ELECTRICAL CONNECTIONS
4
Connecting cables
The connecting cables should be selected according to the applicable installation standards
(e.g. IEC 60079-14) and the maximum operating temperature.
The connecting cable between the flow sensor and the wall bracket for remote versions is part of
the supply.
• The connecting cables must be fixed and laid so they are sufficiently protected against
damage.
• Lay cables so as to ensure that there is sufficient distance between surfaces of the flow
sensor and the connecting cable.
• If the blind plugs / cable entries supplied separately on customer request, the influence of
the components on the IP protection class of the housing or the thermal data must be
validated.
Recommendation:
IP protection class: ≥ IP66/67 according to IEC 60529
Temperature range: -40...+80°C / -40...+176°F
• The outer diameter of the connecting cable must be within the sealing range of the cable
entry (7...12 mm / 0.28...0.47").
• Unused cable entries are to be closed in accordance with IEC 60079-1 and/or IEC 60079-7
and/or IEC 60079-31 (>IP66/67).
• Before connecting or loosening the equipotential bonding cable, ensure there are no
differences in potential.
Ensure that the gaskets and incised gasket ring are tight.
CAUTION!
The IP protection category of the signal converter housing is largely determined by the cable
gland used and the installation.
Connection terminals
The capacity of the connection terminals is 0.5 mm² to 2.5 mm².
The torque of the connection terminals is 0.6 Nm.
