5.1 Controller Electronics - CPU/ PSU crate
The CPU/ PSU crate is already mounted in our factory. If a removal is required, loosen the
4 screws and remove the complete crate gently. Replace the connected flat cables with
caution.
5.2 Supply voltage
The high voltage/low voltage power transformer MUST ABSOLUTELY provide a three
phase star system with available neutral (3NPE-400), and rated line voltage 380 V to 415
V between phases and 220 V to 240 V rated voltage between each phase and neutral.
See “Protections” for more details.
The supply cable must have the four current-carrying power conductors (not necessarily
the PE conductor) twisted under the same sleeve, in order to reduce the electrical noise
induced by large dimmed currents.
The neutral conductor must be of equal or larger size than the phase conductors.
See the Appendix to this manual for more details about power supply systems for dimmer
systems.
