Engineering Information
Customer terminal block -A55
Terminal -X10 has a connector and is provided for servicing purposes. It is important to note its max. current load
rating of 250 mA. This connection is not short-circuit-proof and the wiring and cable routing must be planned
accordingly. The connectable cable cross-section is 0.14 to 1.5 mm².
The connections of the safety function Safe Torque Off (X4) are per default pre-occupied. When option K82 is
installed, the connections to its relay combination are connected at X4. When option K82 is not installed, voltage
supply links are connected so that a pulse disable is not triggered because option K82 is missing. It is of course still
possible to connect an external interface.
