Range of application of the meter:
·3 and 4-conductor networks (TN, TT and IT net-
works).
·Residential and industrial areas.
WARNING
Risk of injury due to electrical voltage!
Rated surge voltages above the permitted over-
voltage category can damage the insulation in the
device. This impairs the safety of the device. This
can result in serious injury or death.
·
Only use the device in environments which
comply with the permissible rated surge
voltage.
·
Observe the limit values specified in the user
manual and on the rating plate.
