Usage Features:

Adjustable Maximum Current Output: The charger's output can be set to 16, 24, 32, or 40 Amps using DIP switches located inside the unit, allowing it to be safely used with different circuit breaker ratings (20A, 30A, 40A, or 50A respectively). The default factory setting is 40A (9.6kW).
Wi-Fi Connectivity: Enables smart charging features and compatibility with OCPP 1.6 applications. Users can connect the charger to their Wi-Fi network and then to the United Chargers OCPP Network or a third-party OCPP network for remote control and monitoring.
Plug-in Configuration: Designed for easy portability, allowing for flexible installation.
Wall Mount with Security Features: Includes a security pin to secure the charging station to the wall mount bracket. A coupler lock and key (90mm length, 7mm diameter) can also be used for added security.
EasyEvPlug™ Holster and Cable Management System: This innovative system protects the charging plug and manages the cable, offering features like flawless plug insertion even in the dark, convenient placement, space-saving design with a special angle for less wall clearance, and integrated cable management that holds up to 25 feet of cable.
Charging Operation: To charge, the user inserts the charging connector into the EV until it is fully seated and locked. Charging begins automatically. To stop charging, the connector button is pressed, and the connector is removed from the EV, then returned to the holster.
Self-Monitoring and Recovery (Auto Restart): In case of temporary error conditions (e.g., Over Current, Under Voltage, Missing Diode, Ground Fault, Over Temperature), the charging station will attempt to restart every 30 seconds. If an error persists after 4 attempts over 15 minutes, the buzzer will sound continuously, and the status indicator will turn red, indicating a permanent error.

Maintenance Features:

No Routine Maintenance Required: United Chargers products do not require routine maintenance, but periodic inspections are recommended to ensure all parts are in good working order and free from damage.
Product Care: The exterior is waterproof and dustproof (NEMA 4 Outdoor Rated). Cleaning should be done with an automotive-grade soft cleaning cloth, soap, and water. Cleaning solvents should not be used.
Handling: When moving or lifting the unit, it should always be grasped and carried by the charging station body, not by the electrical cables, to prevent damage.
Troubleshooting Faults: If a "Red Steady" or "Red Flashing" fault indicator persists, users are instructed to unplug the connector, turn off the power at the circuit breaker for 1-2 minutes, then restore power. If the fault remains, technical support should be contacted.
Wi-Fi Board Reset: If the charger loses Wi-Fi connection, there's a procedure to reset the Wi-Fi board by unplugging the charger, removing the front cover, moving the left DIP switch to the down position, plugging the charger back in for 30 seconds, unplugging it, setting the DIP switches back to original, and then plugging it in again to re-establish the Wi-Fi and OCPP network connection.
Warranty: The Grizzl-E Smart EV Residential Charging Stations come with a 3-year or 5-year manufacturer's replacement warranty, covering defects in materials and workmanship from the date of purchase. Misuse, abuse, alteration, or normal wear and tear of the cable are not covered.
