IMPORTANT SAFETY INSTRUCTIONS
SAVE THESE INSTRUCTIONS !!
This manual contains important safety and operating instructions as prescribed by UL specifications
for inverters used in residential applications. This manual covers all DR series inverter/charger models.
The entire DR Series of inverters is ETL listed to the UL standard 1741 (Draft), Power conditioning
units for use in residential photovoltaic power systems. The DR series is also ETL listed to Canadian
standard CSA - C 22.2 No. 107.1 - M1, Commercial and Industrial Power Supplies.
General Precautions
1. Before using the inverter/charger, read all instructions and cautionary markings on (1) the
inverter/charger, (2) the batteries and (3) all appropriate sections of this instruction manual.
2. CAUTION - To reduce risk of injury, charge only deep-cycle lead acid, lead antimony, lead
calcium, gel cell, absorbed mat, or NiCad/NiFe type rechargeable batteries. Other types of
batteries may burst, causing personal injury and damage.
3. Do not expose inverter/charger to rain, snow or liquids of any type. The inverter is designed
for indoor mounting only. Protect the inverter from splashing if used in vehicle applications.
4. Do not disassemble the inverter/charger; take it to a qualified service center when service or
repair is required. Incorrect re-assembly may result in a risk of electric shock or fire.
5. To reduce risk of electric shock, disconnect all wiring before attempting any maintenance or
cleaning. Turning off the inverter will not reduce this risk. Solar modules produce power when
exposed to light - cover them with opaque material before servicing any connected
equipment.
6. WARNING - WORKING IN VICINITY OF A LEAD ACID BATTERY IS DANGEROUS.
BATTERIES GENERATE EXPLOSIVE GASES DURING NORMAL OPERATION. Provide
ventilation to outdoors from the battery compartment. The battery enclosure should be
designed to prevent accumulation and concentration of hydrogen gas in “pockets” at the top
of the compartment. Vent the battery compartment from the highest point. A sloped lid can
also be used to direct the flow to the vent opening location.
7. NEVER charge a frozen battery.
8. No terminals or lugs are required for hook-up of the AC wiring. AC wiring must be no less than
10 AWG (5.3 mm
2
) gauge copper wire and rated for 75
°
C or higher. Battery cables must be
rated for 75
°
C or higher and should be no less than 2/0 AWG (67.4 mm
2
) gauge. Crimped
and sealed copper ring terminal lugs with a 5/16 hole should be used to connect the battery
cables to the DC terminals of the inverter/charger. Soldered cable lugs are also acceptable.
See section on battery cable sizing for correct battery cable size and length for your
application.
9. Torque all AC wiring connections to 15-20 inch-pounds. Torque all DC cable connections to
10-12 foot- pounds. Be extra cautious when working with metal tools on, or around batteries.
The potential exists to drop a tool and short-circuit the batteries or other electrical parts
resulting in sparks that could cause an explosion.
