Product Wiring

Power supply

Product powered from Mains

Product must be powered through poles & of the Power & Voltage measurement terminal block.

Power supply must satisfy to the following specifications :

Min voltage : 80V (AC or DC)
Max voltage : 240V (AC or DC)

This input is typically connected to the Neutral & Phase on most installations, as shown onto the figure.

Voltage & Current measurement inputs

The product must be connected to mains through poles , , & to allow for voltage measurement.

Current transformers or Rogowski coils must also be connected to poles , , , , , to allow for current measurement.

Product wiring depends on usage and electrical network topology.

Following schematics presents possible products wiring. Please feel free to contact DotVision in case you have special needs not mentioned in the followings schematics.

3-Phase + Neutral electrical network (Delta)

Notes: Schematics present current transformers but same schematic apply when using Rogowski Coils.

Current transformers wire colors apply only to current transformers provided by DotVision.

Max voltage:

80_Vrms< V_NA < 240_Vrms

V_NB, V_NC < 600_Vrms

V_NA, V_NB & V_NC respectively refers to voltages between :

Phase A & Neutral
Phase B & Neutral
Phase C & Neutral

Rogowski coil version of the product is provided with Screw terminal blocks for rogowski coils cabling and must be wired accordingly.

Current transformer version is provided with Push-On terminal blocks. Use a screw driver to press onto the terminal blocks and insert wire. Do not try to screw these terminal blocks.

Rogowski coil version is calibrated by DotVision to ensure correct measurement. Please use intended Rogowski coils on each input. All Rogowski coils supplied by DotVision have a label indicating attached product serial number as well as target product input (1, 2 or 3). Please install exclusively product with matching Rogowski coils wired to matching inputs to obtain optimal measurement precision.
