5. Setup and Installation
The SEGUMA EV-ACS3202U charger is designed for straightforward setup. It requires a dedicated NEMA 14-50 outlet (208V-240V) for operation.
5.1 Outlet Compatibility
This charger is equipped with a NEMA 14-50 plug. Ensure your electrical system has a compatible NEMA 14-50 outlet. Do not use with other outlets such as NEMA 5-15, 6-20, 10-30, 14-30, or 6-50 without the proper adapter, as they are not directly compatible and can pose safety risks.
