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
and C3 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.
