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.
2. Installation Planning and Service Wiring:
• Prior to mounting, locate an available electrical source that can support the following
Input Requirements for the Charging Station Per local Electrical Safety Code requirements:
»40A Maximum Output Setting (Default Factory Setting): a DEDICATED CIRCUIT rated
for 50A; 208-240 VAC, 50-60 Hz, Single Phase must be used.
»32A Maximum Output Setting (Optional Setting): a DEDICATED CIRCUIT rated for 40A;
208-240 VAC, 50-60 Hz, Single Phase must be used.
»24A Maximum Output Setting (Optional Setting): a DEDICATED CIRCUIT rated for 30A;
208-240 VAC, 50-60 Hz, Single Phase must be used.
»16A Maximum Output Setting (Optional Setting): 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 Charging Unit has a built in GFCI protection; do not provide any additional GFCI
protection upstream of the charging unit.
• The Charging Stations can connect a Standard NEMA 14-50 Receptacle, or the unit can be
hardwired
2.2 Grounding Instructions
The charging station must be implemented 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 fire, 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 your circuit meets these requirements consult a
licensed electrician.
2.1 Electrical Source Requirements

3. Adjustable Maximum Current Output
The GRIZZL-E Smart charging station 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 Charging Station Default Factory Maximum Current Output Setting 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 Setting:
1. Place the Charging Station on a flat surface with the front cover facing up.
2. Remove the front cover by removing the 4 screws at each corner of the charging station.
Use a M4 Allen Key to remove the screws.
3.1 Adjust Maximum Current Output

3. 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 left of the LED.
UP DOWN
WARNING: Do not touch live electrical parts. Disconnect the power
supply to the charging station and verify no power is present before
adjusting the DIP Switches. A non-conductive object MUST be used to
adjust the DIP switch settings. 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 attached to the front cover. When the
front cover is removed, place it on a flat surface facing down 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. Attach 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.

The back piece of the mounting bracket has 3 holes to support attachment to various
surfaces. Use the top two holes to attach the mounting bracket to a wall stud.
Mounting Screw Recommendations:
• For finished 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.
Mount the unit between 24 inches (0.6 m) and 48 inches (1.2 m) from the ground. The NEMA
outlet should be located no less than 20~26” from the ground or as defined 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 or NEMA 6-50 Wall Outlet/Receptacle. Ensure
the indicator light alternates between Blue and Purple, indicating the charger is ready and
disconnected.

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 wire terminal to the copper wire. For non-insulated
terminals, use heat shrink tube to cover the non-insulated portion of the terminal.
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 Philips screwdriver to release terminal screws
of the 6-50 or 14-50 Plug cable. Loosen the Strain Relief Fitting for plug and remove the
plug.
5. Remove the Strain Relief connector.
6. 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 copper wire on the
corresponding terminal block. Use the following wire and torque force when connecting to
input terminal block.
