12.2 Supply the Electronic Board PWI30

The MULTIDRIVE thyristor unit, to work, requires a voltage supply for the electronic boards. This voltage
is used also to supply the internal fans.
The consumption is 20VA max, at this you must add the consumption of the internal fans (see par. 8.2).
The voltage supply for the electronic boards is configured in line with customer requirements that are
defined in the Order Code. The Order Code is written on the identification label.
Warning: Before connecting or disconnecting the unit check that power and control cables
are isolated from voltage sources.

12.3 External Feed-Back

The MULTIDRIVE thyristor unit has an input for external Feed-Back. It can be activated by the Feed-Back
select (see par. 11.6)
