4 Wiring and Connections
This chapter provides notes on cable sizing and cabling details with respect to the Argus INEX 1000/1500 Inverter
System.
4.1 Safety Precautions
WARNING
Ensure all power sources are OFF during wiring. Disconnect battery cables from battery.
Before working with any battery or power system/distribution center, follow these precautions:
• Remove all metallic jewelry; e.g., watches, rings, metal rimmed glasses, necklaces.
• Wear safety glasses with side shields (and prescription lenses if necessary) at all times during installation.
The installer should follow all applicable local rules and regulations for electrical and battery installations; e.g.,
CSA, UL, CEC, NEC, OSHA, and local fire codes.
Use OSHA approved insulated hand tools.
4.2 Tools Required
Various tools are essential for product installation. Use this list as a guide:
• Slot head screwdrivers (blade sizes: 1/4”, 1/8”, 1/16”)
• Philips head screwdriver, #2 (tip size 3/16”)
• Digital voltmeter equipped with test leads
• Adjustable 48Vdc load (optional)
• Cutters and wire strippers
• Crimping tool (optional for large gauge wire)
• Anti-static wrist strap.
4.3 Wire Selection
The INEX inverter modules are designed to operate in parallel for higher output current. Two modules are
automatically connected in parallel in each shelf. Two or more inverter shelves can be further connected in
parallel for additional output power; this is done by connecting inputs (BAT-, BAT+) in parallel, and outputs (Line,
Neutral, Ground) in parallel. When paralleled, there is no master unit and each unit adjusts its own power level for
best power sharing. Please refer to the following wiring instructions for your needs.
When selecting wiring, consider the following factors:
• Current carrying capacity of the wire
• Maximum wire length needed
• Maximum ambient temperature.
