Anti-Islanding Effect

►

• Islanding effect is a special phenomenon that grid-connected system still

supply power to the nearby grid when the voltage loss is happened in the

power system. It is dangerous for maintenance personnel and the public.

• X1-AC seires inverter provide Active Frequency Drift(AFD) to prevent

islanding effect.

►

PE Connection and Leakage Current

• The inverter incorporates a certified internal Residual Current Device (RCD)

in order to protect against possible electrocution and fire hazard in case of a

malfunction in the cables or inverter. There are two trip thresholds for the RCD

as required for certification (IEC 62109-2:2011). The default value for eletrocution

protection is 30mA, and for slow rising current is 300mA.

• If an external RCD is required by local regulations, check which type of RCD

is required for relevant eletric code. It recommends using a type-A RCD. The

recommended RCD values is 100mA or 300mA 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.

WARNING !

High leakage current!

Earth connection essential before connecting supply.

For United Kingdom

• The installation that connects the equipment to the supply terminals shall

comply with the requirements of BS 7671.

• No protection settings can be altered.
