Only certified devices (optionally available) may be connected in the hazardous area
‣Observe corresponding notes and wiring diagrams in the Ex-specific supplement to these
Operating Instructions. If you have any questions, please do not hesitate to contact your E
+H representative.
NOTICE
SELV / Class 2 device
‣The device may only be powered by a power unit with an energy-limited circuit in
accordance with IEC 61010-1: 'SELV or Class 2 circuit'.
Device destroyed if current too high
‣Do not operate the device at a voltage source without a current limiter. Instead, operate the
device only in the current loop with a transmitter.
•Panel housing:
The terminals are located on the rear of the housing.
•Field housing:
The terminals are located inside the housing. The device has two M16 cable entries. The
