FC 300 Design Guide
Warning against Unintended Start
1. The motor can be brought to a stop by means of digital commands, bus commands, references
or a local stop, while the frequency converter is connected to mains. If personal safety consid-
erations make it necessary to ensure that no unintended start occurs, these stop functions are
not sufficient.
2. While parameters are being changed, the motor may start. Consequently, the stop key [STOP/
RESET] must always be activated; following which data can be modified.
3. A motor that has been stopped may start if faults occur in the electronics of the frequency con-
verter, or if a temporary overload or a fault in the supply mains or the motor connection ceases.
Touching the electrical parts may be fatal - even after the equipment has been disconnected
from mains.
Also make sure that other voltage inputs have been disconnected, such as external 24 V DC, load sharing
(linkage of DC intermediate circuit), as well as the motor connection for kinetic back up. Refer to FC 300
Operating Instructions (MG.33.A8.xx) for further safety guidelines.
