When installed, terminal 4 is situated at the top front of the unit (see Fig. 7-1 to
7-3).
Table 7-9 Terminal assignment for the "safe stop" option
On units ≥ 22 kW ( 6SE7024-7TP_0,
Exception:
6SE7026-0TP_0, 6SE7027-2TP_0) terminal 1 is at the
top front when installed (see Fig. 7-1 to 7-3).
The field coil of the safety relay is connected at one end to the
grounded electronics frame. When the field coil is supplied via an
external 24 V supply, its negative pole must be connected to ground
potential. The external 24 V supply must comply with the requirements
for PELV circuits to EN 50178 (DIN VDE 0160).
In the shipped state, a jumper is inserted between terminals 3 and 4.
The jumper must be removed before the "SAFE STOP" function can be
used and an external control for selecting the function connected.
If the safety relay is supplied via the internal supply at X533:4, the
external 24 V supply must deliver at least 22 V at terminal X9:1/2 to
ensure that the relay picks up reliably (internal voltage drop).
