T40FH A4429-1.0 HBM: public 43
The information in this Chapter relates to the standalone
operation of the T40FH without HBM system solutions.
The supply voltage is electrically isolated from the signal
outputs and shunt signal inputs. Connect a safety 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 appropriate sockets (see
accessories, Page 62). 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 feed
the supply voltage in parallel over two connection cables
(connectors 1 and 3). This enables you to double the per
missible length. Alternatively, install an on-site power
supply.
Important
The instant you switch on, a current of up to 4 A may
flow and this can switch off power packs with electronic
current limiters.
6.6 Supply voltage (Option 3, Code PNJ)
A pre-wired 6-wire transducer connection cable with free
ends is available as an accessory.
Extension cables should be shielded and low capaci
tance. HBM provides specific cables for this purpose, the
1-KAB0304A-10 (pre-wired) and the KAB8/00-2/2/2 (by
the meter).
The pin assignment can be found in the table in section
6.4.
For the pin assignments at the amplifier end, please refer
to the relevant amplifier documentation.
