SUPPLY POWER SPECIFICATIONS

Ephesus LED light fixtures are not traditional incandescent lights, they are high-tech, new generation solid-state devices.
To protect your valuable investment, the electrical power shall be clean and have stable voltage and current and undistorted
waveforms.
Power Configuration
The power transformer secondary feeding the electrical distribution system must be a three-phase, four-wire wye
configuration. If any other transformer configuration is present, notify Ephesus before proceeding with installation.

Follow proper grounding methodse: Electrical system must be grounded. If you are not sure if your power system is
grounded, DO NOT install the luminaire. Contact a licensed electrician for information on proper grounding methods
as required by the electrical code. FAILURE TO FOLLOW THIS WARNING MAY LEAD TO DEATH, SEVERE INJURY, OR
PROPERTY DAMAGE.
Circuit Voltage
Branch power circuits feeding All Field fixtures shall be 277V, 347V, or 480VAC only.
Do not attempt to connect All Field fixtures to any circuits with nominal voltage below 277V or above 480VAC.
FAILURE TO FOLLOW THIS WARNING MAY LEAD TO LUMINAIRE INTERNAL DAMAGE AND FAILURE.
The voltage on the lighting circuits must stay within 3% of nominal at 60Hz. Voltage that is consistently too high or low shall
be corrected before LED luminaires are installed.
Fusing
If individual branch circuit protection is required, Table 2 shows the minimum fuse ratings for each individually circuited
