Section 3: Installation
3.1 Building Survey
Available voltage, current and frequency:
VersiCharge EV charging stations can draw up to 30A at 240 VAC, 50/60 Hz (7.2kW of
power). The complete electrical structure of the building must be adequately sized to
handle the entire building energy load, under peak conditions, as well as the charging
station load under operation.
Checking for adequate power includes all the connections from the utility through the
entire circuit structure to the branch circuit position and connected wiring.
Utility connection and transformer capacity - check with utility service provider to ensure
enough power is available for the building and the VersiCharge under full loading.
Available breaker positions and amperage
Verify the panel has an open position for a two pole breaker.
Verify that the additional 30 A draw from the VersiCharge will not exceed the total loading
for the Main Breaker of the structure.
Breaker selection
A 2-pole 40 A dedicated branch circuit breaker is required for both cord-and-plug
installation and hard wired installations. Siemens Part numbers: Q240 (plug-in type),
B240 (bolt-on type).
The VersiCharge must be wired on a dedicated circuit, with no other loads wired on that
circuit.
3.2 Site Selection
NOTE: To ensure optimal functionality, we do not recommend installing the VersiCharge
unit in the direct sunlight.
Accessibility
When selecting a mounting site, ensure that the coupler can reach the EV before starting
installation.
The VersiCharge will mount on the surface of the wall, protruding at least 18 inches, and
a location for installation should be chosen where there is sufficient space to park an EV,
walk past the device, open nearby doors, etc., without obstruction.
If the installation location is not already wired for installation, installation of the
VersiCharge unit should be planned with an electrician and then the electrician should
bring in the electricity according to those guidelines.
