5.6 Electrical connection

5.6.1 RS-485 bus

To operate the device, it must be connected via RS-485
bus with a MENNEKES ACU. Up to 16 charging points can
be connected via RS-485 bus with an ACU.
To connect several devices via a MENNEKES
ACU, the wiring must be located in line bus topo-
logy.
Two terminals for four separate wires and two shield sup-
ports are fitted for the purpose of connecting the RS-485
bus cable.

f Fix the RS-485 bus cable in place at the height of the
exposed shielding using the shield clamp.
