• Failure to follow the operation instructions and safety precautions on the product and in this document
• Equipment damage due to force majeure, such as earthquakes, fire, and storms
• Damage caused during transportation by the customer
• Damage caused by storage conditions that do not meet the requirements specified in related documents

General Requirements

Do not work with power on during installation.

• Do not install, use, or operate outdoor equipment and cables (including but not limited to moving equipment, operating equipment and cables, inserting connectors to or removing connectors from signal ports connected to outdoor facilities, working at heights, and performing outdoor installation) in harsh weather conditions such as lightning, rain, snow, and level 6 or stronger wind.
• After installing the equipment, remove idle packing materials such as cartons, foam, plastics, and cable ties from the equipment area.
• In the case of a fire, immediately leave the building or the equipment area, and turn on the fire alarm bell or make an emergency call. Do not enter the building on fire in any case.
• Do not scrawl, damage, or block any warning label on the equipment.
• Tighten screws using tools when installing the equipment.
• Understand the components and functioning of a grid-tied PV power system and relevant local standards.
• Repaint any paint scratches caused during equipment transportation or installation in a timely manner. Equipment with scratches cannot be exposed to an outdoor environment for a long period of time.
• Do not open the host panel of the equipment.
• Without prior consent from the manufacturer, do not alter the internal structure or installation procedure of the equipment.
• Ensure that battery terminal components are not affected during transportation. Do not hoist or move batteries by using battery terminal bolts.

Personal Safety

• Wear proper personal protective equipment (PPE) during operation. If there is a probability of personal injury or equipment damage, immediately stop the operations, report the case to the supervisor, and take feasible protective measures.
• Use tools correctly to avoid hurting people or damaging the equipment.
• Do not touch the energized equipment, as the enclosure is hot.
• To ensure personal safety and normal use of the equipment, the equipment must be reliably grounded before use.
• When a battery is faulty, the temperature may exceed the burn threshold of the touchable surface. Therefore, avoid touching the battery.
• Do not disassemble or damage the battery. The released electrolyte is harmful to your skin and eyes. Avoid contact with the electrolyte.
• Do not place irrelevant objects on the top of the equipment or insert them into any position of the equipment.
• Do not place inflammables around the equipment.
• To prevent explosions and body injury, do not place batteries in a fire.
• Do not place the battery module in water or other liquids.
• Do not short-circuit wiring terminals of batteries. Short circuits can cause a fire.
• Batteries may cause electric shocks and high short-circuit currents. When using the battery, pay attention to the following points:

  (a) Remove any metal objects from yourself, such as watches and rings.

  (b) Use tools with insulated handles.

  (c) Wear rubber gloves and boots.

  (d) Do not place tools or metal parts on top of batteries.

  (e) Before connecting or disconnecting battery terminals, disconnect the charging power supply.

  (f) Check whether batteries are accidentally grounded. If it is accidentally grounded, remove the power supply from the ground. Touching any part of a grounded battery can cause an electric shock. If these grounding points are removed during installation and maintenance, the possibility of electric shocks can be reduced.

• Do not use water to clean electrical components inside or outside of a cabinet.
• Do not stand on, lean on, or sit on the top of the equipment.
• Do not damage the modules of the equipment.
