Switching With The Control Supply Voltage - Siemens SIRIUS 3RW52 Manual

A.2.3

Switching with the control supply voltage

Requirements
● Owing to the intrinsic protection, an interval of at least 5 minutes must be allowed to
elapse before the device is restarted if the device is switched on and off in normal
operation by means of the control supply voltage.
Automatic restart.
Can cause death or serious injury.
If a starting command is pending, a restart will be triggered automatically after the reset.
This particularly applies if the motor protection has tripped. Dangerous states of the system
can result.
Reset the start command (e.g. via the PLC or switch) before performing a reset.
To do this, for example, link the group error output (terminals 95 and 96) into the control.
