In this case use phase L2 as a virtual neutral. Strap
between L2 and the neutral fuse on the incoming sup-
ply, see connecting on page 9, Fig. 7.
Connect the transformer as illustrated on the right.
Connect the incoming supply 3x230 V to the primary
side and the eQ (400 V) to the secondary side. Position
the transformer so that it has proper ventilation. Maxi
