PE Connection and Leakage Current
•
All inverters incorporate a certified internal Residual Current Device(RCD) in
order to protect against possible electrocution and fire hazard in case of a
malfunction in the PV array, cables or inverter. There are 2 trip thresholds for
the RCD as required for certification (IEC 62109-2:2011). The default value for
electrocution protection is 30 mA, and for slow rising current is 300 mA.
• If an external RCD is required by local regulations, check which type of RCD is
required for relevant electric code. It recommends using a type-A RCD. The
recommended RCD values is 100 mA or 300 mA unless a lower value is required
by the specific local electric codes. When required by local regulations, the use
of an RCD type B is permitted.
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.
For United Kingdom
• The installation that connects the equipment to the supply terminals shall
comply with the requirements of BS 7671.
• Electrical installation of PV system shall comply with requirements of BS 7671
and IEC 60364-7-712.
• No protection settings can be altered.
• User shall ensure that equipment is so installed, designed and operated to
maintain at all times compliance with the requirements of ESQCR22(1)(a).
For Australia and New Zealand
• Electrical installation and maintenance shall be conducted by licensed
electrician and shall comply with Australia National Wiring Rules.

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 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.
