12 Installation
12.1 General
The standard version of the calculating machine is supplied as panel mounting set (144 X 77 mm 5.7" X
3.03"). The cutoff in this panel must be 137mm wide (5.4") and 67 mm (2.6") high. The depth is 130 mm
(5.1").The set ist fastened with the supplied mounting clamps.
The feeding of transmitter is carried out via a voltage supply output. This output delivers a voltage of about
18V, which can be set by an parameter at configuration. The maximum output current is 100mA.
The flow computer will be supplied by either 24V DC or 115/230V AC. The built-in mains transformer worries
for a complete galvanic isolation between main power and the signal input- and output circles.
If the transmitter is in larger distance installed by the flow computer, in each case shielded cables should for
the inputs and outputs, also in regard on EMC strength be used.
Make sure that the shielding may be grounded only at an end.
suppression filters:
If inductive loads are switched with the relay output, it may be necessary to provide a filtering module under
circumstances
