3.9.15

Cabinet lighting in the control section (option L50)

The cabinet lighting is automatically switched on using an integrated motion detector. If the light
is switched on by the motion detector, it stays on for three minutes.
3.9.16

Uninterruptible power supply (option L53)

The uninterruptible power supply (UPS) ensures that when a power failure occurs, the
converter provides a controlled output current to trip the safety elements. The line is restored
after the short circuit has been removed. The auxiliary supply is not available when a short-
circuit occurs in the line. All auxiliary equipment, which does not permit a brief interruption, must
be appropriately buffered. This is used to provide the minimum supply for all open-and closed-
control components of the converter.
The uninterruptible power supply is designed for a buffer time of up to five minutes.
NOTICE
Incorrect parameterization
The converter can malfunction if you change the parameters of the UPS.
Do not change the parameters.
Uninterruptible power supply messages
The uninterruptible power supply signals the following states to the higher-level control system:
UPS state
Not ready for operation
Battery "low"
Battery mode
Note
If the uninterruptible power supply signals that a functioning battery status (battery "low") is not
guaranteed, then the internal battery should be replaced.

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.
