The transducer must be operated with a separated extra‐low voltage (nominal

The information in this section relates to the self‐contained operation of the
T40B, 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.
