2.2 DC Side:
Notice
• The information in this document is subject to change due to product updates or other
reasons. This manual cannot replace the product labels or the safety precaution unless
otherwise specied. All descriptions here are for guidance only.
• Before installations, read through the user manual to learn about the product and the
precautions.
• All installations should be performed by trained and knowledgeable technicians who are
familiar with local standards and safety regulations.
• Use insulating tools and wear personal protective equipment when operating the
equipment to ensure personal safety. Wear anti-static gloves, cloths, and wrist strips when
touching electron devices to protect the inverter from damage.
• Strictly follow the installation, operation, and conguration instructions in this manual. The

asp.
Notice
The inverters are designed and tested strictly complies with related safety rules. Read and
follow all the safety instructions and cautions before any operations. Improper operation
might cause personal injury or property damage as the inverters are electrical equipment.
DANGER
Connect the DC cables using the delivered DC connectors and terminals. The manufacturer
shall not be liable for the equipment damage if other connectors or terminals are used.
WARNING
• Ensure the component frames and the bracket system are securely grounded.
• Ensure the DC cables are connected tightly and securely.
• Measure the DC cable using the multimeter to avoid reverse polarity connection. Also, the
voltage should be under the permissible range.
• The PV modules used with the inverter must have an IEC61730 class A rating.
• If there are more than 3 PV strings on input side, an additional fuse installation will be
suggested.
• When exposed to sunlight, the PV array will generate very high voltage which can cause
electrical shock hazard. Please strictly follow the instruction we provided.

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.
8. The installation place of the inverter shall be far away from the living areas considering that
the vibration it has may bother the residents during its working.
9. 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.
