Additional information on the connections

External power supply for the control unit (XPOW)
The control unit is powered from a 24 V DC, 2.9 A supply through terminal block XPOW.
Using an external supply is recommended if
• the control unit needs to be kept operational during input power breaks, for
example, because of continuous fieldbus communication
• immediate restart is needed after a power break (that is, no control unit power-up
delay is allowed).

DIIL input
By default the DIIL input is used to implement stop as a part of safety function. The
input is parametrized to stop the unit when the input signal is lost.
A jumper wire set installed at the factory connects the DIIL input to +24 V, which
enables the drive to start. If this function is used as a part of safety function
implementation, the jumper wire set must be removed.
Note: This input is NOT SIL or PL classified.

The XD2D connector
The XD2D connector provides an RS-485 connection that can be used for
• basic master/follower communication with one master drive and multiple
followers,
• fieldbus control through the embedded fieldbus interface (EFB), or
• drive-to-drive (D2D) communication implemented by application programming.
Refer to the firmware manual of the drive for the availability of these features and
related parameter settings.
Terminate the bus on the units at the ends of the drive-to-drive link. Disable bus
termination on the intermediate units.
Use shielded twisted-pair cable with a twisted pair for data and a wire or another pair
for signal ground (nominal impedance 100…165 ohm, for example Belden 9842) for
the wiring. For best immunity, ABB recommends high quality cable. Keep the cable as
short as possible. Avoid unnecessary loops and parallel runs near power cables such
as motor cables.
