WARNING:
READ CAREFULLY BEFORE INSTALLING FIXTURE. RETAIN THESE INSTRUCTIONS FOR FUTURE REFERENCE.
CRITICAL SAFETY INSTRUCTIONS:
•
INSTALLATION SHOULD ONLY BE CONDUCTED BY A QUALIFIED ELECTRICIAN IN ACCORDANCE WITH NEC AND ANY
RELEVANT LOCAL BUILDING CODES.
•
RISK OF FIRE OR ELECTRIC SHOCK. FIXTURE INSTALLATION REQUIRES KNOWLEDGE OF LUMINAIRES ELECTRICAL
SYSTEMS. IF NOT QUALIFIED, CONTACT A QUALIFIED ELECTRICIAN.
•
BE CERTAIN ELECTRICAL POWER IS OFF BEFORE AND DURING INSTALLATION AND MAINTENANCE.
•
MAKE SURE THE SUPPLY VOLTAGE IS THE SAME AS THE RATED LUMINAIRE FIXTURES VOLTAGE.
•
TO PREVENT WIRING DAMAGE OR ABRASION, DO NOT EXPOSE WIRING TO EDGES OF SHEET METAL OR SHARP
OBJECTS. SUITABLE FOR DAMP LOCATIONS.
SAFETY INSTRUCTIONS
1. Make sure the battery connected to the unit has enough voltage for the controller to recognize the battery type
before first installation.
2. The battery cable should be as short as possible to minimize loss.
3. The regulator is only suitable for lead acid batteries: OPEN, AGM, GEL is not suited for nickel hydride, lithium ions
or other batteries.
4. The charge regulator is only suitable for regulating solar modules.
Never connect another charging source to the charge regulator.
The purpose of this multifunctional solar charge/discharge controller is to protect the voltage overshoot and discharge.
When sunshine is absent, the light intensity decreases. The controller will recognize the starting signal after 6 minutes and
the load will start to work according to the set parameter. When there is sunshine, the light intensity rises and the
controller recognizes the close signal after 6 minutes and the load will stop working.
