Schematic overview of power connections
Rail Light luminaires are designed to accept power input from a three-phase
system. For example:
• In luminaires containing one armature, one phase can be used to feed the
armature.
• In luminaires containing two armatures, two phases can be used to feed
two armatures.
• In luminaires containing three armatures, one phase can be used to feed
each armature. Neutral and earth are common (see Figure 8).
• In luminaires containing four armatures, one phase can be used to feed
two armatures, and the two remaining phases used to feed one armature
each (see Figure 9).
In each case, conductors are continued to the next luminaire.
