Open loop connection to Master Bus
The control panel provides a RS485 port used to connect up to 5 expansion devices.
The RS485 bus must be connected in open loop mode, and must be balanced with a resistor inserted on the last device of the bus.
For Master Bus connection, it is recommended to use shielded multipolar twisted-pair cables with fl exible conductors.
The minimum section of the conductors must be in proportion to the extension of the bus and to the consumption of the connected
devices.
For reasons of electrical safety, the shieldings of the cables must be connected in order not to stop their path and must be
grounded inside the casing of the control panel.
The maximum length allowed for the RS485 bus (Master Bus) is 1000m. For greater distances use a fi ber optic connection by
connecting a TFSFC01 RS485- fi ber optic converter.
