BALLAST VOLTAGE
This fixture is normally equipped with a quad tap ballast and
is factory set to 277 volts. If 120, 208 or 240 volts is desired,
relocate power tap to appropriate voltage. (This fixture is
NOT suitable for 480 volt circuits). When this fixture is
supplied with a single voltage tap, make sure the voltage
furnished to the fixture is the same as specified on the unit.
CAUTION: Make sure all unused ballast taps are capped to avoid a short circuit to the reflector when the fixture
is energized.
