Safety
3 / 61
• Prior to the application, please read this section carefully to ensure correct and safe
application. Please keep the user manual properly.
• Accessories only together with the inverter shipment are recommend here .other- wise
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.
• PV modules shall have an IEC 61730 class A rating.
• Never touch either the positive or negative pole of PV connecting device. Strictly prohibit
touching both of them at the same time.
• The unit contains capacitors that remain charged to a potentially lethal voltage after the
MAINS , battery and PV supply has 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, Battery cables, PV cables or the PV generator when
power is applied. After switching off the PV , battery and Mains, always wait for 5minutes
to let the intermediate circuit capacitors discharge before unplug DC ,battery plug and
MAINS couplers.
• 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 beforehand since the capacitors require time sufficiently
discharge!
• Measure the voltage between terminals UDC+ and UDC- with a multi-meter(impedance
at least 1Mohm) to ensure that the device is discharged before beginning work (35VDC)
inside the device.
Surge protection devices (SPDs) for PV installation
Lightning will cause a damage either from a direct strike or from surges due to a nearby
Warning!
Warning!
Over-voltage protection with surge arresters should be provided when the PV power
system is installed.
The grid connected inverter is not fitted with SPDs in both PV input side and MAINS
