Inverter surfaces get hot during normal operation, and touching them can burn you. The heat sink and the surfaces around it are the main danger, and they stay hot for some time after the unit stops running. Do not touch the product while it is running, and let it cool down enough before you start any work. SMA manuals say to wait 30 minutes for the surface to cool enough. Mount the inverter where nobody can touch it by accident, and follow the hot-surface safety messages on the unit.
<!-- review notes
- sentence 2: support check: partial - Heat sink and peripheral surfaces and 'shortly after operation' are stated, but not that they are the main danger or that they stay hot for some time.

c1 drafted · lead
Avoid hot surface contact proposed
CPS and Solectria manuals name the heat sink and surrounding surfaces, during operation and shortly after it; SMA manuals say not to touch the product while it is running.
c2 drafted · lead
Cool-down wait before work proposed
SMA inverter manuals give a 30-minute wait for the surface to cool enough before work.
c3 drafted · lead
Inaccessible equipment mounting proposed
Scope: products Sunny Tripower TL-US, Sunny Highpower PEAK3, Sunny Boy 3.0-7.7-US-41 proposed, Sunny Boy 3.0-7.7-US-40 proposed
Mount the inverter where people cannot touch it by accident.
review note: support check: partial - Passages state mounting so the inverter can't be touched inadvertently, but they don't mention the listed product IDs, so the scope isn't confirmed.

Observe equipment safety labels proposed
Scope: products Sunny Tripower TL-US, Sunny Highpower PEAK3, Sunny Boy 3.0-7.7-US-41 proposed, Sunny Boy 3.0-7.7-US-40 proposed
Follow the hot-surface safety messages on the inverter. The label is explained as 'Beware of hot surface'.
review note: support check: partial - Passages say to observe the safety messages on the inverter, but the 'Beware of hot surface' label explanation isn't in these passages and the product scope isn't stated.
