Mounting; Electrical Connections - OHIO SEMITRONICS VT-C Mode D'emploi

4. Mounting

The DVT-XXXX can be mounted on a top-hat rail.
Note "Environmental conditions" in Section
"3. Technical data" when determining the place of
installation!
Simply clip the device onto the top-hat rail (EN 50 022) (see
Fig. 1).
Fig. 1. Mounting onto a top-hat rail 35 × 15 or 35 × 7.5 mm.

5. Electrical connections

Connect the leads acc. to the instructions on nameplate.
Make sure that all cables are not live when
making the connections!
Impending danger by high input voltage
or high power supply voltage!
Also note that, ...
... the data required to carry out the prescri-
bed measurement must correspond to those
marked on the nameplate of the DVT-XXXX
( measuring input,
and power supply, see Fig. 6)!
... the resistance in the output circuit
– may not overrange the value
R max. [kΩ] ≤
ext
(I = current output end value)
AN
– with power supply via output leads (2-wire
connection, output 4 - 20 mA) dependent on
power supply H (12 - 32 V DC)

H = Power supply [V]
R max. [kΩ] =
ext
– may not underrange the value
R min. [kΩ] ≥
ext
(U = voltage output end value)
AN
... the measurement output cables should be twisted
pairs and run as far as possible away from heavy
current cables!
In all other respects, observe all local regulations when
selecting the type of electrical cable and installing them!
