Where the drive controller is used in applications with disturbance<br />
variables corresponding to environment class 3, as per<br />
EN 61000-2-4 and above (hostile industrial environment).<br />
With a dc-link between multiple inverter moduls.<br />
Characteristics of environment class 3 include:<br />
Mains voltage fluctuations > + 10% UN Short-time interruptions between 10 ms and 60 s<br />
Voltage asymmetry > 3%<br />
Environment class 3 typically applies where:<br />
a major part of the load is supplied by power converters (dc choppers<br />
or soft-start equipment).<br />
welding machines are present.<br />
induction or arc furnaces are present.<br />
large motors are started frequently.<br />
loads fluctuate rapidly.<br />
