5.4 Supply voltage

The transducer must be operated with a separated extra‐low voltage (supply
voltage 18  30 V
test bench at the same time. Should the device be operated on a DC voltage

network , additional precautions must be taken to discharge excess voltages.
The information in this Chapter relates to the standalone operation of the
T40FM without HBM system solutions.
The supply voltage is electrically isolated from signal outputs and shunt signal
inputs. Connect a separated extra‐low voltage of 18 V  30 V to pin 3 (+) and
pin 2 ( ) of connectors 1 or 3. We recommend that you use HBM cable KAB
8/00-2/2/2 and the appropriate sockets (see Accessories). The cable can be
up to 50 m long for voltages 24 V, otherwise it can be up to 20 m long.
If the permissible cable length is exceeded, you can supply the voltage in par-
allel over two connection cables (connectors 1 and 3). This enables you to
double the permissible length. Alternatively, install a power supply on site.
Important
The instant you switch on, a current of up to 4 A may flow and this may switch
off power packs with electronic current limiters.

example) that may possibly also supply consumers with high nominal (rated) currents.
