4. Setup

Follow these steps to set up your SEGUMA EV Charger:

4.1 Connecting to Power Outlets

1. For Level 2 Charging (240V): Simply insert the NEMA 14-30 plug into a standard 4-prong electric dryer outlet, a dedicated NEMA 14-30 outlet, or a 24A splitter switch.
2. For Level 1 Charging (110-120V): Attach the NEMA 5-15 adapter to the NEMA 14-30 plug, then insert the NEMA 5-15 adapter into a standard household NEMA 5-15 or 5-20 outlet.
