2.1 Important Safety Instructions
Danger!
Danger to life due to high voltage in the inverter!
All work must be carried out by qualified electrician.
The appliance is not to 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.
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.
Only touch the lower enclosure lid during operation.
Caution
!
Possible damage to health as a result of the effects of radiation!
Do not stay closer than 20 cm to inverter for any length of time.
Warning
！
Authorized service personnel must disconnect both AC power
from inverter before attempting any maintenance or cleaning or
working on any circuits connected to inverter.
Do not operate the inverter when the device is running.
Warning
!
Risk of electric shock!
Warning
!
Prior to the application, please read this section carefully to ensure correct and
safe application. Please keep the user manual properly.
Accesories only together with the inverter shipment are recommanded here.
Otherwise may result in a risk of fire, electric shock, or injury to person.
Make sure that existing wiring is in good condition and that 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 inverter 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.
The unit contains capacitors that remain charged to a potentially lethal voltage
after the MAINS and battery have been disconnected.
Hazardous voltage will present for up to 5 minutes after disconnection from
power supply.
CAUTION-RISK of electric shock from energy stored in capacitor, Never operate
on the inverter couplers, the MAINS cables or Battery cables when power is
applied. After switching off the battery and Mains, always wait for 5 minutes to
let the intermediate circuit capacitors discharge before disconnecting battery
plugs and MAINS cables.
When accessing the internal circuit of inverter, it is very important to wait 5
minutes before operating the power circuit or demounting the electrolyte
capacitors inside the device. Do not open the device before hand since the
capacitors
time to sufficiently discharge!
require
Measure the voltage between terminals UDC+ and UDC- with a multi-meter
(impedance at least 1Mohm, voltage must be less than 35VDC) to ensure that
the unit is discharged before starting to do any operation inside the device.
Lightning will cause a damage either from a direct strike or from surges due to a
nearby strike.
Specialists in lightning protection should be consulted during the end use
application.
Using appropriate external lightning protection, the effect of a direct lightning
strike into a building can be mitigated in a controlled way, and the lightning
current can be discharged into the ground.
Installation of SPDs to protect the inverter against mechanical damage and
excessive stress include a surge arrester in case of a building with external
lightning protection system (LPS) when separation distance is kept.
To protect the AC system, surge suppression devices (SPD type2) should be
fitted at the main incoming point of AC supply (at the consumer’s cutout),
located between the inverter and the meter/distribution system; SPD (test
impulse D1) for signal line according to EN 61632-1.
