the main earth connection for the BIOGAS 3000. If
earthing of the armor is required, this must not be taken
from the BIOGAS 3000.
The power supply for the Modbus to Profinet converter
module must not be taken from the BIOGAS 3000. Using
the supply from the BIOGAS 3000 could make the
equipment unsafe resulting in a hazard and invalidate
the ATEX/IECEx certification.
All cables should be crimped with an appropriate
insulated ferrule for the size of the cable being used. In
addition, the cable insulation must be housed
adequately within the protective sheath of the ferrule.
Terminals that are wired should be tightened to a
