VersiCharge™ AC Installation and Operations Manual

The VersiCharge comes set to the maximum of the model purchased. For example, a 40 A model will come with the amperage

adjustment switch set to 4, and a 48 A unit amperage adjustment switch will be set to 5. 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 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.

Amperage Settings

Switch Position

NOTE: Do not set the switch above the 40 A unless

hardwired via the dedicated 60 A branch protection.

Settings: 0 - 4 amperage adjustment settings are used for

the 40 A charger (Note: the #5 position will cause a bad

switch fault for the 40 A charger) and 0 - 5 amperage

adjustment settings are used for the 48 A charger. Setting

the amperage adjustment higher than 5 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.
