External intrinsically safe
zeroing contact (option), is
subject of a separate EEx - certificate.
Note :
EEx - version : In - and outputs
(connectors 15 to 27) are galvanically
isolated. Sensor connections (1 to 9) are
intrinsically safe.
HT- SENSORS (High Temperature):
Screen to ground connection MUST
BE done. An additional potential
equalising cable is required (see Manual).
NT/ ETx - Sensors:
please DO NOT connect !
Not EEx - version : In - and outputs
(connectors 15 to 27) are galvanically
isolated. Sensor connections (1 to 9) are
not intrinsically safe.
