disturbance and even damage to the equipment. ACW products in IP65 weatherproof enclosures may be placed
outdoors but should never be immersed.
Follow the precautions and instructions listed below to ensure your safety and that of your environment and to
prevent damage to your equipment.
General Danger - If instructions are not followed, there is a risk of damage to equipment.

Housing
a. Fastening
The ACW-WL modem is mounted on a flat wall using the 4 mounting holes available at
each end of the box. For best results, it is recommended to install the box at a distance
from any metal object, e.g. avoid mounting it on a metal pole. As the antenna is integrated
in the box, it must be mounted vertically in the right direction on a vertical support, or
fixed to a wall. The cable and/or the electrodes (2 screws) must always be downwards.
b. Identification
The product identifier is visible on the external label on the back of the product, inside on the
electronic board and in the status bar of the configuration software.
For LoRaWAN modems the communication keys are automatically given by the network (pairing by "Over The Air
Activation", or OTAA).
Each product of ATIM's ACW range has a QR Code label visible either on the side or on the front of the product. This
QR code can be easily read with any 2D barcode reading application on smartphone.
The reading of this code indicates the following information:
ATIM|ACW/LW8-WL-O|C.0|190114|1|3.0|5.11|70B3D59BA0008C0A

Available versions
a. Cables
ATIM offers three cable versions to complement the ACW/WL:
The CAB-WL is sold by the meter and is coupled to the ACW/WL. It allows the detection of
water leakage.
The CAB-WLL is sold by the meter and is coupled to the ACW/WL. It allows the detection and
the localization of water leak.
The CAB-WLL-OIL is sold by the meter and is coupled to the ACW/WL. It allows the detection
and location of oil or gasoline.
b. Connections and accessories
The CAB-WLL-LEAD is included by default with the ACW/WL. It connects the ACW/WL with the CAB-
WLL or CAB-WLL-OIL cable.
The CAB-WL-TERM, end of line connector, is not included by default with the ACW/WL. It
connects to the end of the CAB-WLL or CAB-WLL-OIL cable, thus closing the circuit.
The CAB-WL-CLIPS is an accessory for the ACW/WL to facilitate and simplify the fixing of the
sensing and/or locating cable.
- Dimension : 37 x 21 x 8 mm
- Fixing : to be glued or screwed (2 holes, ø4mm, distance between centres 22mm)
- Material : Flexible plastic + 2 stickers
