6.5.1. Control Wires

Control cable routing
Tie down all control wires to the designated control cable routing as
shown in the picture. Remember to connect the shields in a proper way
to ensure optimum electrical immunity.
Fieldbus connection
Connections are made to the relevant options at the control card. For
details see the relevant fieldbus instruction. The cable must be placed to
the left inside the frequency converter and tied down together with other
control wires.
In the IP 00 (Chassis) and IP 21 (NEMA 1) units it is also possible to
connect the fieldbus from the top of the unit as shown on the picture
below. On the IP 21 (NEMA 1) unit a cover plate must be removed.
