3.7 ModBus Communications Setup
Using the ModBus RTU protocol.
VersiCharge chargers can act as ModBus Child devices making any real-time data available
through the ModBus RTU protocol. ModBus Parent devices connected to the charger can access (read) this data or write data to the
charger’s registers, initiating control actions.

NOTE:
Push the RS-485 wire through the Rubberized Cable Gland and then terminate the wires into the Multi-Use
connector terminal block. This gland will not self-seal if the connector is pushed through the rubberized cable
gland and the NEMA 4 rating will be lost.
1. Push the external ModBus RTU cable through the rubberized cable gland at the back of the charger (this will self-seal).
2. Attach the external ModBus cable wires to the internal (supplied) Multi-Use connector.
