Warning Against Unintended Start - GE AF-650 GP Operating Instructions Manual

1.1.4 Warning against Unintended Start

1
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 considerations 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 [OFF] key must always be activated.
3. A motor that has been stopped may start if faults occur in the electronics of the frequency converter, 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.
Please take note of discharge times and further safety guidelines from the section: "Safety and conformity", in the respective Design Guide (MG.33.Ax.yy).
