2.1.1 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
neut
ral. 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 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.
2.1.2 Supply busbar
The three phase connection points are labeled L1 (phase No. 1, phase R), L2 (phase No.
2, phase S) and L3 (phase No. 3, phase T).
The Neutral is labeled N and the colour code for the Neutral is blue, as per IEC
Recommendation 446.
The Phase and Neutral connection bars have 4 holes of Ø 13 mm, with 22 mm distance
between centers. Connections are suitable for size M 12 bolts and nuts, for connection of
up to four supply conductors. The conductors must be fitted with cable lugs.
