switches. The address change comes into effect at the
3 3
next power-up.
The address switches enable setting of baudrate and node
ID:
•
Switches 8 and 7 arefor setting the baudrate for
either: 125, 250, or 500 Kbps.
•
Switches 6–1 are for setting the node address in
the range 1–62.

Mount the fieldbus connector on the fieldbus
option (CAN_L, Drain, CAN_H). For top cable
entry, mount the supplied EMC bracket on top of
the frequency converter with 2 screws.
Prepare the fieldbus cable by stripping a section
of the cable insulation, so that the cable screen
contacts the EMC bracket. Keep the unshielded
wire as short as possible. For cable specifications,
refer to chapter 3.7.1 Cable Specifications.
Connect the fieldbus cable wires to the terminals
according to the colour code of the wires, see
Illustration 3.6.
To establish mechanical fixation and electrical
contact between cable screen and ground,
position the stripped cable between the spring
loaded metal clamps.
