Furthermore, option K82 supports a concept of simplified wiring of the Safe Torque Off and Safe Stop1 safety
functions within a group of drives. A well-planned arrangement of terminals and associated cable connections allows
a clear and optimised cable routing without cross connections. The terminal block has been designed to support
different arrangements of modules and grouping of modules. The terminal block is easily accessible near the bottom
of the cabinet.
The voltages of the check-back signal paths can be up to 250 V DC / AC. The following rated operating currents must
be observed when using check-back contacts (-X41: 5 and 6):
·
AC-15 (according to IEC 60947-5-1):
·
DC-13 (according to IEC 60947-5-1):
Minimum switching capacity: DC 5 V, 1 mA with an error rate of 1 ppm. Protection: Maximum 4 A (fuse for operation
class gL/gG at I ≥ 1 kA).

The first example shows the wiring of option K82 with SINAMICS G150 and SINAMICS S150 converter cabinet units.
The SIMATIC S7 drive control is not required to implement safety functions STO and SS1 and is included by way of
example only.
