Customer terminal block X55.1
Description
The customer terminal block (-X55.1) is mounted as standard in the cabinet for each
Booksize Cabinet Kit. It provides the function-related inputs/outputs for temperature
monitoring and for the "Safe Torque Off" and "Safe Stop 1" functions.
Note
Additional information
All other cabinet interfaces and connections a
re explained in the circuit and terminal
diagrams on the customer DVD supplied.

WARNING
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
separation.
• If safe electrical separation cannot be guaranteed (for linear motors or third-party
motors, for example), use a Sensor Module External (SME120 or SME125) or the
Terminal Module TM120.
