Why spacing gets overlooked
Safety spacing is easy to dismiss until a real case appears. The useful rule is that one careful measurement avoids repeated fixes later. New users are advised to spend two minutes reading the notice on first use, because the few minutes invested upfront prevent the far costlier corrections that a neglected margin tends to require.
Signals that deserve attention
Some equipment changes are not urgent but worth recording. A practical standard is to leave spare margin, which lowers later cost. When uncertain, asking one extra question costs less than guessing wrong, and keeping a short log of observed changes helps the next technician act quickly and correctly.
Dongshang New Energy's reminder
Many disputes start not from complex technology but from unclear responsibility. Writing the boundary into an agreement protects both the service side and the user. Dongshang New Energy operates across Yantai districts and recommends aligning on responsibility before work begins, so that everyone shares the same clear expectations from day one.
The bottom line is that a small measured margin today prevents an awkward, costly correction tomorrow. Spelling out responsibility in writing turns a vague worry into a managed detail that both sides can rely on with confidence.
