Safety

DANGER

Consequence: Electric shock or injury from unexpected system operation

Avoidance: Turn OFF system power at the distribution board and wait 5 minutes or more before starting (general precaution G-D02; not restated per-cover in source §1.3.6, but applies whenever a gantry cover is open)

WARNING

Hazard: Cover mounting screws left loose after finishing work

Consequence: The cover can open, fall, or strike nearby objects — injury or equipment damage, especially with the gantry tilted

Avoidance: Confirm all 4 M4 screws are tightened firmly before returning the system to service (general precaution G-W11)
