for Electrical
Practices and
Wire Sizes
The Cautions, Warnings, and instructions in this section summarize the procedures necessary to
ensure an inverter installation complies with Underwriters Laboratories
®
guidelines.
WARNING: “Use 60/75°C Cu wire only” or equivalent.
WARNING: “Open Type Equipment.” For models L300P–900H to L300P–1320H.
WARNING: “Suitable for use on a circuit capable of delivering not more than 10,000 rms
symmetrical amperes, 240 V maximum.” For models with suffix L.
WARNING: “Suitable for use on a circuit capable of delivering not more than 10,000 rms
symmetrical amperes, 480 V maximum.” For models with suffix H.
