FCC Part 15 B (class A) EMC tests
IEEE 1547.1
TM
IEEE Standard Conformance Test Procedures for Equipment Interconnecting Distributed Resources with Electric
Power Systems.
2.8. EMC requirements
These units are equipped with the necessary filtering elements to comply with EMC requirements for industrial
applications in order to prevent disturbances in other equipment outside the installation.
All of these units are connected to the grid through a low to medium voltage transformer. This transformer gives
the unit galvanic isolation that affects its good performance in terms of noise emission (see Section "6.8.1. Grid
connection transformer"). This is why:
CAUTION
Any auxiliary element must be connected to the low voltage network powering the units via a galvanic isolation
transformer (see Section "6.8.2. Auxiliary transformer").
The maximum distance between the units and the grid connection transformer must be less than 30 meters.
2.9. Protection class
These units meet NEMA 3R degree of protection against external agents, so can be installed outdoors.
They include standard protection covers for sand/dust storms for the front and rear grilles.
2.10. Pollution degree
The pollution degree for which the units have been designed is grade 3.
Suitable measures should be taken to provide dust-free air of sufficient quality in the vicinity of the inverter.
2.11. Acoustic contamination
When on, the inverter generates a buzzing sound.
Do not place it in an occupied room, or on light supports which might amplify this buzz. The mounting surface
must be firm and appropriate for the weight of the unit.
