ENGLISH
Installation
1) Mains supply 115 to 230 V AC from building installation Class II. A switch or circuit-breaker
(max. 15 A) shall be included in the building installation. It must be in close proximity to the
equipment and within easy reach of the OPERATOR, and it shall be marked as the
disconnecting device for the equipment.
2)
The mains protective earth wire must be connected to the PE terminal, if the earth
wire is not connected, personnel can be exposed to 115V/230V.
Required cable min. AGW16 or 1.5 Cu wire.
For field wiring installation
National Installation Code
shall be met of the country, where the
flowmeters are installed.
Main voltage terminals must be out of reach for OPERATOR to avoid any hazards!
Intrinsically safe terminals!
It is an absolute requirement that the wires/terminals of the intrinsically safe circuits
cannot
get
into contact with the wires of the other cables. The distance between cables/wires therefore must
be at least 50 mm or otherwise protected.
It is recommended to fasten the cables/wires in a way that they, even in case of an error,
cannot
get into contact with each other. Make the wire ends as short as possible.
Digital output
If the internal resistance of the loads exceeds 10K
Ω
, it is recommended to connect an external
1-10 K
Ω
load resistor in parallel to the load.
3.
Electrical connection
When reassembling the unit, make sure that the 2 screws are properly tightened in order to ensure
a correct assembly and a proper ground connection.
Cover/insulate the power supply terminals with the plastic cover (to secure sufficient insulation).
