2.8.2 Details of the SK 2x5E control connections
Control voltage 24V external! Terminal 44. If the frequency inverter does not have an optional internal mains
unit, it must be provided with an external 24V supply.
For devices in which the AS interface
is used (SK 225E and SK 235E) the control voltage supply must be
via the yellow AS interface cable
. However, in this case, the frequency inverter must not be additionally
supplied via terminal 44, in order to prevent damage to the mains unit or the AS-I bus.

For monitoring the motor
temperature by PTC.
For separate mounting of the motor
and the FI (cable length), shielded
cable must be used.
