Code ANSI/NFPA 7- and
the Canadian Electrical Safety Code, Part 1, C22.1. If you are unsure if
the circuit meets these requirements, consult a licensed electrician.
2.1 Electrical source requirements

3. Adjustable maximum current output
The Ivy Home Smart EV Charger features the ability to adjust the maximum charging station
current output to support 50A, 40A, 30A, or 20A dedicated circuit ratings as follows:
Circuit Rating Maximum Charging Station Output
50A 40A (9.6 kW)
40A 32A (7.68 kW)
30A 24A (5.76 kW)
20A 16A (3.84 kW)
• The charger default factory maximum current output seing is 40A (9.6 kW) for use with a
50A Circuit Rating.
• 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, hence the
higher Circuit Ratings Requirement relative to maximum charging station output.
To adjust the maximum current output seing:
1. Remove the front cover by removing the 4 screws at each corner of the charging station.
Use a 5/32” (M4) Allen key to remove the screws.
3.1 Adjust maximum current output

12
2. With the front cover placed to the side, locate the DIP switch on the charging station
circuit board. The DIP switch is a 4-position switch on the main circuit board, located
directly to the le of the LED.
UP DOWN
WARNING: Do not touch live electrical parts. Disconnect the power
supply to the charging station before adjusting the DIP switches.
Failure to do so may result in physical injury or damage to the power
supply system and the charging station.
UP UP
CAUTION: The LED pipe is aached to the front cover. When the
front cover is removed, place it on a at surface facedown to avoid
damage to the LED pipe.

4. Installation
Prior to mounting, determine the location of an acceptable mounting support. All charging
station products 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.

15
4.2 Install the charging station
1. Separate the front and back piece of the mounting bracket by pushing down on the
notch.
2. Aach the front piece of the mounting bracket to the back of the charging station
using the socket cap screws. Ensure the top of the mounting bracket is matched with
the top of the charging station.
Back Piece
Front Piece
TOP

16
The back piece of the mounting bracket has 3 holes to support aachment to various
surfaces. Use the top two holes to aach the mounting bracket to a wall stud.
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).
• Use following torque force:

3. Secure the back piece of the mounting bracket to the wall or other suitable structure
using the Robertson-head screws.
The NEMA 14-50 cable is approximately 24” (30cm) long. Mount the unit so the NEMA 14-50
cable is straight but can be plugged into the outlet without stretching. The NEMA outlet
should be located no less than 20~26” (50-60cm) from the ground or as dened by applicable,
local electrical safety codes and standards.

4. Mount the charger on the wall by securing the front piece of the mounting bracket to the
back piece of the mounting bracket.
5. Secure the charger in place by inserting either the security pin or the outdoor security
lock into the mounting bracket.
6. Plug in the power cord to the NEMA 14-50 wall outlet/receptacle. Ensure the indicator
light alternates between Blue and Magenta, indicating the charger is ready and not
connected to Wi-Fi.

5. Input wiring connection (optional hardwire connection)
1. Choose the appropriate conduit in accordance with all applicable, local, and electrical
safety codes and standards.
2. Using the appropriate tool, clamp the ring wire terminal to the copper wire. For non-
insulated terminals, use the heat shrink tube to cover the non-insulated portion of the
terminal. Choose a terminal ring with the following characteristics:
»Recommended wire strip length: 8mm (0.32in)
»Width of the terminal block opening: 10.2mm (0.41in)
3. Remove the front cover by removing the 4 screws at each corner of the charging station.
For more information on how to remove the front cover refer to Chapter 3.1 Adjust
maximum current output on page 11.
4. With the front cover placed to the side, use a Phillips screwdriver to release terminal
screws of the input cable. Loosen the strain relief ing for the 14-50 plug and remove the
plug.
5. 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). Aach the copper wire on the
corresponding terminal block. Use the following wire and torque force when connecting
to input terminal block.
