4.2 Mounting
▸
DIL switches are installed on the side of the enclosure for setting the termination of the
RS485 interface in the safe area . If required, set it prior to installation on the mounting
rail as described in → p. 24, §4.3.5. Termination to the gas flow meter is set fixed.
▸
Mount the FLPS Multibarrier on a 35 mm mounting rail (hat rail) according to EN
60715.
4.3 Electrical Installation
4.3.1 Cable specification
Cables and terminals
4.3.2 Connection parameters
Electrical isolation
▸
All connections to the safe area are isolated from the intrinsically safe connection and
ground.
▸
All intrinsically safe connections are not isolated from ground and must be connected to
the potential equalization (PE).
