* Please read the manual carefully prior to installing the meter.
* The meter should be installed and operated by qualified
personnel familiar with the construction, operation and any
hazards involved.
* Do not install the meter if it is damaged or incomplete.
* The user is responsible for proper grounding, selection,
installation and functionality of any other devices connected to
the meter, including security devices such as overcurrent
protection breakers, differential switches and surge protectors.
* Before connecting the power supply make sure that all cables
are connected properly.
* Always follow the operational conditions of the meter (voltage,
humidity, temperature).
* In order to avoid electric shock or damage to the meter,
disconnect the power before each change in connection
configuration.
* Do not modify the device on your own, as this may cause damage
or improper operation of the meter and consequently expose
the users to risk. In these cases the manufacturer is not liable for
ensuing events and reserves the right to refuse the warranty
claims on the counter.
