Moving parts of machinery can crush or cut off body parts when a person is close to them while they move. In off-grid and backup systems, a Sunny Island can start a generator automatically, so the generator's moving parts can begin moving without warning. Run the generator only with its safety equipment, and install, maintain and service it according to the manufacturer's specifications. Tracking mounts add load-bearing moving parts, actuators and controls that need more maintenance than fixed arrays. The NESC requires parts that move suddenly and could injure people nearby to be guarded or isolated, and requires pulleys and belts to be guarded per ANSI/ASME B15.1. When you lift and move heavy frames, such as an HVAC-mounted frame on a battery enclosure, stay clear of the moving parts to avoid being crushed.
<!-- review notes
sentence 1: support check: partial - Crush/sever from moving parts is stated, but not the generic 'machinery' or 'when close while they move' condition; examples are generator and HVAC frame.
sentence 2: support check: partial - Auto-start by Sunny Island is stated, but 'off-grid and backup systems' and 'without warning' are not in the passages.
sentence 6: support check: partial - Warning covers lifting and moving the HVAC-mounted frame and keeping clear, but 'heavy frames' generally and 'battery enclosure' are not stated.
sentence 1: review: partial - The passages say generator moving parts can crush or sever body parts and the HVAC frame warns of crushing by moving parts, but the general 'machinery' framing and the 'when close while they move' condition are not stated.

Applies to equipment parts that move suddenly and are likely to injure people nearby. Pulleys, belts and mechanical transmission machinery are guarded per ANSI/ASME B15.1:2000.
Install, maintain and work on a generator that the Sunny Island can start automatically according to the generator manufacturer's specifications, and operate it only with its safety equipment.
