2 Safety
2.1 Appropriate Usage
The X1 Series are PV inverters which can convert the DC current of the PV generator
into AC current and feed it into the public grid.
* Surge protection devices (SPDs) for PV installation
Over-voltage protection with surge arresters should be provided
when the PV power system is installed.
The grid connected inverter is tted with SPDs in MAINS side.
WARNING !
Induced surges are the most likely cause of lightning damage in majority or
installations, especially in rural areas where electricity is usually provided by long
overhead lines. Surge may be included on both the PV array conduction and the
AC cables leading to the building.
Specialists in lightning protection should be consulted during the end use
application. Using appropriate external lightning protection, the effect of a direct
lightning strike into a building can be mitigated in a controlled way, and the
lightning current can be discharged into the ground.
Installation of SPDs to protect the inverter against mechanical damage and
excessive stress include a surge arrester in case of a building with external
lightning protection system (LPS) when separation distance is kept.
To protect the DC system, surge suppression device (SPD type2) should be tted
at the inverter end of the DC cabling and at the array located between the
inverter and the PV generator, if the voltage protection level (VP) of the surge
arresters is greater than 1100V, an additional SPD type 3 required for surge
protection for electrical devices.
To protect the AC system, surge suppression devices (SPD type2) should be
tted at the main incoming point of AC supply (at the consumer’s cutout),
located between the inverter and the meter/ distribution system; SPD (test
impulse D1) for signal line according to EN 61632-1.
All DC cables should be installed to provide as short a run as possible, and
positive and negative cables of the string or main DC supply should be bundled
together. Avoid creating loops in the system. This requirement forshort runs
and bundling includes any associated earth bundling conductors.
Spark gap devices are not suitable to be used in DC circuits once conducting,
they won’t stop conducting until the voltage passes through their terminals
typically less than 30 volts.
Lightning will cause a damage either from a direct strike or from surges due to a
nearby strike.

Anti-Islanding Effect
►
Islanding effect is a special phenomenon that grid-connected PV system
still supply power to the nearby grid when electrical grid power is no
longer present. It is dangerous for maintenance personnel and the public.
X1 series provide Active Frequency Drift(AFD) to prevent islanding effect.

All work must be carried out by qualied electrician.
The appliance is not to be used by children or persons with
reduced physical sensory or mental capabilities, or lack of
experience and knowledge, unless they have been given
supervision or instruction.
Children should be supervised to ensure that they do not play
with the appliance.
WARNING!
Authorized service personnel must disconnect both AC and DC
power from X1 series before attempting any maintenance or
cleaning or working on any circuits connected to the X1 series.
Hazardous voltage will present for up to 5 minutes after
disconnection from power supply.
WARNING!
CAUTION-RISK of electric shock from energy stored in capacitor. Never operate on
the solar inverter couplers, The MAINS cables, PV cables or the PV generator when
power is applied. After switching off the PV and Mains, always wait for 5minutes to
let the intermediate circuit capacitors discharge before you unplug DC and MAINS
couplers.
When accessing the internal circuit of solar inverter, it is very important to wait 5
minutes before operating the power circuit or demounting the electrolyte
capacitors inside the device. Do not open the device beforehand since the
capacitors require time to suffciently discharge!
Measure the voltage between terminals UDC+ and UDC- with a multi-meter
(impedance at least 1Mohm) to ensure that the device has totally discharged.

PE Connection and Leakage Current
• The inverter incorporates a certied internal Residual Current Device (RCD)
in order to protect against possible electrocution and re hazard in case of a
malfunction in the cables or the inverter. There are two trip thresholds for the RCD
as required for certication (IEC 62109-2: 2011). The default value for eletrocution
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 eletric code. It recommends using a type-A RCD. The
recommended RCD values is 300mA unless a lower value is required
by the specic local electric codes. When required by local regulations, the use of
an RCD type B is permitted.
The device is intended to connect to a PV generator with a capacitance limit of
approx 700nf.
