Tightening torques, control cables

Control wires must be connected with a tightening
torque of 0.22-0.25 Nm.

Electrical installation, control terminals

See section entitled Earthing of screened/armoured
control cables in the Design Guide for the correct
termination of 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 (PELV) cannot be maintained. Max. cable
diameter: 4 mm. See drawing.
Switches 1-4
The dip switch is only on the control card with
Profibus DP communication.
The switch position shown is the factory setting.
Switches 1 and 2 are used as cable termination for the
RS 485 interface. If the frequency converter is located
as the first or last unit in the bus system, switches
1 and 2 must be ON. On the remaining frequency
converters, switches 1 and 2 must be OFF.
Switches 3 and 4 are not applied.

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.
