To protect the system from electrical surges, we strongly recommend connecting the system to a surge pro-
tector that meets the following specifications:
–
Surge arrestor type: 3-electrode arrestor
–
DC spark-over voltage: 230 V
–
Maximum peak current: at least 10 kA
Additionally, proper earthing is very important for the protection of the system (refer to "3.2.4 Frame Earth
Connection").
Many countries/areas have regulations requiring surge protection. Be sure to comply with all applicable
laws, regulations, and guidelines.
