IMPORTANT SAFETY INSTRUCTIONS

SAVE THESE INSTRUCTIONS - These instructions contain important safety and operating instructions for the MidNite

Solar Prewired MNPV solar combiner boxes.

If you do not fully understand any of the concepts, terminology, or hazards outlined in these instructions, please refer
installation to a qualified dealer, electrician or installer. These instructions are not meant to be a complete explanation of a
renewable energy system.

GENERAL PRECAUTIONS

If service or repair should become necessary, contact MidNite Solar Inc. Improper servicing may result in a risk of shock, fire
or explosion. To reduce these risks, disconnect all wiring before attempting any maintenance or cleaning. Turning off the
inverter will not reduce these risks. Solar modules produce power when exposed to light. When it is not possible to
disconnect the power coming from the Photovoltaics by an external means such as a combiner, cover the modules with an
opaque material before servicing any connected equipment.

Do not work alone. Someone should be in the range of your voice or close enough to come to your aid when you work with
or near electrical equipment.

Remove rings, bracelets, necklaces, watches etc. when working with batteries, photovoltaic modules or other electric al
equipment. Power from an illuminated photovoltaic array makes a very effective arc welder with dire consequences if one of
the welded pieces is on your person.
