3.2 Design and function
The FLPS Multibarrier is a multichannel feed and input isolator amplifier for the electrically
isolated operation of FLOWSIC600-XT gas measuring devices and the power source (intrin-
sically safe supply).
The device supplies the gas measuring device with voltage and allows the connection via
one or two serial as well as four digital interfaces, depending on the device version.
All interfaces are electrically isolated.
The serial interfaces are typically designed as RS485. Here, one can be used for connec-
tion to a volume converter and the second for connection to a higher level system or it can
be used as service interface via integrated mini USB 2.0 interface.

4.1 Safety Information
▸ Disconnect the device from all effective power sources except the intrinsically safe
power circuits to the gas flow meter for installation, maintenance and service work.
▸ Install the device outside of hazardous areas only.
▸ Provide a switch/circuit breaker near the device and mark it as disconnecting device for
this device (or the whole control cabinet).
▸ Provide an overcurrent protective device (I ≤16 A) during assembly.
▸ The enclosure of the device provides an ingress protection degree of IP20 according to
IEC/EN60529 and is suitable for indoor installation only. If required this device is to be
installed in an addional enclosure suitable for the exicting environmental conditions.
Outdoor installion requires IP54 or higher.
▸ In particular for interconnection with a device in Zone 0 the requirements in IEC/EN
60079-14 have to be observed.
▸ For safe operation connect the grounding terminal of the device with the potential
equalization (PE). All intrinsically safe circuits of the FLPS Multibarrier must be consid-
ered as grounded circuits.
▸ Two (2) connectors with a cross-section of minimum 1.5 mm² up to maximum 2.5 mm²
(stranded/ rigid ) are recommended to connect the ground terminal. Alternatively a sin-
gle stranded wire with a cross-section of 4 mm² only with a crimping cable lug may be
used.
▸ Conductors with a minimum cross-section of 0.2 mm² and a maximum cross-section
of 2.5 mm² (fine-stranded/rigid) may be connected to the connection terminals. The
tightening torque is 0.5 – 0.8 Nm. In case of stranded wires use wire end ferrules.
▸ Connect the device only to equipment, which does not carry voltage higher than 30 V AC
or 60 V DC peak. Use SELV power supplies and equipment that meets the rquirements
of IEC/EN 60950 or IEC/EN 61010-1.
▸ The safety-related technical values of the connected field devices must be conform with
the specifications of the Data Sheet and/or the EU Type Examination Certificate.
▸ Interconnection of several active operating resources in an intrinsically safe circuit may
result in different safety-related technical values. This can endanger the intrinsic safety!
The intrinsically safe RS485 interface of the FLPS Multibarrier is only permissible for
point to point connections. Connection to a FISCO system is not permitted.
▸ Modifications and alterations on the device are not permitted.
▸ Only install and operate the device in an undamaged, dry and clean state.
▸ When the device is not used according to the documentation, the designated protection
can be impaired.
WARNING: Risk of explosion
When the device is used in non-intrinsically safe power circuits, it no longer
may be used in intrinsically safe power circuits.
▸ Then, clearly mark the device as non-intrinsically safe.

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).
