Make sure you are wearing adequate eye protection. 9. Connect one end of the longer 1. 0 meter RED wire to the + POS connection on the inverter. Secure with supplied lock washer and nut. This connection will create a spark: Connect the other end of the longer 1. 0 meter RED wire to the end of the supplied fuse block that is closest to the inverter. Secure with supplied lock washer and nut. Safe operation of the Sima STP-3000 requires a solid, low resistance connection to the DC power source. Page 6 of 14 5. 1 Battery Cables ( if cable installation kit is not included) Safe operation of the Sima STP-3000 requires proper wires. Low resistance wiring from the battery to the Sima STP-3000 is essential to deliver high input currents at low supply voltages. Do not undermine the maximum efficiencies from your inverter and batteries with undersized copper wires. It is recommended using 2 x # l AWG or 1 x 3/0 AWG copper cable (90°C insulation rating) as the minimum size for battery connections to the Sima STP-3000. Minimize cable length to less than 10ft (3 meters) in order to maintain overall efficiency. Lower efficiency results in shorter battery run-times. Inverters may shut down below 10-volts if excessive voltage drops across the battery cables. See Table 5 for cable length and sizing. Table 5: Recommended DC Cables Sizes for Permanent Installation, for voltage drop less than 0. 5Vdc total. Based on 90°C Cable. Length of each Cable Up to . . . (6. 1m) SIMA STP-3000 Minimum Cable Size if Minimum Cable Size if Using Single Cables Using Double Cables No. 3/0 AWG Use cables rated at 90°C. For cables rated below 90°C or run in conduit, refer to your local and national electrical codes. CAUTION!National Electrical Code (NFPA 70), 1993, and on Table 1 of the Canadian Electrical Code, Part 1. Connect the supply cables to the DC terminals on the Sima STP-3000 via 5/16-inch ring terminals fixed to the cable with insulation stripped off over a length of 1/2 inch (1. 25cm) from the ends. Equivalent cable box-lug terminals (available at electrical parts suppliers) may also be used with the bare cable end inserted into the lug terminal. Secure the other cable ends to the battery terminal posts with lugs or connectors to ensure low resistance connection. Proper safe operation of the Sima STP-3000 requires solid, low resistance connection to the DC power source. Do NOT Tin the Cable Ends with Solder. Doing So Will Result in Poor Long-Term Connection! CAUTION! [. . . ] STEP 2 Estimate duration of tool operation between battery charge-discharge cycles or each appliance being driven by the Sima STP-3000. STEP 3 Calculate the total watt-hours of operations, total running time in hours, and average power consumption as exemplified below: Average Power Consumption = 3275 watt-hrs ÷ 1. 8 hours = 1819. 44 watts For Sima STP-3000 inverter, Ampere-Hour Consumed = 3275 ÷ 10 = 327. 5 ampere-hours STEP 4 Locate the battery size meeting the required operating time at the calculated power consumption level from Table 3. For the example shown, operation duration of 1. 8 hours at 1819. 44 watts requires the smallest battery size as two 400 amp-hr batteries in parallel, offering about 10 to 12 hours of operating time.
