5.11.3 Routing Control Cables
Make sure to use the provided wire pathway when routing the control wires from the bottom of the drive system cabinet to the
control terminal.
Procedure
Tie down and route all control cables at the bottom of the enclosure.
Isolate control cables from high-power cables in the drive.
Connect the shields in a proper way to ensure optimum electrical immunity.
When the drive is connected to a thermistor, ensure that the thermistor control cable is shielded and reinforced/double
insulated. A 24 V DC supply is recommended.
Connect the control cables to the relevant options on the control card. For more detail, see the relevant fieldbus instruc-
tions. The fieldbus cable must be tied down and routed along with the other control cables inside the unit.
All control terminals are on the control shelf below the LCP.
