For your safety

 

T

he transmitter must be mounted with the sensor module downwards

 

 

To maintain IP protection, the transmitter must be mounted with the sensor module downwards 

Beware of static electricity

 

 

Electronic components are sensitive to static electricity. Do not touch them directly - they may get damaged. 

The device is intended to be installed by a trained person

 

 

The product is designed only for installation by a certified technician. The manufacturer is not liable for damages resulting 

from incorrect or improper handling. 

In case of malfunction, immediately unplug from the power supply

 

 

If you notice an unusual smell or smoke emitting from the product, unplug it from the power supply, battery backup and all 

other attachments. Continued operation could result in injury or property damage. 

The transmitter is intended for use exclusively in a non

-

explosive environment

 

 

Transmitters DEGA NBx-yL II (ZONE 2) and NBx-yL III (ZONE 1) are designed for use in potentially explosive environment. 

 

Do not disassemble the product and ensure against the contact of its internal components

 

with water

 

 

Contact of internal components of the product with water may cause an electric shock. In case of any malfunction entrust the 

servicing of the product exclusively to a certified service centre. Contact with water can create a short circuit in the product 

and consequent damage to property or personal injury.
