To preserve the protection degree of the electric cubicle and to protect its components
from dust from the environment, it is mandatory to use a proper cable gland when
connecting the supply cable to the compressor.
Compressor control modes
The following control modes can be selected:

Emergency stop remains active. Compressor start/stop commands via Clock function are
still possible.
