Disposal of electrical & electronic equipment (applicable throughout the EU and other countries
wit separate collection programs). This symbol, found on your product or on
its packaging, indicates that this product should not be treated as household waste when you
wish to dispose of it.Instead,it should be handed over to an applicable collection
point for the recycling of electrical and electronic equipment. By ensuring this product is
disposed of correctly, you will help prevent potential negative consequences to the
environment and human health, which could otherwise be caused by inappropriate disposal of
it. The recycling of materials will help to conserve natural resources. For more
detailed information about the recycling of this product, please contact your local city office,
waste disposal service or the retail store where you purchased this product.
Multi-turn primary winding to improve sensibility
You can increase the sensibility of the device simply passing several times in the hole
with the measuring current, realizing turns with multiplicative effect:
For example, passing 5 times in the hole, as to see 4 turns, choosing a 50 A range,
you get an equivalent sensibility of 10 A full-scale. When you make this, let dispose the
turns with symmetry in order to preserve accuracy: use diametric contraposition with 2
turns, cross disposition with 4 turns, with 6 turns as like as 4 + 2, and so on.
Mounting
The device can be located in any position and place, in accordance with the operating
conditions above stated. Use the included holder bracket when fixing to a DIN rail.
High-strength magnetic fields may change the measured output value:WARNING:
Let avoid closeness to permanent magnets, electromagnets or iron bulks that cause
such a modification of the surrounding magnetic field; try a different arrangement or
orientation if zero error was greater than expected.
Supplied accessory for DIN rail mounting.
