Battery Connection
Connect your UPS System to your batteries using the following procedures:
•Connect DC Wiring: Though your UPS System is a high-
efficiency device, its rated output capacity
is limited by the length and gauge of the cabling running
from the battery to the unit. Use the shortest length and largest diameter cabling (maximum 2/0 gauge) to fit your UPS System’s DC Input terminals. Shorter and heavier gauge cabling reduces DC voltage drop and allows for maximum transfer of current. Your UPS System is capable of delivering peak wattage at up to 200% of its rated continu- ous wattage output for brief periods of time. See Specifications page for details. Heavier
gauge cabling should be used when continu- ously operating heavy draw equipment under these conditions. Tighten your UPS System and battery terminals to approximately 3.5
Minimum Recommended Cable Sizing Chart.
•Connect Ground: Using a #8 AWG wire or larger directly connect the Main Ground Lug to earth ground. See the Feature Identification section to locate the Main Ground Lug on your specific UPS System model.
All installations must comply with national and local codes and ordinances.
•Connect Fuse: NEC (National Electrical Code) article 551 requires that you connect all of your UPS System’s positive DC Terminals directly to a
WARNING!
•Failure to properly ground your UPS System to earth ground may result in a lethal electrical shock hazard.
•Never attempt to operate your UPS System by connecting its DC terminals directly to output from a generator rather than a battery or battery bank.
•Observe proper polarity with all DC connections.
In a parallel connection, your UPS System’s Nominal DC Input Voltage (12V DC) must match the voltage of your battery or batteries (12V DC). In a series connection, your UPS System’s Nominal DC Input Voltage must match the number of batteries multiplied by their voltage. For example, a 12V DC UPS System would require two 6V batteries connected in series (12 = 2 × 6). See diagram below.
