(1) Note: Terminals L1-L2-L3 in the Control Unit are to be respectively connected to terminals L1-L2-
L3 in the Power Unit in case of a mains up to 500 Vac, whereas they have to be directly
connected to the secondary in three-phase transformer TS in case of a mains exceeding 500
Vac. In the latter case, terminals L1-L2-L3 in the Power Unit have to be left disconnected.
