2.1 Important Safety Instructions
Danger!
Danger to life due to high voltages in the inverter!
All work must be carried out by qualified 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.
Caution!
Danger of burn injuries due to hot enclosure parts!
During operation, the upper lid of the enclosure and the enclosure
body may become hot.
Only touch the lower enclosure lid during operation.
Caution!
Possible damage to health as a result of the effects of radiation!
Do not stay closer than 20 cm to inverter for any length of time.
Warning！
Authorized service personnel must disconnect AC power from
inverter before attempting any maintenance or cleaning or
working on any circuits connected to inverter.
Prior to the application, please read this section carefully to ensure correct and
safe application. Please keep the user manual properly.
Accesories only together with the inverter shipment are recommanded here.
Otherwise may result in a risk of fire, electric shock, or injury to person.
Make sure that existing wiring is in good condition and that wire is not
undersized.
Do not disassemble any parts of inverter which are not mentioned in installation
guide. It contains no user-serviceable parts. See Warranty for instructions on
obtaining service. Attempting to service the inverter yourself may result in a risk
of electric shock or fire and will void your warranty.
The installation place should be away from humid or corrosive substance.
Authorized service personnel must use insulated tools when installing or
working with this equipment.
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 inverter couplers, the MAINS cables or when power is Battery cables
applied. After switching off the battery and Mains, always wait for 5minutes to let
the intermediate circuit capacitors discharge before unpluging battery inplug
and MAINS couplers.
When accessing the internal circuit of 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 before hand since the
capacitors require time to sufficiently discharge!
Measure the voltage between terminals + and - with a multi-meter UDCUDC
(impedance at least 1Mohm) to ensure that the device is discharged before
beginning work (35) inside the device.VDC
To protect the AC system,surge suppression devices (SPD type2) should be fitted
at the main incoming point of AC supply (at the custome’s cutout), located
between the inverter and the meter/distribution system; SPD (test impluse D1)
for signal line according to EN 61632-1.
04
WARNING !
Do not operate the inverter when the device is running.
WARNING !
Risk of electric shock!

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.
• 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.

Battery Safety Instructions
SolaX X1-AC Series inverter should be worked with high voltage battery, for the
specific parameters such as battery type, nominal voltage and nominal
capacity etc., please refer to section 4.2.
As accumulator batteries may contain potential electric shock and short-circuit
current danger, to avoid accidents that might be thus resulted, the following
warnings should be observed during battery replacement:
•
1: Do not wear watches, rings or similar metallic items.
2: Use insulated tools.
3: Put on rubber shoes and gloves.
4: Do not place metallic tools and similar metallic parts on the batteries.
5: Switch off load connected to the batteries before dismantling battery
connection terminals.
6: Only personal with proper expertise can carry out the maintenance of
accumulator batteries.
• 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 the RCD or RCM of type B is allowed
on the supply side of this product.
