), additional precautions must be taken to discharge overvoltages.
The information in this section relates to the stand-alone operation of the
T12CVS8 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 to 30 V to pin 3 (+)
and pin 2 ( ) of plugs 1 or 3. We recommend using HBM cable
KAB 8/00-2/2/2 and the relevant Binder sockets, that at nominal (rated) voltage
(24 V) can be up to 50 m long, and in the nominal voltage range, 20 m long
(see “Accessories”, page 93).
If the permissible cable length is exceeded, you can feed the supply voltage in
parallel over two connection cables (plugs 1 and 3). This enables you to double
the permissible length. Alternatively, install an on-site power supply.
If you feed the supply voltage through an unshielded cable, the cable must be
twisted (interference suppression). We also recommend that a ferrite element
should be located close to the connector plug on the cable, and that the stator
should be grounded.
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.

Distribution system for electrical energy with greater physical expansion (over several test
benches, for example) that may possibly also supply consumers with high nominal (rated)
currents.
