For installations with 485 communication, the wiring connects to the charger via the same RJ- 45 port on the device by means of 4 unoccupied connections (2 twisted pairs) on the connector.

  • Page 22: Charger Wiring Schemes

    3.1. charger wiring scheme The power and signal conductors can be connected to the device after the charger body has been mounted to the wall and the cable glands have been installed. The conductors are pulled through the gland with enough slack to make the connections without strain. The charger uses lever terminal blocks for all connections except for the output PE terminal for tethered models, which requires a round cable terminal lug.
