X41 Ep Terminal / Temperature Sensor Connection - Siemens SINAMICS S120 Device Manual

Cabinet Modules
5.6 Motor Modules in chassis format
Description
The customer interface -X55 is available in the cabinet irrespective of the CU320-2 Control
Unit. Terminal blocks -X41 and -X46 are assigned by default.
With option K90/K95, terminal blocks -X122 and -X132 are also fully assigned
(→ see "Options", section "K90, Control Unit CU320-2 DP" or section "K90, Control Unit
CU320-2 PN")
Note
Interfaces -X1, -X2, -X3, and -X4 are wired within the cabinet and are not available for
customer connections!
If the customer terminal block is ever replaced, connectors -X1 and -X2 must not be
interchanged! Otherwise, the "Safe Torque Off" and "Safe Stop 1" safety functions will
malfunction.

Risk of death from electric shock in the event of voltage flashovers at the temperature
sensor
Voltage flashovers in the signal electronics can occur in motors without safe electrical
separation of the temperature sensors.
• Only use temperature sensors that fully comply with the specifications of the electrical
