Battery Connection
Standard
1.Connect your APS’s positive DC Terminal directly to a fuse.
UL recommends that you install a recognized UL component fuse block and fuse within 18 inches of the battery. The fuse’s rating must equal or exceed the Minimum DC Fuse Rating listed in your APS model’s specifications on pages 16 or 17.
2.Choose a battery configuration appropriate to your batteries.
•Single Battery Connection: Refer to Diagram 4, page 37. When using a single battery, its voltage must be equal to the voltage of your APS's Inverter Nominal Input Voltage (see specs).
•Parallel Battery Connection: Refer to Diagram 5, page 37. When using multiple batteries in parallel, each battery's voltage must be equal to the voltage of your APS’s Inverter Nominal Input Voltage (see specs).
•Series Battery Connection: Refer to Diagram 6, page 37. When using multiple batteries in series, all batteries must be equal in voltage and amp hour capacity, and the sum of their voltages must be equal to the voltage of your APS's Inverter Nominal Input Voltage (see specs).
3.Use 2/0 gauge wire ONLY to make battery connections. Tighten terminals to a torque of 4
Battery connection cable lengths should be short as possible, and must not exceed the Maximum Cable Length listed under Specifications, page 16 or 17. Shorter and heavier gauge cabling limits DC voltage drop and allows for maximum transfer of current.* You must tighten your battery terminals to approximately 4
*APS models are capable of delivering a much higher wattage output for brief periods of time. Wiring should be configured to handle this brief
DC Vehicular
APS systems may be permanently mounted in a car, truck or boat and connected to draw power from the vehicle's battery. Note: An APS can ONLY be connected to vehicle batteries with voltage that matches the APS’s Nominal DC
Note: The main ground stud on the rear panel must be connected to the vehicle chassis. A
Caution: Never operate your APS from an alternator without a battery connected as shown in Diagrams 7 or 8, p. 38.
DC Ground Connection
APS systems must be connected to a grounded, permanent wiring system. For most installations, the negative battery conductor must be bonded to the grounding system at one (and only one) point in the system. All installations must comply with national and local codes and ordinances.
