• Authorized service personnel must use insulated tools when installing or working
with this equipment.
• PV modules shall have an IEC 61730 class A rating.
PE Connection and leakage current
• The end-use application shall monitoring of the protective conductor by residual
current operated protective device (RCD) with rated fault current Ifn≤100mA
which automatically disconnects the device in case of a fault.
• DC differential currents are created (caused by insulation resistance and through
capacities of the PV generator). In order to prevent unwanted triggering during
operation, the rated residual current of the RCD has to be min100mA.
• The device is intended to connect to a PV generator with a capacitance limit of
approx 700nf.
High leakage current!
Earth connection essential before connecting supply.
WARNING!
• Incorrect grounding can cause physical injury, death or equipment malfunction
and increase electromagnetic interference.
• Make sure that grounding conductor is adequately sized as required by safety
regulations.
• Do not connect the ground terminals of the unit in series in case of a multiple
installation. This product can cause current with a d.c component, Where a residual
current operated protective (RCD) or monitoring (RCM) device is used for protection
in case of direct or indirect contact, only an RCD or RCM of type B is allowed
on the supply side of this product.
• For Australia and New Zealand:
The installation of inverter must fulfill Australia national Wiring rules AS/NZS3000,
AS/NZS4777.1 and AS/NZS5033.
Do not work on the solar inverter when the device is running.
WARNING!
• Never touch either the positive or negative pole of PV connecting device. And
never ever touch both at the same time.
Risk of electric shock!
WARNING!
• The unit contains capacitors that remain charged to a potentially lethal voltage
after the MAINS and PV supply has been disconnected.
• Hazardous voltage will present for up to 45 minutes after disconnection from
power supply.
• CAUTION-RISK of electric shock from energy stored in capacitor, never work on
the solar inverter couplers.,the MAINS cable, PV cables or the PV generator when
power is applied. After switching off the PV power and Mains, always wait for 15
minutes to let the intermediate circuit capacitors discharge before you unplug
DC input and MAINS couplers.
• When access to internal circuit of solar inverter, it is very important to wait 45
minutes before working on power circuit or demounting the electrolyte capacitors
inside the device. Do not open the device before hand since the capacitors
require this long to discharge sufficiently!
• 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.
2.4 EC Directives
This chapter follows the requirements of the European Low Voltage Directives,
which contains the safety instructions and conditions of acceptability for the
enduse system, which you must follow when installing, operating and servicing
the unit. If ignored, physical injury or death may follow, or damage may occur to
the unit. Read this instructions before you work on the unit. If you are unable to
understand the dangers, warnings, cautions or instructions, contact the
manufacture if an authorized service dealer before installing.,operating and
servicing the unit.
The grid connected inverter meets the requirement stipulated in Low Voltage
Directive (LVD) 2006/95/EC and Electromagnetic Compatibility (EMC) Directive
2004/108/EC. The unit is tested based on:
EN 50178:1997 EN 62109-1:2010 EN 62109-2:2011
VDE 0126-1-1:2006 VDE 4105:2011
In case of installation in PV system, startup of the unit (i.e. start of designated
operation) is prohibited until it is determined that the full system meets the
requirements stipulated in EC Directive (2006/95/EC,2004/108/EC, etc.)
The grid connected inverter leaves the factory completely connecting device
and ready for connection to the mains and PV supply. The unit shall be installed
in accordance with national wiring regulations. Compliance with safety regulations
depends upon installing and configuring system correctly, including using the
specified wirings. The system must be installed only by professional assemblers
who are familiar with requirements for safety and EMC. The assembler is responsible
for ensuring that the end system complies with all the relevant laws in the country
where it is to be used.
The individual subassembly of the system shall be interconnected by means of
the wiring methods outlined in national/international such as the National Electric
code (NFPA) No.70 or VDE regulation 0107.
