Enclosure door open

This symptom means a door on an inverter or equipment enclosure was opened, often while the unit was running. On the SMA Sunny Central CP-XT it shows up as error 9008, which means doors were opened during operation, and SMA advises contacting its Service Line. Battery enclosures such as the Tesla Megapack report it through a door switch point in SCADA when one or more doors are open. Check first that the door status reading is correct when the door is actually open and when it is closed, so you can rule out a faulty door switch or status indication. Before anyone opens an enclosure door, complete the site door access checklist so that site communication and lockout of circuits are done first. The procedures for opening an enclosure door warn of arc flash risk, and some equipment manuals list conditions in which the doors must not be opened at all.

<!-- review notes

• sentence 1: support check: partial - Passages show doors opened during operation (SMA) and Megapack door open, but 'inverter or equipment enclosure, often while running' generalizes; only the SMA case is about running.
• sentence 3: support check: partial - The Megapack Door Switch Open DNP3 point is stated, but 'Battery enclosures such as' generalization and 'SCADA' are not explicitly stated (DNP3 point only).
• sentence 4: support check: partial - The passage says confirm door status displays accurately when open or closed, but the purpose of ruling out a faulty switch and 'check first' are not stated.
• sentence 1: review: partial - The passages back a door being opened on an SMA inverter during operation and on a Megapack, but the 'often while running' frequency and the general 'equipment enclosure' scope are generalizations.
• sentence 4: review: partial - The passage says to confirm the door status displays accurately when open or closed, but it does not give the purpose (ruling out a faulty door switch or indication) or say this is the first check. -->
