IMPORTANT SAFETY INSTRUCTIONS
SAVE THESE INSTRUCTIONS
THIS MANUAL CONTAINS IMPORTANT INSTRUCTIONS FOR THE MIDNITE SOLAR ROSIE
E-PANEL THAT SHALL BE FOLLOWED DURING INSTALLATION AND OPERATION.
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. Before
using the Rosie and E-Panel, read all instructions and cautionary markings. The installation
instructions are for use by qualified personnel only. Do not perform any installation other than
that specified in this manual unless you are qualified to do so. Incorrect installation may result
in a risk of electric shock, fire, or other safety hazard.
Safety Symbols
The following safety symbols have been placed throughout this manual to indicate dangerous
and important safety instructions.
SAFETY PRECAUTIONS
•Live power may be present at more than one point since an inverter utilizes both DC
(batteries) and AC (utility or generator) power. To reduce risk of electric shock, ensure all
DC and AC wiring is disconnected prior to installing or performing maintenance on the
WARNING indicates a hazardous situation which, if not avoided, could
result in death or serious injury.
WARNING!
CAUTION indicates conditions or practices that could result in damage to
the unit or other equipment.
CAUTION!
INFO: Indicates information that emphasizes or supplements important
points of the main text.

inverter. Turning off the inverter will NOT reduce this risk; the inverter must be totally
disconnected from all sources.
•System grounding is the responsibility of the system installer and must comply with local and
national electrical codes and standards.
•This product is designed for indoor/compartment installation. It must not be exposed to rain,
snow, moisture, or liquids of any type.
•Listed or labeled equipment shall be installed and used in accordance with any instructions
included in the listing or labeling.
•Over-current protection of the AC & DC wiring must be provided as part of the system
installation.
•All electrical work must be performed in accordance with local and national electrical codes.
•Use Class 1 wiring methods for field wiring connections to terminals of a Class 2 circuit.
oThere are no Class 2 circuits in the Rosie E-Panel.
•Use insulated tools to reduce the chance of electrical shock or accidental short circuits.
•Torque all wiring and cable connections to the required torque values.
•Use only copper wires with a minimum temperature rating of 90°C.
•Always verify proper wiring prior to starting the inverter.
•Battery cables should be no less than #3/0 AWG.
•The Rosie E-Panel must be properly mounted.
BATTERY SAFETY
•Wear eye protection and avoid touching your eyes and face when working with batteries to
keep any fluid/corrosion on the battery from contact with eyes and skin. Have plenty of fresh
water and soap nearby and thoroughly wash in case battery acid contacts skin, clothing, or
eyes. In the event of exposure to the eyes, flood them for at least 15 minutes with running
water and seek immediate medical attention. Baking soda neutralizes lead acid battery
electrolyte and vinegar neutralizes spilled NiCad and NiFe battery electrolyte; depending on
your battery type, keep a supply on hand near the batteries.
•Read and follow the battery manufacturer’s safety precautions before installing the inverter
and batteries. Always verify proper polarity and voltage before connecting the batteries
to the inverter. Once the batteries are connected to the inverter, ensure the maintenance
and charging requirements (i.e., charge voltage and charge rate) provided by the battery
manufacturer are followed to extend the life of the batteries and to prevent damage to the
batteries while charging.
•The battery bank should be installed in a clean, dry, ventilated environment that is protected
from high and low temperatures. If installed in a vehicle/boat, the batteries must be mounted
upright (if using liquid batteries) and securely fastened. The location must be fully accessible
and protected from exposure to heat producing devices, and away from any fuel tanks.
