1.6.2 Operation Environment
According to valid standard IEC 60 721-2-1, there are delivered these versions of electric
actuators:
1) Version „temperate“ for type climate temperate
2) Version „tropical“ for type climate tropical and dry
3) Version „marine“ for type climate marine.
In accordance with IEC 60 364-1, IEC 60 364-5-51 and IEC 60 364-5-55 within valid edition the EA
have to resist external effects and operate reliably:
