UL® Cautions, Warnings, and Instructions

Wiring Warnings 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 SJ300–750H to SJ300–1500H.

Terminal Tightening Torque and Wire Size

WARNING: “Suitable for use on a circuit capable of delivering not more than 100,000 rms symmetrical amperes, 240 V maximum.” For models with suffix L.

WARNING: “Suitable for use on a circuit capable of delivering not more than 100,000 rms symmetrical amperes, 480 V maximum.” For models with suffix H.

The wire size range and tightening torque for field wiring terminals are presented in the table below.
