Environmental recommendations
a. Environment
Observe the product's storage and operating temperature ranges. Failure to do so could disrupt
operation and even damage the equipment.
This equipment is not designed for outdoor use!
Follow the precautions and instructions below to ensure your safety and that of your environment, and
to prevent damage to your equipment.
General danger - If the instructions are not followed, there is a risk of damage to equipment.
WARNING : do not install near heat or moisture.
This symbol on the product or its packaging indicates that this product must not be disposed of
with your other household waste. Instead, it is your responsibility to dispose of your waste by
taking it to a designated collection point for the recycling of electrical and electronic appliances.
Separate collection and recycling of your waste at the point of disposal will help conserve natural
resources and ensure recycling that respects the environment and human health. For more
information on your nearest recycling center, contact your local town hall, your household waste
disposal service or the store where you bought the product.
b. Radio
The modems in the ACW range are part of the radiocommunication modems using the ISM (Industrial
Scientific Medical) bands, which can be used freely (free of charge and without authorization) for
industrial, scientific and medical applications.

b. Installation
1. Open the sensor's movable
jaw by lifting the tab on the side
of the sensor.
2. Position the sensor so that the
conductor passes between the
two legs of the magnetic circuit.
3. Close the movable jaw again
until the tongue snaps into place
on its catch.

c. Identification
The product's LoRaWAN identifier is printed on the sensor and in the status bar of the ACW configurator.
It can also be read by scanning the QR-Code.
For LoRaWAN modems, the communication keys are automatically given by the network (pairing by
"Over The Air Activation", or OTAA).
Operating principle
a. Energy recovery
As this is a stand-alone product, it needs a certain amount of time to store enough energy to be able to
start up, particularly on first use when the storage element is empty.
The minimum current required to start drawing energy is 2ARMS. The graph and table below give the
charging times for different currents in the phase conductor for cold start.
10
ATIM_ACW-CTS_UG_EN_V1.2
For currents above 40ARMS, charging time does not drop below 10mn.
In normal operation, if the line current drops below 1ARMS, the energy recovery stage is deactivated.
The sensor will continue to operate on stored energy for approximately 30 minutes.
When the current in the phase is restored, the time required to restart is given by the graph below :
In continuous operation, a line current of amplitude 1.2ARMS is sufficient to supply the transducer with
the energy required by the system without using the energy stored in the storage element.
