WARNING!
WARNING!
CAUTION!
Danger of burn injuries due to hot enclosure parts!
• During operation, the upper lid of the enclosure and the
enclosure body may become hot.
Possible damage to health as a result of the effects of
radiation!
• Pregnant women and kids should not stay close to the
inverter.
Grounding the PV generator.
•Comply with the local requirements for grounding the PV
modules and the PV generator. We recommend
connecting the generator frame and other electrically
conductive surfaces in a manner which ensures
continuous conduction and grounding these in order to
produce optimal protection of system and persons.
•Ensure input DC voltage ≤Max. DC voltage. Over voltage
may cause permanent damage to inverter or other
losses, which will not be included in warranty!
• Authorized service personnel must disconnect both AC
and DC power from X1 series before attempting any
maintenance or cleaning or working on any circuits
connected to the X1 series.
• Prior to the application, please read this section carefully to ensure
correct and safe application. Please keep the user manual properly.
•Only use attachments recommended or sold by us. Otherwise it may
result in a risk of fire, electric shock, or injury to person.
• Make sure that the existing wiring is in good condition and that the wire
is not undersized.
• Do not disassemble any parts of inverter which are not mentioned in
installation guide. It contains no user-serviceable parts. See Warranty
for instructions on obtaining service. Attempting to service the X1 Series
inverter by yourself may result in a risk of electric shock or fire and will
void your warranty. Keep away from flammable, explosive materials to
avoid fire disaster. The installation place should be away from humid or
corrosive substance. Authorized service personnel must use insulated
tools when installing or working with this equipment.
All DC cables should be installed as short as possible, and positive and
negative cables of the string or main DC supply should be bundled together.
Avoid creating loops in the system. This requirement for short runs and
bundling includes any associated earth bundling conductors.
Spark gap devices are not suitable to be used in DC circuits once
conducting, they won't stop conducting until the voltage passes through their
terminals typically less than 30 volts.
Anti-Islanding Effect
Islanding effect is a special phenomenon that the grid-connected PV system
still supply power to the nearby grid when electrical grid power is no longer
present. It is dangerous for maintenance personnel and the public. X1 series
provide Active Frequency Drift (AFD) to prevent the islanding effect.
DANGER!
Danger to life due to high voltages in the inverter!
• All work must be carried out by qualified electrician.
• The appliance should not be used by children or persons
with reduced physical sensory or mental capabilities, or
lack of experience and knowledge, unless they have
been given supervision or instruction.
• Children should be supervised to ensure that they do not
play with the appliance.
