Electrical Wiring Safety

For safe installation, the manufacturer specifies 6 AWG copper wire rated for 90°C.

The installer must follow applicable electrical codes and confirm appropriate wiring, grounding, circuit protection, and charging current settings.

Grounding Requirements for SEV1600HW

The hardwired model must be connected to a grounded permanent wiring system.

A grounding conductor must be included with the electrical circuit conductors and connected to the equipment-grounding terminal or lead.

Grounding Requirements for Plug-In Models

The SEV1600P1450 and SEV1600P650 use grounded electrical plugs.

Their plugs must connect to properly installed and grounded outlets that comply with applicable local electrical requirements.

Warning: Incorrect grounding can result in electrical shock.

Do not modify the supplied plug. If the plug does not fit the available outlet, a licensed electrician must install a compatible outlet.

Before Installation

The Schumacher Level 2 EV Wall Charger requires a suitable mounting location, dedicated electrical circuit, and compatible electrical supply.

All installation and electrical configuration work must be performed by a licensed electrician.

Tools Required for Installation

Installation Requirements

Before installation, the electrician must:

1. Confirm that the electrical supply meets the charger’s voltage requirements.
2. Identify the required dedicated circuit breaker.
3. Verify the correct wire size.
4. Select an appropriate mounting location.
5. Confirm proper grounding.
6. Check the charging cable’s reach.
7. Determine the correct DIP switch current setting.
8. Turn off power to the installation circuit.

Choosing an Installation Location

The SEV1600HW can be mounted indoors or outdoors.

The mounting location must permit safe routing of the power supply and charging cable.

Mounting Height Requirements

The connector storage location must be mounted between:

• 24 inches (600mm) above the ground.

The manual commonly places the top of the charging station approximately 50 inches above the finished floor.

Selecting the Wall Location

1. Choose a location near the intended electrical supply connection.
2. Make sure the charging cable can comfortably reach the vehicle’s charging port.
3. Allow slack in the input wiring and output charging cable.
4. Locate a suitable wall stud using a stud finder.
5. Mark the stud location with a pencil.
6. Use a level to mark the intended top position of the charger.
7. Attach the mounting template with tape, aligning its top edge with the marked line.

The location should permit the charging gun to be stored properly and the cable to be placed in its cradle after use.

Assembling the Charging Station
