3.1.1 Removing the Cord-and-Plug Assembly for Hardwiring (Only for the Plug-Supplied 40 A Units)
Plug removal is only for the plug-supplied  A units;  A units must be hardwired. See steps - below for hardwiring instructions.
NOTE: The rating of the circuit breaker that will be required is based on the ampere rating of the EVSE;  A requires a
 A breaker, and A requires a  A breaker.
1. Secure charger to mounting bracket: Using the kit-supplied, tamper-resistant screw, secure the charger cover with one screw
on the side.
2. Install holster to charger: Align the holster with guides in the charger and drill the pilot hole. Using the kit-supplied,
tamper-resistant screw, use the third screw to secure the holster to the charger (the hole at the top of the holster).
3. Standard installation (Figure 5): Drill pilot holes and use the kit-supplied lag screw (#8 x 2-1/2” drywall screw) to secure the
holster to the wall stud.
4. Alternate installation (Figure 2, Section 2.3): Drill pilot holes and use the fifth wallboard screw with anchor to screw into the wall.
2.6 Check the System
. Turn the power on; the white Power Available light should illuminate. If it does not, verify that the outlet or wire is
putting out  V or  V using the voltmeter.

NOTE: Plug removal is only necessary when hardwiring the VersiCharge.
NOTE: This enclosure has not been evaluated for rigid metallic and rigid non-metallic conduit. In order to maintain a Type
 ULE environmental rating, a hardwired installation should use liquid-tight flexible conduit only, with conduit glands
rated UL Type , X,  or P.
NOTE: Use flexible conduit only.
. The VersiCharge will need to be mounted on the bracket to hardwire the device. Access the back of the unit by shifting the
unit up and rotating it on the bracket hinges.
. Remove the high voltage door by releasing the snaps (use a flathead screwdriver if needed to assist).
Figure . Remove the plug
. Disconnect the attachment plug wires from the terminal block by loosening the screws in positions ,  and , and remove the
ferrite core (the core will be reinstalled when hardwired).
. Do not adjust the two lugs of the pre-installed wiring. These are for factory use only.
. Disconnect and remove the strain relief and entire cord-and-plug assembly.
. Route the conductors into the VersiCharge from the conductor opening with proper strain relief.
. Pull - inches of slack through the conductor opening.
. Slide the ferrite core over the black and red wires ONLY and into position per Figure  (the green wire/ground

DANGER Hazardous voltage. Will cause death or serious injury. Turn off the power before
working on this equipment.

Installation and Operations Manual VersiCharge™ AC

The VersiCharge comes set to the maximum of the model purchased. For example, a  A model will come with the amperage
adjustment switch set to , and a  A unit amperage adjustment switch will be set to . Verify the required amperage adjustment
switch setting based on the branch circuit protection (see the table below).
NOTE: The VersiCharge cannot control the power draw to the EV; it can only communicate the current capacity to the
VersiCharge to the EV.
3.2.1 Dial Settings
NOTE: The amperage adjustment dial is for use by a qualified technician/electrician only.
• When changing the amperage adjustment dial, verify that the VersiCharge is disconnected from power.
• 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  settings.
• Settings - are for amperage adjustments.
• Settings - are for factory use only. These settings will result in a bad switch fault if used.
Amperage Settings
Switch Position Amperage
0 12
1 16
2 24
3 32
4 40
5 48
NOTE: Do not set the switch above the  A unless
hardwired via the dedicated  A branch protection.
Settings:  -  amperage adjustment settings are used for
the  A charger (Note: the # position will cause a bad
switch fault for the  A charger) and  -  amperage
adjustment settings are used for the  A charger. Setting
the amperage adjustment higher than  will result in a
fault.
3.2.2 Circuit Requirements
• The circuit must be sized for the maximum ampere requirement. Do not derate breakers or conductors based on
amperage adjustment.

3.3 VersiCharge Units with a Remote Control Interface (Commercial Units)
Figure . Remote control termination point
The Siemens VersiCharge has a Remote Control Interface that allows charging to be controlled by an external device by wiring a
remote control interface to pins # and #. Examples include demand response switches, building automation systems, digital
sensors, and so on.
• 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:
Pin Label Description
Utility_ Utility lockout (dry contact input; locked
when closed)
Utility_
. Remove the multi-use connector from the bag and wire an additional Remote Control Interface cable to pins
# and #.
NOTE: The Remote Control Interface cable is not supplied as part of the in-box equipment.
. Access the back of the unit by shifting the unit up and rotating it on the bracket hinges.
WARNING! Remote Control Interface should be low-voltage, control wiring (AWG [.mm]).
Installing higher voltage on this interface can cause damage to the unit, preventing it from
functioning properly. Do not hook up / V to these connections.

. Remove the small access door by releasing snaps (use a flathead screwdriver if needed to assist).
. Connect to the multi-use connector by gently pressing the connector on to it.
. Press the Remote Control Interface 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; this will cause the loss
of the NEMA  rating.
. Attach the Remote Control Interface cable connector and attach the two cable connectors.
. Gently tuck the cables into the back of the unit and close the case.
NOTE: When the external contact is closed, no charging will occur.
NOTE: The status output is a switch that indicates charging status. When the contacts are closed, the
unit is in a charging state.
3.4 SIM Card Installation – If Not Factory-Installed (Commercial Parent Units Only)
Figure . SIM card installation
This hardware uses a micro SIM card, but with an adapter will allow nano SIM cards.
The SIM card should NOT require a PIN and must be an IoT SIM card. Locked SIM cards are not supported by VersiCharge hardware.
The following carriers are supported: for USA: AT&T and T-Mobile; for Canada: Rogers and Telus. Data plans should have a
minimum consumption of  MB per month per charger.
Explosion hazard. This equipment has arcing or sparking parts that should not be exposed to
flammable vapors. This equipment should be installed at least  inches above the floor or ground
level. Use extreme caution and follow instructions carefully.
