Safety Precautions
General Disclaimer
• The information in this quick installation guide is subject to
change due to product updates or other reasons. This guide
cannot replace the product labels or the safety precautions in
the user manual unless otherwise specified. All descriptions
here are for guidance only.
• Before installations, read through the quick installation guide.
For additional information, please see the user manual.
• All operations should be performed by trained and
knowledgeable technicians who are familiar with local
standards and safety regulations.
• Check the deliverables for correct model, complete contents,
and intact appearance. Contact the manufacturer if any
damage is found or any component is missing.
• Use insulating tools and wear personal protective equipment
when operating the equipment to ensure personal safety.
Wear anti-static gloves, clothes, and wrist strip when touching
electronic components to protect the inverter from damage.
The manufacturer shall not be liable for any damage caused by
static electricity.
• Strictly follow the installation, operation, and configuration
instructions in this guide and user manual. The manufacturer
shall not be liable for equipment damage or personal injury if
you do not follow the instructions.

WARNING
PV panel safety:
1. Ensure the component frames and the bracket system are
securely grounded.
2. Connect the DC cables using the delivered PV connectors. The
manufacturer shall not be liable for any equipment damage if
other connectors are used.
3. Ensure the DC cables are connected tightly, securely, and
correctly. Inappropriate wiring may cause poor contacts or
high impedances, and damage the inverter.
4. Measure the DC cable using the multimeter to avoid reverse
polarity connection. Also, the voltage should be under the
max DC input voltage. The manufacturer shall not be liable for
the any damage caused by reverse connection and extremely
high voltage.

5. The PV strings cannot be grounded. Ensure that the minimum
insulation resistance of the PV string to the ground meets
the minimum insulation resistance requirements before
connecting the PV string to the inverter. R=Max. Input
Voltage/30mA.
6. The PV modules used with the inverter must have an
IEC61730 class A rating.
Inverter safety:
1. The voltage and frequency at the connecting point should
meet the on-grid requirements.
2. Additional protective devices like circuit breakers or fuses are
recommended on the AC side.
Specification of the protective device should be at least 1.25
times the rated AC output rated current.
3. Make sure that all the groundings are tightly connected.
When there are multiple inverters, make sure that all the
grounding points on the enclosures are equipotential bonding.
4. Do not start the BACK-UP function if there is no battery in
the PV system. The manufacturer shall not be liable for the
risks caused by not following this rule.
5. Do not apply mechanical load to the terminals, otherwise the
terminals can be damaged.
6. All labels and warning marks should be visible after the
installation. Do not scrawl, damage, or cover any label on the
device.
7. Do not touch the running equipment to avoid being hurt as its
temperature may exceed 60°C. Do not install the equipment
at a place within children's reach.
8. Unauthorized dismantling or modification may damage the
equipment. the damage is not covered under the warranty.
9. 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 filter or a multi winding ferrite core to
the DC input cable or AC output cable of the inverter.
10. Warning labels on the inverter are as follows.
