Control interface
In general, the basic control interface between the fieldbus system and the drive
consists of:
Protocol
Modbus
N2
BACnet
Note: The words "output" and "input" are used as seen from the fieldbus controller
point of view. For example an output describes data flow from the fieldbus controller
to the bypass.
Mechanical and electrical installation – Embedded Fieldbus (EFB)
Warning! Connections should be made only while the bypass is disconnected from
the power source.
Bypass terminals 26...30 are for EIA 485 communications.
• Use Belden 9842 or equivalent. Belden 9842 is a dual twisted, shielded pair cable
with a wave impedance of 120
• Use one of these twisted shielded pairs for the EIA 485 link. Use this pair to
connect all A (-) terminals together and all B (+) terminals together.
• Use both of the other wires in the other pair for the reference/common
(terminal 29).
