Instructions for mounting and wiring VS sensors

Introduction
These instructions are a non-exhaustive synthesis of the main recommendations for mounting VS voltage sensors. Each application configuration is
different, do not hesitate to contact us for advice adapted to your particular case.
Please note that incorrect or non-judicious use of sensors may lead to deterioration in the performance or operation of the sensor.
Please refer to the mounting instructions ref. 1SBC147000M1702 (VS050 to VS1500) and ref. 1SBC146012M1701 (VS2000 to VS4200) for further
information.

1 - Wiring diagram
– Direction of the current: A positive primary differential voltage (U P = U HT+ - U HT- > 0) results in a positive secondary output current Is from terminal M.
– Supply voltage: bipolar voltage -V A …0 V …+V A
VS sensors can also operate with a unipolar supply voltage (-V A …0 V ou 0 V … +V A) under certain conditions.

Please contact your distributor for further details for this application.

1.1 - VS voltage sensors with screen
The best EMC performance is obtained by connecting the screen terminal "E" to earth by a copper braid strap as short as possible.
If the electromagnetic interference is weak the screen terminal "E" can be connected to the sensor negative secondary terminal (marked "-").
