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
