COMPLIANCE WITH EC DIRECTIVES
1. WHAT ARE EC DIRECTIVES?
The EC directives were issued to standardize the regulations of the EU countries and ensure smooth distribution of
(1)EMC directive
The EMC directive applies not to the servo units alone but to
This servo is certified by TUV,
(2)Low voltage directive
