It is possible to supply the device with an external voltage source. This is usually the case in
applications where it is possible to obtain the supply voltage from a separate supply unit
(e.g. enclosure).
The nominal value of the supply voltage is 24 V DC. The TPK should be supplied with a
stabilised, short-circuit protected and surge-protected voltage source.
The power source of the pressure transducer must be from an energy-limited source (10
A max./30 V max.) and be safely separated from the mains. See EN 61010-1,
paragraph 9.4.
NOTE:
If the device is connected to an external voltage supply, the above-mentioned points
must be observed and checked.
Incorrect connection may damage the device.
