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 6-50 or 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 to Support Multiple
Circuit Ratings
The GRIZZL-E ™ charging station features the ability to adjust the maximum 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.
• To obtain the fastest charging capability of 40A, a 50A Circuit Rating must be used.
• 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.
3.1 Adjust Maximum Current Output
Figure 3-1. Four screws to remove the Charging Station Cover.

3. With the front cover placed to the side, locate the DIP switch on the charging station circuit
board. The DIP switch is a 3-position switch on the main circuit board, located directly to
the left of the LED.
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.
Figure 3-2. 3-DIP Switch Position
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.

Note:
Calibration should be done before adjusting the charging station’s maximum current output
settings.
Calibration Steps:
1. 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. Adjustable
Maximum Current Output to Support Multiple Circuit Ratings on page 12.
2. Using a non-conductive object, calibrate the Grizzl-E unit by adjusting the DIP switch
settings as follows:
Calibrate the GFCI Offset
Figure 3-8
4. Calibrating the GRIZZL-E Unit (Optional)
WARNING: Electrical Power MUST remain OFF and DISCONNECTED
before setting or changing the DIP switch. Incorrect connection may
cause electric shock.
3. Close the lid, and re-secure the screws.
4. Power ON the supply unit until the front LED light turns solid red LED. The solid red LED
indicates that the calibration is finished.
5. Once calibration is complete, follow the steps from the user manual to set the maximum
current output. Refer to Chapter 3.1 Adjust Maximum Current Output on page 12.

5.2 Install the Charging Station
1. Separate the front and back piece of the mounting bracket by pushing down on the
notch.
Figure 5-1. Mounting bracket
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 back piece of 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:

6. Plug in the power cord to the NEMA 14-50 Wall Outlet/Receptacle. 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.
5.3 Install Holster
Figure 5-5. EasyEvPlug™
1. The Holster or Tesla holster can be installed at any location near the charging station.
Once the location is determined hold the flat side of the against the wall with the label
facing up.
2. Secure the holster with the Philips-head screws. Use the anchors if attaching directly into
the drywall.
The EasyEVPlug™ Holster or Tesla EasyEVPlug™ Holster is the new innovative method to
protect your plug and manage your cord. It has the following features:
• No need to aim – flawless plug even in the dark.
• Your EV holster will always be in a convenient location.
• Saves space – special angle for less wall clearance.
• Integrated cable management – holds up to 25 feet of cable.
• Safety – use simple coupler lock to prevent unauthorized use (only on J1772 holster).

6. 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 12.
4. With the front cover placed to the side, use Philips screwdriver to release terminal screws
of the or 14-50 Plug cable. Loosen the Strain Relief Fitting for the or 14-50 Plug and
Remove the Plug. Remove the Strain Relief connector.
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). Attach the copper wire on the
corresponding terminal block. Use the following wire and torque force when connecting to
input terminal block.
