3.7.4 Wiring Procedures

Wiring procedure for enclosure sizes A1–A3

Mount the fieldbus connector on the fieldbus

option (terminals 62, 63, 66, and 67). 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 is

in contact with the EMC bracket. Keep the

unshielded wire as short as possible. For cable

specifications, refer to chapter 3.7.2 Cable Specifi-

cations. For fieldbus cable requirements, see

chapter 3.7.3 Bus Segment Requirements.

Connect the fieldbus cable wires to the terminals

according to the colour code of the wires, see

Illustration 3.10.

To establish mechanical fixation and electrical

contact between cable screen and ground,

position the stripped cable between the spring

loaded metal clamps.
