Customer interface -X55

This chapter describes only those interfaces in the cabinet unit that require additional
connection work by the customer. All other interfaces are pre-wired at the factory and are not
designed for customer connections.
Note
All connections to be established on the plant side as well as the interfaces for integration
into the plant control system are described in the circuit and terminal diagrams on the
customer CD supplied.
Description
The customer interface -X55 is installed in the cabinet independently of the CU320 Control
Unit. By default, terminal block -X10 and terminals 13 to 16 of terminal block -X4 are
assigned.
With option K90/K91 (CU320 Control Unit), terminal block -X4 (terminals 1 to 12) and
terminal block -X5 are also fully assigned as described in the following tables.
NOTICE
Interfaces -X1, -X2, and -X3 are wired internally 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 mixed
up! Otherwise, the "Safe Torque Off" and "Safe Stop 1" safety functions will malfunction.
