ASSEMBLY
The device can be mounted in any position, in compliance with the expected environmental conditions.
Use the accessories supplied for xing on a DIN rail.
Attention: magnetic elds of considerable magnitude can alter the measurement: avoid proximity to permanent
magnetic elds, solenoids or ferrous masses which induce strong alterations of the magnetic eld;
possibly, if the zero error is greater than the declared error, try a different arrangement or change orientation.
WARNING: The full content of this manual must be read before any operation. The module must only be used by
qualied electricians. Specic documentation is available via QR-CODE shown on page 1.
Electrical and electronic waste disposal (applicable in the European Union and other countries with recycling).
The symbol on the product or its packaging shows the product must be surrendered to a collection centre
authorized to recycle electrical and electronic waste.
The module must be repaired and damaged parts replaced by the Manufacturer. The product is sensitive to
electrostatic discharges. Take appropriate measures during any operation.
PRELIMINARY WARNINGS
The word WARNING preceded by the symbol indicates conditions or actions that put the user's safety at risk.
The word ATTENTION preceded by the symbol indicates conditions or actions that might damage the
instrument or the connected equipment. The warranty shall become null and void in the event of improper use or
tampering with the module or devices supplied by the manufacturer as necessary for its correct operation, and if
the instructions contained in this manual are not followed.

ATTENTION
Please, install the module as shown in the gure. Pay attention to the direction
of the current ow.
To increase the current measurement sensitivity, insert the cable several times
into the central hole of the instrument, creating a series of coils. The current
measurement sensitivity is proportional to the number of turns
