In order to use the device safely, it is critical that individuals who handle it follow the
safety measures set out in the standards of the country where it is being used, use the
necessary personal protective equipment, and pay attention to the various warnings
indicated in this instruction manual.
The DCB-72 Vac device must be installed by authorised and qualified staff.
The power supply plug must be disconnected and measuring systems switched off before handling, al-
tering the connections or replacing the device. It is dangerous to handle the device while it is powered.
Also, it is critical to keep the cables in perfect condition in order to avoid accidents, personal injury and
damage to installations.
The device’s functionality is limited to the category of measuring voltage or specific current values.
The manufacturer of the device is not responsible for any damage resulting from failure by the user
or installer to heed the warnings and/or recommendations set out in this manual, nor for damage
resulting from the use of non-original products or accessories or those made by other manufacturers.
If an anomaly or malfunction is detected in the device, do not use it to take any measurements.
Disconnect the device from the power supply (device and measuring system power
supply) before maintaining, repairing or handling the device's connections.
Please contact the after-sales service if you suspect that there is an operational fault
in the device.
