4.4.3 Auxiliary power supply

The power supplies required for the controls (+/- 15V, 5V, ventilators) are taken from an
intermediate direct-current voltage which can be:
Either obtained via a single-phase power source coming from the mains, bled off between 2
phases upstream from the main contactor (B3 terminal block input).
- please remember that the internal wiring is as follows:
THREE-PHASE
- The auxiliary power source input must be taken between two phases (L1,L2), (L2,L3) or (L1,L3)
in the case of three-phase and between (L,N) in the case of single-phase, upstream from the
main contactor (please refer to the relevant connection diagrams: FELX 306198 for single phase
and FELX 306199 for three-phase).
- Or obtained via an independent single-phase power source, and connected to the B3 terminal
block. In this case, this power source must be isolated from the mains via a transformer
(secondary 230 +/-10% 100VA).
- Or obtained from the intermediary mains voltage, through diodes (B3 is not
connected). In this option (not recommended), the cutting-off of the mains power
source leads to the loss of the low level power sources and, in particular, the pulses
generated by the "encoder emulation" option.
