A302 identifies the 24 VDC input version. The B2 suffix selects the 110 VAC, 60 Hz output and the TYPE-2 US receptacle arrangement shown above. Match both input and output ratings to the intended equipment.
The 300 W figure is the surge rating, not the normal load rating. No surge duration is specified for this model. Check that the connected load is suitable for a modified sine wave supply.
The 150 W rating is subject to the separate load-duration and temperature limits below; it is not an unlimited-duration 150 W operating guarantee.

Use the correct DC polarity and a connection rated for the actual current. The input ranges and low-battery protection thresholds are separate specifications; a shutdown threshold is not a guaranteed full-power input rating.
The listed fuse arrangement describes this inverter and its specified leads. Do not substitute a lower-rated vehicle outlet or lead for the required battery connection.

Overload protection is listed as a feature. A quantitative overload trip or automatic restart characteristic is not specified for this model.
A short circuit shuts off the output; automatic recovery is not specified. Remove the fault and check the inverter before returning it to service.

Install with unobstructed ventilation. Keep the inverter away from direct sunlight, heat sources, children, water, moisture, oil, grease and flammable materials.
The separate derating graph limits output to 70% of rating from 0 to 20°C and reduces it to 30% at 40°C. Its load limit must also be observed alongside the duration chart.
Use the lower applicable thermal and duration limit. The continuous-duty reference is 90 W before any stricter temperature derating; the 150 W table rating and the specification-table temperature entry do not override these operating charts. Confirm the intended operating point if it falls outside their combined limits.
