Safety

This section deals with the basic safety instructions for using the device

This operator's manual contains safety notices that must be observed during installation and maintenance. Therefore, keep the operator's manual in a safe place for the entire life cycle of the device.

Include the operator's manual if you sell the device or set it up at another location.

Specify the material number or document number of the operator's manual to reorder the operator's manual (see half title).

Incorrect use or wrong operation might endanger operator or a third party and destroy the inverter or other properties.

To prevent the above circumstances from happening, the following precautions should be strictly abided by in the process of operation and maintenance. The detailed description will be provided in relevant chapter.

A warning sign contains signal words which are explained in the following table:

The device is a bidirectional converter. It is used for charging a DC link from a three-phase or split-phase AC distribution network and for feeding the AC network from the DC link's energy.

• The power and the energy flow direction can be adjustable in “on-grid mode”.
• The device draws sinusoidal current from the mains or delivers sinusoidal current to the mains. The power factor, also known as cosφ can be adjustable in “on-grid mode”.
• The power, the energy flow direction, the power factor are not adjustable but determined by the accumulated power in a microgrid in “off-grid mode”

Any use not listed under “Typical fields of application” contravenes the intended purpose. the seller is not liable for any ensuing damages, in particular for property damage, personal injury and loss of production. The operator bears all risks. The warranty is rendered null and void.

Impermissible uses include, for example:

• Use of incorrect components.
• Operation on mains voltage outside the specification.
• Faulty installation (e.g., cables reversed).
• Use in unauthorized installation position.
• Misuse by untrained personnel.
• Use in unsuitable environmental conditions:
  • Condensation, icing.
  • Conductive soiling.
  • Corrosive conditions (e.g. battery fumes, salt spray).
  • Voltages outside of overvoltage category III (max. 4 kV impulse withstand voltage).
  • Operation at more than 2000 m above sea level.
  • Outdoors.
  • Failure to observe pollution degree 2 environmental condition.
  • In an explosive environment.

This converter is only designed for commercial/industrial purposes, and it not supposed to be used as an energy saving device related to life support device. Consider the risk before using them for these purposes.

Energy storage inverter must be debugged and maintained by the Authorized persons designated by the manufacturer or its agent. Otherwise, it might endanger personal safety and result in device fault. Any damage against the device caused thereby will not fall into the warranty scope.

Authorized persons must be capable of understanding their tasks and recognizing potential dangers. Therefore, authorized persons must be trained and be familiar with the standards and regulations relevant to their tasks.

Authorized who meet the above conditions can:

1. Install the converter to the wall or a designed rack/cabinet;
2. Setup energy storage system as per customer’s requirement;
3. Conduct trial operation of energy storage system;
4. Operate, debug and maintain energy storage system.

The label on enclosure contains important information for safe operation to the inverter. Do NOT tear or damage it.

The label on enclosure should be clear and readable. If it is damaged or becomes vague, please replace it.

The device produces voltages that can endanger human life and health. These voltages occur both in the device as well as at the outputs of the device. The device's connection cables carry voltages that are life-threatening.

A person who comes into contact with live device parts may be killed or severely injured

The converter module is installed in an enclosed metal casing

• Only operate the device within the conditions described in technical specifications.
• The device must NOT be opened.
• Only operating personnel without pacemaker or implants may work in the operational site.
• For the electrical connection, use only cables that are in perfect condition and have the correct dimensions.
• Perform periodic electrical safety inspections according to country-specific requirements.
