The document outlines the EMC directive (2014/30/EU) relevant to fixed installations, emphasizing essential requirements for equipment regarding electromagnetic emissions and immunity. It details standards for testing emissions and immunity, including various test site procedures and harmonized standards applicable to large apparatus. Additionally, it specifies in situ testing procedures and critical tests required for compliance.

EQUIPMENT
• Fixed installation
• Apparatus
ESSENTIAL REQUIREMENTS FOR EQUIPMENT
• the electromagnetic disturbance generated does not exceed the level
• it has a level of immunity to the electromagnetic disturbance
• Just for fixed installation: a fixed installation shall be installed applying
good engineering practices and respecting the information on the
intended use of its components (TCF)

Radiated Emission:
• Measurement  30 m from the outer face of building where EUT is situated
• At least measure at four orthogonal directions
• Ambient noise 6 dB from the limit at least
• Electric field from 30 to 1000 MHz
• Magnetic field from 0.15 to 30 MHz (only if rated power exceed 20 kVA)
Conducted Emission:
• Not required for the equipment itself
• To be done on location where the equipment is installed
