Grizzl-E Mini has the ability to work with either a 240V or 120V dedicated circuit.
Grizzl-E Mini will automatically detect the outlet power and will adjust settings when the input
cable is plugged into the outlet.
To use Grizzl-E Mini with 120V outlet, use a NEMA 5-15P Male to 14-50R Female, 120V 15A
Adapter.
Installation Planning and Service Wiring:
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.
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.
Prior to using Grizzl-E Mini ensure the electrical source that can support the following Input
Requirements for the Charging Station Per local Electrical Safety Code requirements:
• 240VAC or 120VAC Dedicated Circuit
• 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.

240V Outlet Settings
Maximum Current Output
The GRIZZL-E Mini charging station features the ability to adjust the maximum current output.
Requirements govern that only 80% of the circuit rated load may be utilized. The Grizzl-E Mini
can support current output of 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)
At 240V the Maximum Current Output is governed by the DIP switches on the PCB.
The DIP switch is a 3-position switch located at the top of the PCB.

General Product Care and Use Information
The exterior of the charging station is designed to be waterproof and dust proof (NEMA 4
Outdoor Rated). However, periodic cleaning may be required, depending on local conditions.
To ensure proper maintenance of the charging station, follow these guidelines:
• To avoid damaging the finish of the products, only use an automotive grade soft cleaning
cloth with soap and water to remove accumulated dirt and dust. Do not use cleaning
solvents to clean any of the product components.
• Despite the water resistance of the enclosure, submerging the unit under water is not
recommended.
• Ensure the charging connector is put back in the holster after charging to avoid damage.
• Ensure the power cable is stored on the charging station after use to avoid damage.
• If the power cable or the charging connector is damaged, turn off the charging station
supply circuit breaker, do not use the charging station, and Contact United Chargers
Customer Support for replacement parts.
• When moving or lifting the unit, always grasp and carry by the charging station body.
Never attempt to lift, move, or carry the unit by any of the electrical cables. Improper
handling may cause damage to the unit.
