VLT ® 2900 Series Control wires must be connected with a tightening tor- que of 0.22-0.25 Nm. Tightening torques, control cables NB! Please note that the cable jacket for the relay must cover the first row of control card terminals - otherwise the galvanic isolation cannot be maintained. Max. ca- ble diameter: 4 mm. See drawing. Electrical installation, controlterminals See section entitled Earthing of screened/armoured control cables in the VLT 2800 Design Guide for the correct termination of control cables. VLT Software Dialog Connection to terminals 68-70 or Sub D:
- PIN 3 GND - PIN 8 P-RS 485 - PIN 9 N-RS 485 Sub D plug An LCP 2 control unit can be connected to the Sub D plug on the control card. Ordering number: 175N0131. LCP control unit with ordering number 175Z0401 is not to be connected. 1. The terminals are not valid for DeviceNet/CANopen. See also the DeviceNet manual, MG.90.BX.YY for fur- ther details.
