Electrical connection
T10FS A0785-150 HBM: public 55
The supply voltage is electrically isolated from signal
outputs and calibration signal‐inputs. Connect a
separated extra‐low voltage of 18 V ... 30 V to pin 3 (+)
and pin 2 ( ) of connector 1 or 3. We recommend that
you use HBM cable KAB 8/00‐2/2/2 and relevant Binder
sockets, that at nominal (rated) voltage (24 V) can be up
to 50 m long and in the nominal (rated) voltage range,
20 m long (see Accessories, Page 89).
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
permissible length. Alternatively an on‐site power pack
should be installed.
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
At the instant of power‐up, a current of up to 2 A may
flow, which could switch off power packs with electronic
current limiters.
