2.3 PE Connection and Leakage Current

• The end-use application shall monitor the protective conductor by residual
current operated protective device (RCD) with rated fault current Ifn≤240mA
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 min 240mA.
The device is intended to connect to a PV generator with a capacitance limit of
approx 700nf.
WARNING
!
High leakage current!
Earth connection essential before connecting supply.
• Incorrect grounding can cause physical injury, death or equipment malfunction
and increase electromagnetic.
• 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.
• Never touch either the positive or negative pole of PV or battery 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 solar inverter couplers, 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
you unplug DC ,battery inplug and MAINS couplers.
• When access to internal circuit of solar inverter, it is very important to wait 45
minutes before operating the power circuit or demounting the electrolyte capacitors
inside the device. Do not open the device before hand since the capacitors
require long time 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
endues 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 test based on:
EN 50178:1997 EN 62109-1:2010
VDE 0126-1-1:2006 VDE 4105:2011
In case if 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 leave 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 assembly 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.
