Before setting the switches, check the BUS address range. Addresses may not be assigned twice.
Set address 1 for the first slave terminal, address 2 for the second slave terminal, and so forth.
For the connection to a master terminal, set address 2 for the first slave terminal, and so forth.

3.6 Wiring
Power supply
Power can be supplied:
via a 12 VAC - 24 VAC power transformer.
via a 12 VAC - 24 VAC low-voltage power supply unit.
via an IF-79 I/O BUS panel (max. 100 m).
Connecting the BUS cable
The IF-812/IF-815 terminal is connected to BUS1, BUS2 or BUS3 of a controller.
Connecting the I/O controller board
The I/O controller board is used for controlling electric actuators. If access control is not required, the I/O
controller board can be omitted. In that case, connection takes place directly on the terminal board using a
cable of up to 100 m length.
The IF-812/IF-815 terminal requires functional grounding in order to comply with the
EMC threshold values. The line shield is connected to terminal 8 (PE) on the terminal board as well as to
terminal 4 or 10 on the I/O controller board.
