Understanding protection grades and the documents worth preparing

Start with the scene

Not every location needs the same protection grade, because a covered garage differs from an open roadside post. The core idea is simple: the system adjusts to real conditions, so first sort the scene, then discuss the plan with care and avoid using one ruler for every single case.

Papers that prevent trouble

Before work begins, prepare a clear list of site drawings, power capacity notes, and the agreed protection grade. Writing the standard into the process avoids the middle-step errors that appear when teams improvise and guess. A written note lets the next person verify quickly instead of making a costly mistake.

A safe habit and Yantai service

Keep safety rules easy to follow so everyone respects them without confusion. Follow the manual and never modify parts on your own, since that voids the protection the grade was meant to provide. Dongshang New Energy provides local support across districts and keeps protection-grade basics available for residents. By turning these steps into a routine, site managers reduce avoidable faults and build lasting trust with drivers who simply want a safe, predictable place to plug in without surprises or delays.
