5.1 Installation Requirements
Installation Environment Requirements
Children No Touch
1. Do not install the equipment in a place near ammable, explosive, or corrosive materials.
2. Install the equipment on a surface that is solid enough to bear the inverter weight.
3. Install the equipment in a well-ventilated place to ensure good dissipation. Also, the
installation space should be large enough for operations.
4. The equipment with a high ingress protection rating can be installed indoors or outdoors.
The temperature and humidity at the installation site should be within the appropriate range.
5. Install the equipment in a sheltered place to avoid direct sunlight, rain, and snow. Build a
sunshade if it is needed.
6. Install the equipment in a well-ventilated place to ensure good dissipation. Also, the
installation space should be large enough for operations.
7. Do not install the equipment in a place that is easy to touch, especially within children’s
reach. High temperature exists when the equipment is working. Do not touch the surface to
avoid burning.
8. Install the equipment at a height that is convenient for operation and maintenance, electrical
connections, and checking indicators and labels.
9. The altitude to install the inverter shall be lower than the maximum working altitude 4000m.
10.The inverter is easy to be corroded when installed in salt areas. Please consult the inverter
manufacturer before installing it outdoors in salt areas. A salt area refers to the region
within 1000m oshore or aected by the sea breeze. The area prone to the sea breeze varies
depending on weather conditions (e.g. typhoon, monsoon) or terrain (such as dams and
hills).
11.Install the inverter away from high magnetic eld to avoid electromagnetic interference.If
there is any radio or wireless communication equipment below 30MHz near the inverter, you
have to:
• Install the inverter at least 30m far away from the wireless equipment.
• Add a low pass EMI lter or a multi winding ferrite core to the DC input cable or AC output
cable of the inverter.

5.2 Inverter Installation
5.2.1 Moving the Inverter
CAUTION
• Operations such as transportation, turnover, installation and so on must meet the
requirements of the laws and regulations of the country or region where it is located.
• Move the inverter to the site before installation. Follow the instructions below to avoid
personal injury or equipment damage.
1. Consider the weight of the equipment before moving it. Assign enough personnel to
move the equipment to avoid personal injury.
2. Wear safety gloves to avoid personal injury.
3. Keep balance to avoid falling down when moving the equipment.
Step 1 Put the mounting plate on the wall or the support horizontally and mark positions for
drilling holes.
Step 2 Drill holes to a depth of 80mm using the hammer drill. The diameter of the drill bit
should be 10mm.
Step 3 Secure the mounting plate using the expansion bolts.
Step 4 (Only for Australia.) Install the DC switch lock.
Step 5 Install the inverter on the mounting plate.
Step 6 Install the anti-theft lock.
NOTICE
• Avoid the water pipes and cables buried in the wall when drilling holes.
• Wear goggles and a dust mask to prevent the dust from being inhaled or contacting eyes
when drilling holes.
• The DC switch lock is prepared by the customer.
• Make sure the inverter is rmly installed in case of falling down.

6.1 Safety Precaution
NOTICE
• Wear personal protective equipment like safety shoes, safety gloves, and insulating gloves
during electrical connections.
• All electrical connections should be performed by qualied professionals.
• Cable colors in this document are for reference only. The cable specications shall meet local
laws and regulations.
DANGER
• Disconnect the DC switch and the AC output switch of the inverter to power o the inverter
