Warning
Only a qualified person should make electrical
connections to the system.
Ensure the power is isolated.
Cable glands should meet the requirements of
Gland Selection and Cord Anchorage
Cable insulation and conductor sizes must meet the
requirements of
Cable Conductor Sizes and Insulation
If using armored cable, the armor must not be used as
the main earth connection for the BIOGAS 3000. If
earthing of the armor is required, this must not be taken
from the BIOGAS 3000.
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.
The maximum rated voltage of the relays to 24Vdc.
Exceeding this voltage will invalidate the ATEX/IECEx
certification.
Terminals that are wired should be tightened to a
minimum of 0.6N
m. Failure to tighten to this
requirement could make the equipment unsafe
resulting in a hazard and invalidate the ATEX/IECEx
certification.
