2.3 PE Connection and Leakage Current
Island detection method
• 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.
High leakage current!
Earth connection essential before connecting supply.
WARNING!
• 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.
No protection settings can be altered.
For Australia and New Zealand:
Electrical installation and maintenance shall be conducted by licensed
electrician and shall comply with Australia National Wiring Rules.
The island detection method for X1 series inverter is Active Frequency Drift
(AFD).
For United Kindom:

Danger.
Risk of electric shock!
Observe enclosed documentation.
The inverter can not be disposed together with the household waste.
Disposal information can be found in the enclosed documentation.
Do not operate this inverter until it is isolated from battery,mains
and on-site PV generation suppliers.
Danger to life due to high voltage.
There is residual voltage in the inverter which needs 5 min to
discharge.
• Wait 5 min before you open the upper lid or the DC lid.
