VG - Vandal Guard - Position polycarbonate vandal guard

over prismatic glass
lens. Each side of the
vandal guard should
have an attachment
screw that matches
up with a mounting
hole predrilled in the
fixture front housing.
Thread each attach­ment screw into the
appropriate mounting
hole and tighten
securely.

WG - Wire Guard ­Position wire guard
over prismatic glass
lens. Each side of the
wire guard should
have an attachment
screw that matches up
with a mounting hole
predrilled in the fixture
front housing. Thread
each attachment
screw into the appro­priate mounting hole

TB - Tapped Ballast - The tapped ballast will be wired for 277 volt at the factory. To wire a fixture that contains a tapped ballast,
first determine correct line voltage. Then select the proper fixture ballast voltage lead, remove crimped cap and connect to supply
voltage lead. The fixture lead marked COM should then be connected to the neutral supply lead on all multi-voltage fixtures; be sure
to cap off all unused fixture leads individually.
Lamp Installation - Prior to installing the lamp in the fixture, check to be sure the lamp is of proper type and wattage. Screw the lamp
securely into the socket, back the lamp out one to two turns, then screw the lamp back in, making sure it is secure. This properly
seats the lamp in the socket.
Troubleshooting - If this fixture fails to operate properly, check to make sure: • The correct lamp is properly installed •The fixture
is wired correctly •The lamp is not faulty • The fixture is grounded correctly •The line voltage at the fixture is correct.
