PRECAUTIONS
This sheet contains important precautions to prevent
damage to unit or merchandise.
Please read carefully!
See previous page for specifics on OVERVIEW,
TYPE, COMPLIANCE and WARNINGS.
CAUTION! LAMP REPLACEMENT GUIDELINES
LED lamps reflect specific size, shape and overall design.
CAUTION
Any replacements must meet factory specifications.
Fluorescent lamps have been treated to resist breakage and
must be replaced with similarly treated lamps.
CAUTION! GFCI BREAKER USE REQUIREMENT
If N.E.C. (National Electric Code) or your local code
requires GFCI (Ground Fault Circuit Interrupter) protection,
you MUST use a GFCI breaker in lieu of a GFCI receptacle.
CAUTION! POWER CORD AND PLUG MAINTENANCE
Risk of electric shock. If cord or plug becomes damaged,
replace only with cord and plug of same type.
WIRING DIAGRAM
Each case has its own wiring diagram folded and in its
own packet.
Wiring diagram placement may vary; it may be placed
near ballast box, field wiring box, raceway cover, or
other related location.
