5 Installation
5.1 Installation Requirements
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. 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.
7. Install the equipment at a height that is convenient for operation and maintenance, electrical
connections, and checking indicators and labels.

5.2 Inverter Installation
5.2.2 Installing the Inverter
5.2.1 Moving the Inverter
CAUTION
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.
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.
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.

6 Electrical Connection
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
before any electrical connections. Do not work with power on. Otherwise, an electric shock
may occur.
• Perform electrical connections in compliance with local laws and regulations. Including
operations, cables, and component specications.
• If the cable bears too much tension, the connection may be poor. Reserve a certain length of
the cable before connecting it to the inverter cable port.
Only for Australia.
