Figure 45: Mains circuit for safety-related disconnection of a single drive
With the PKE-SWD-32, safety switch-off of an individual drive can be imple-
mented through auxiliary contact "Enable" (terminal X3-X4). Through inclusion
of the enable path of a safety relay or the interlocked opposing N/C contact
of an emergency switching off switch, the contactor's control voltage is
interrupted in an emergency.
With this circuitry, controls can be assembled up to safety category 1 to EN
954-1
The safety relay must comply with Category 1 or higher (e.g. ESR5-NO-41-
24VAC-DC) in this example.
