VEGABAR with display module
Function
ground
1)
Ammeter for local control
Supply voltage
12 … 36 V DC
4 … 20 mA
1) If screened cable is used, the screening should be grounded in the terminal compartment and the ground
terminal outside on the housing must be grounded according to regulations. The terminals are connected to
each other in the housing.
3.2 Connection diagram
Note:
An ammeter for local control of the output current can be connected to terminals 1 and 3. This
measurement can be made during operation without interrupting current on the supply line.

module
Note the following instructions for electrical
connection:
- Connection must be made according to the
specific installation standards (e.g. in Ger-
many acc. to the VDE-regulations).
- Terminal voltage must not exceed 36 V, to
avoid damage to the electronics.
- Electrical connection must have a pre-
ventative measure against inadvertent
polarity reversal.
- The wiring between VEGABAR and the
power supply can be carried out using
standard two-wire cable.
- Screened cable is recommended if strong
electromagnetic interference is to be ex-
pected. The shielding must be grounded at
the sensor end.
- If overvoltages are expected, we recom-
mend the installation of VEGA-overvoltage
arresters.
- In the cable connection, a seal must be
used which fits the cable.
- For instrument version EExd (pressure-
tight encapsulation) screened cable must
be used for the instrument connection.
Note the installation regulations.
