( Stop!
The following conditions must be met to ensure trouble-free
operation:
l General measures (¶ 12.4-1)
l In-phase connection on the mains side!
l With two-phase supply
– Cable/overload protection via a second assigned mains fuse
F1*
– Ensure current and power symmetry by a second mains
choke or mains filter Z1*
