Warning
The standstill brake that can be installed as an option is designed only for a
limited number of emergency stops.
After mounting the motor you must verify the trouble-free functioning of
the brake.
On motors with plug-in connection and built-in brake, you must install the
varistor required for wiring the brake when commissioning the motor. See
"Connecting the Holding Brake" on page 7–33.
Danger
Before the commissioning of motors equipped with a feather key at the
shaft end, the feather key must be secured against ejection.
You will find further information on the safe and trouble-free functioning of
your motor in the operating instructions that accompany each unit.
