VersiComm.
4.1 Building Survey
Available voltage, current, and frequency:
•
The Siemens VersiComm can be powered with either 1 phase 120VAC (VC1COMMA)
or 220-240VAC (VC2COMMA), depending on the variant purchased. The rated line
range is 47-63 Hz. The input current varies from 0.15 – 0.6A. The complete electrical
structure of the building must be of adequate size to handle peak-load conditions for the
entire building.
•
Check for adequate power: checking for adequate power includes reviewing all
connections from the utility through the entire circuit structure, to the branch circuit
position and connected wiring.
•
Utility connection and transformer capacity: check with the utility service provider to
ensure enough power is available for the building and the VersiComm under peak load.
4.2 Site Selection Recomendations
VersiComm functions optimally when installed in an elevated location, that is a height greater
than that of all EVSE connecting to the box, and within a reasonable line-of-sight distance to the
chargers due to Wi-Fi and cellular antennas locations. All VersiCharge SG units located in the
hub should be directly ahead of, or at an angle, to the VersiComm. Make sure that the
VersiComm Wi-Fi antennas are located so they have the best direct line to all chargers. When
searching for a VersiComm mounting location, take note of situations where cars will be parked
in front of the VersiCharge; this can potentially obstruct communication. Underground parking
lots may require Wi-Fi repeaters or a second VersiComm for the connection to the
VersiCharge(s), and an antennas mounted outside of the parking garage may be required for
adequate cellular coverage. A professional installer will be able to provide insight, as to optimal
placement locations.
