VL6C+ ™ SPOT LUMINAIRE USER MANUAL 23
There are five connections for a wye source and four connections for a delta source. Cables are often color coded to
represent corresponding connections.
* Not applicable in Europe.
Input Voltage
When the system is configured for delta operation, the input voltage to the luminaires equals the phase-to-phase
voltage of the power source. When the system is configured for wye operation, the input voltage to the luminaires
equals the phase-to-neutral voltage of the power source. Single-phase power can be used to operate the system by
configuring the equipment for wye operation and connecting all three phase inputs to the same single-phase source.
APS6 modules usually operate under three-phase power, but can also be operated under 180-240 VAC, single phase
mains with L1, L2, and L3 tied together at the SixPack chassis.
Typical wye services in the United States produce voltages ranging from 175 to 225 VAC phase-to-phase and 90 to
130 VAC phase-to-neutral. The SixPack Chassis and the ACS rack should be placed in delta mode so that the racks
produce 175 to 225 VAC to the system. AC for the system is produced across the phases.
In Europe, wye services produce voltages ranging from 310 to 415 VAC phase-to-phase and 180 to 240 VAC phase-
to-neutral. Since the system can not operate in voltages above 260 VAC, the SixPack Chassis and ACS rack must be
placed in wye mode, thus activating the neutral and placing the system into the standard 180 to 240 VAC operating
range.
