WARNING
• The grounding points on the enclosure are preered.
• Make sure that all the grounding points on the enclosure are equipotential connected when
there are multiple inverters.
• To improve the corrosion resistance of the terminal, you are recommended to apply silica gel
or paint on the ground terminal after installing the PE cable.
• The PE cable should be prepared by the customer.
• The M8 OT terminal should be prepared by customers.

DANGER
1. Conrm the following information before connecting the PV string to the inverter. Otherwise,
the inverter may be damaged permanently or even cause re and cause personal and
property losses.
• Make sure that sum of the max short circuit current of the strings per MPPT are within the
permissible range, and the max input voltage is within the permissible range.
• Make sure that the positive pole of the PV string connects to the PV+ of the inverter. And
the negative pole of the PV string connects to the PV- of the inverter.
2. Do not plug or unplug the connectors when the equipment is working.
WARNING
1. Connect the DC cables using the delivered PV connectors. The manufacturer shall not be
liable for the damage if other connectors are used.
2. The PV strings cannot be grounded. Ensure the minimum isolation resistance of the PV string
to the ground meets the minimum isolation resistance requirements before connecting the
PV string to the inverter.
3. The DC cable should be prepared by the customer.
