Surge Protection
This product features built-in surge protection circuitry in compliance with
applicable standards.
For comprehensive protection of a luminaire installation against lightning and
electrical surges, it is essential to cover mains supply and data input lines at
the distribution board level, by using respective primary (Type 1) and secondary
(Type 2) surge arrestors in compliance with EN61643-11/IEC61643-1.
Warning
Ensure that all required surge protection measures are in place and activated
prior to luminaire installation. Also, disconnect luminaires before operating
high-power devices such as, for example, electrical arc welders.
