2. Safety
2.1 Appropriate Usage
This series inverter is designed and tested in accordance with international safety requirements. However,
certain safety precautions must be taken when installing and operating this inverter. The installer must read
and follow all instructions, cautions and warnings in this installation manual.
- All operations including transport, installation, start-up and maintenance, must be carried out by qualified,
trained personnel.
- The electrical installation & maintenance of the inverter shall be conducted by a licensed electrician and
shall comply with local wiring rules and regulations.
- Before installation, check the unit to ensure it is free of any transport or handling damage, which could
affect insulation integrity or safety clearances. Choose the installation location carefully and adhere to
specified cooling requirements. Unauthorized removal of necessary protections, improper use, incorrect
installation and operation may lead to serious safety and shock hazards or equipment damage.
- Before connecting the inverter to the power distribution grid, contact the local power distribution grid
company to get appropriate approvals. This connection must be made only by qualified technical
personnel.
- Do not install the equipment in adverse environmental conditions such as in close proximity to flammable
or explosive substances; in a corrosive environment; where there is exposure to extreme high or low
temperatures; or where humidity is high.
- Do not use the equipment when the safety devices do not work or are disabled.
- Use personal protective equipment, including gloves and eye protection during the installation.
- Inform the manufacturer about non-standard installation conditions.
- Do not use the equipment if any operating anomalies are found. Avoid temporary repairs.
- All repairs should be carried out using only approved spare parts, which must be installed in accordance
with their intended use and by a licensed contractor or authorized service representative.
- Liabilities arising from commercial components are delegated to their respective manufacturers.
- Any time the inverter has been disconnected from the public network, please be extremely cautious as
3
some components can retain charge sufficient to create a shock hazard. Prior to touching any part of the
inverter please ensure surfaces and equipment are under touch safe temperatures and voltage potentials
before proceeding.
2.2 PE Connection and Leakage Current
- The end-use application shall monitor the protective conductor by residual current operated protective
device (RCD) with rated fault current Ifn≤280mA 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.
WARNING!
High leakage current! Earth connection essential before connecting supply.
- Incorrect grounding can cause physical injury, death or equipment malfunction and increase
electromagnetic interference.
- 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 DC component, where a residual current operated protective device (RCD) or
monitoring device (RCM) 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 UK
- 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 60634-7-712.
- No protection settings can be altered.
- User shall ensure that the equipment is so installed, designed and operated to maintain at all times
compliance with requirements of ESQCR22(1)(a).
For AU
- Electrical installation and maintenance shall be conducted by licensed electrician and shall comply with
Australia National Wiring Rules.
2.3 Surge Protection Devices (SPDs) for PV Installation
WARNING!
Over-voltage protection with surge arresters should be provided when the PV power system is installed. The
grid connected inverter is not fitted with SPDs in both PV input side and mains side.
Lightning will cause damage either from a direct strike or from surges due to a nearby strike.
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. Surges may impact on both the PV array
conduction and the AC cables leading to the building. Specialists in lightning protection should be consulted
4
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 fitted 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 is required for surge protection for
electrical devices.
To protect the AC system, surge suppression devices (SPD type2) should be fitted 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.
Avoiding the creation of loops in the system. This requirement for short 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 across their terminals is typically below 30 volts.
