The protection class IP20 is achieved with fitted covers.
Make sure that the covers are always mounted for opera-

* The 6-phase connection must be done through the same mains connections and a suitable transformer (in ex-
ample one Delta and one Star winding on the secondary side), which shifts all phases to each other by 30°. Alter-
natively two transformers can be used (one with Delta winding, one with Star winding on the secondary side).
