Anti-condensation heating (option L55)

The anti-condensation heating is used at low ambient temperatures and high levels of humidity
to prevent condensation from forming. The heating is controlled via a thermostat.
The number of anti-condensation heaters is set in accordance with the number of cabinet
panels.
The converter monitors and signals if the external supply for the anti-condensation heating
fails.

EMERGENCY STOP Category 1 (option L60)

Emergency Off, stop category1 (24 VDC) for controlled stop according to IEC60204.
In the standard version, Emergency Off stop category 0 is set for an uncontrolled stop. It also
has a function for disconnecting the drive from the power supply via the circuit-breaker. The
motor coasts down. The Emergency Off, stop category 1 function includes rapid stopping of
the drive using a deceleration ramp to be parameterized by the user. Voltage is then
disconnected from the drive as described for Emergency Off, stop category 0.
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.
