3.6 Setting Address Switches
NOTICE
Switch o the power supply before changing the address
switches. The address change comes into eect at the
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.

3.7.2 Wiring Procedures
Wiring procedure for enclosure sizes A1–A3
1. Mount the eldbus connector on the eldbus
option (CAN_L, Drain, CAN_H). For top cable
entry, mount the supplied EMC bracket on top of
the frequency converter with 2 screws.
2. Prepare the eldbus 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 specications,
refer to chapter 3.7.1 Cable Specications.
3. Connect the eldbus cable wires to the terminals
according to the colour code of the wires, see
Illustration 3.6.
4. To establish mechanical xation and electrical
contact between cable screen and ground,
position the stripped cable between the spring
loaded metal clamps.
