4. INSTALLATION
WARNING: ALTHOUGH OUR PVG UNITS ARE SHIPPED IN THE "OFF" STATE, IT IS BEST PRACTICE TO APPROACH ALL UNITS
AS IF THEY WERE IN THE "ON" STATE AND PROCEED WITH CAUTION. BEFORE WIRING, IT IS CRUCIAL TO TEST AND
CONFIRM THAT THE UNITS ARE IN THE "OFF" STATE. IF A PVG IS LEFT IN THE "ON" STATE, IT MAY RESULT IN HIGH
VOLTAGE ON THE PV STRINGS. THIS POSES A SERIOUS RISK OF ELECTRICAL SHOCK AND DAMAGE TO THE SYSTEM.
THEREFORE, ALWAYS EXERCISE CAUTION AND FOLLOW RECOMMENDED SAFETY PROCEDURES TO ENSURE THE SAFE AND
EFFICIENT INSTALLATION OF OUR PVG RAPID SHUTDOWN DEVICES.
