Installation and Operations Manual
• The purpose of the Amperage Adjustment dial is to
set the maximum current that the EV is allowed to
draw from the charging stations.
• The dial has 10 settings.
• Settings 0-5 are for amperage adjustments.
• Settings 6-9 are for factory use only. These
settings will result in a bad switch fault if used.

The Siemens VersiCharge has a Remote Control Interface that
can also be used to wire the Remote Control Interface to pins #7
and #9, and allows charging to be controlled by an external
device. Examples include demand response switches, building
automation systems, digital sensors, etc.
• Control Switch input is a dry contact input from an external
source.
• Status Output indicates the charging status of the
VersiCharge.
• The Remote Control Interface is located inside the unit so,
to connect a VersiCharge the unit has to be opened by
taking the following steps:

1. Remove the Multi-use Connector from the bag and wire
an additional remote control interface cable to pins #7
and #9.
NOTE: The Remote Control Interface cable is not
supplied as part of the in-box equipment.
2. Open hinged cover by loosening four cover Phillips
closure screws.
3. Remove barrier by removing the two securing screws.
4. Connect to the Multi-use connector by gently pressing
the connector on to it.
5. Press the Remote Control cable through the rubberized
gland at the back of the unit without the connector
attached. This gland will self-seal.
NOTE: Do not press the cable with the connector
attached through this gland, that will cause the loss
of the NEMA 4 rating.
6. Attach the Remote Control cable connector and attach
the two cable connectors.
7. Gently tuck the cables into the back of the unit and
close the case.
NOTE: When the external contact is closed, the
alternate input will control the VersiCharge,
preventing it from entering the 'Charging' state.
NOTE: The status output is a switch that indicates
charging status. When the contacts are closed, the
unit is in charging state.
Explosion hazard. This equipment has arcing or
sparking parts that should not be exposed to
flammable vapors. This equipment should be
