Synchronisation of
Multiple Choppers
The FIBER position is used if two (or more) choppers are connected to
the same intermediate circuit and must be synchronised. One chopper
– the first in the chain – acts as the master for the other choppers. The
voltage selection jumper of the master is set to the appropriate voltage,
while the slaves are set to FIBER.

WARNING! Do not touch the printed circuits. They are extremely
sensitive to electrostatic discharge.
