IMPORTANT SAFETY INSTRUCTIONS

SAVE THESE INSTRUCTIONS - These instructions contain important safety and operating

instructions for the MidNite Solar MNBE-8D2x2 and MNBE-8D2x2-Deluxe Battery Enclosures for residential and
commercial applications.

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

WORKING WITH OR IN THE VICINITY OF A LEAD ACID BATTERY, SEALED OR VENTED IS
DANGEROUS. VENTED BATTERIES GENERATE EXPLOSIVE GASES DURING NORMAL OPERATION.
FOR THIS REASON, IT IS VERY IMPORTANT THAT BEFORE SERVICING EQUIPMENT IN THE
VICINITY OF LEAD-ACID BATTERIES, YOU REVIEW AND FOLLOW THESE INSTRUCTIONS
CAREFULLY.

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.

Never attempt to charge a frozen battery. When it is necessary to remove a battery, make sure that the battery bank
disconnect breaker is in the off position and that the PV breakers, grid breakers and any other sources of power to
the inverter are in the off position. Then remove the negative terminal from the battery first.

To reduce risk of battery explosion follow these instructions and those published by the battery manufacturer as
well as the manufacturer of any additional equipment used in the vicinity of the batteries. Before installing the
battery enclosure, read all instructions and cautionary markings in or on any connected electrical equipment.

Avoid producing sparks in the vicinity of the batteries when using vented batteries. Provide ventilation to clear the
area of explosive gases. Sealed AGM and Gel batteries do not under normal conditions create explosive gases. Be
especially cautious when using metal tools. Dropping a metal tool onto batteries can short circuit them. The
resulting spark can lead to personal injury or damage to the equipment. Provide ventilation to outdoors from the
battery compartment when installing vented batteries such as golf cart T-105 batteries. The addition of a spill tray is
also a good idea.

Clean all battery terminals. Very high currents are drawn from the batteries; even a small amount of electrical
resistance can result in overheating, poor performance, premature failure or even fire.
Have plenty of fresh water and soap nearby in case battery acid contacts skin, clothing or eyes. Wear complete eye
and clothing protection. Always avoid touching eyes while working near batteries. If battery acid or battery terminal
corrosion contacts skin or clothing, wash immediately with soap and water. If acid enters the eyes, immediately
flood with cool running water for at least 15 minutes and get medical attention immediately. Baking soda
neutralizes battery acid electrolyte. Keep a supply near the batteries.

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
electrical 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.

To reduce the risk of injury, connect only deep cycle lead acid type rechargeable batteries. Other types of batteries
may leak or burst, causing personal injury or damage.

Unpacking is the same for each model except that the Deluxe model has extra components shipped within the shelf.

Before unpacking and assembly make sure there is enough space to work in comfortably. It is recommended to
unpack the painted pieces onto carpet or other soft surface to avoid scratching.

Assembling the MNBE-8D2x2 and MNBE-8D2x2-Deluxe

Assembly of the MNBE-8D2x2 and MNBE8D2x2-Deluxe is essentially identical. The differences between the two
models is that the deluxe model comes with extra components.

The MNBE-8D2x2 and Deluxe are 3R outdoor rated. In order to maximize rain-tightness, silicone sealant (Not
included) is applied to several locations on the box during assembly.

General instructions below. Refer to the assembly drawing on page 7.
