Description
3.6 Description of options
The EMERGENCY OFF button with protective collar is installed in the drive cabinet door.
Danger from auxiliary voltages that are connected
When you press the EMERGENCY STOP button, the motor is stopped either uncontrolled or
controlled depending on the selected category 0 or 1, and the drive blocks the inverter, in line
with IEC60204-1 (VDE0113).
Auxiliary voltages such as those for separately-driven fans or anti-condensation heating are
still present. Certain areas within the drive also remain under voltage, e.g. the control function
or auxiliaries. When touching these auxiliary voltages, this can result in death or serious
physical injury.
Ensure that the EMERGENCY OFF button is integrated in the safety system for the whole
machine so that all the voltages are completely disconnected. For this purpose, an NC contact
is installed at terminals =.LA–X51:1A or 1C and =.LA–X51:2A or 2C.

Braking Module (option L72)

This option uses a Braking Module with connected braking resistor to permit braking operation.
The structure of the Braking Module is similar to that for a phase of the Motor Module. The
braking resistor is not included in the scope of supply but is available as option Y73. An external
load resistor is provided as the braking resistor.
