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.
