Figure 44 Connection example for 4 single-phase loads, 3-phase line with neutral
Dip-Switches configuration
Dip 1 Dip 2 Dip 3
OFF OFF OFF
- FIRING MODE: ZC, BF, HSC, PA
- HB DIAGNOSTIC AVAILABLE: Partial and total load failure of each single leg
(HB Diagnostics active with P>30%)
FAST FUSE needed only for controller without option "F" See table Fuse/Fuseholders
NOTE:
Take care about the "F4/N" connection (see the picture)
The wire "F4/N" is required always (also if Load 4 is not used)
