IMPORTANT SAFETY INSTRUCTIONS


Keep the manual for future reference.

This section contains safety information that must be observed at all times when working.

The product has been designed and tested in accordance with international safety requirements. As with all electrical or electronical devices, there are residual risks despite careful construction. To prevent personal injury and property damage and to ensure long-term operation of the product, read this section carefully and observe all safety information at all times.

DANGER

Danger to life due to electric shock when live components or DC cables are touched

The DC cables connected to a battery may be live. Touching live DC cables results in death or serious injury due to electric shock.

  1. Disconnect the product and battery from voltage sources and make sure it cannot be reconnected before working on the device.
  2. Wait five minutes before working on the inverter.
  3. Observe all safety information of the battery manufacturer.
  4. Do not touch non-insulated parts or cables.
  5. Do not remove the terminal block with the connected DC conductors from the slot under load.
  6. Wear suitable personal protective equipment for all work on the product.

DANGER

Danger to life due to electric shock in case of overvoltages and if surge protection is missing

Overvoltages (e. g. in the event of a flash of lightning) can be further conducted into the building and to other connected devices in the same network via the network cables or other data cables if there is no surge protection. Touching live parts and cables results in death or lethal injuries due to electric shock.

  1. Ensure that all devices in the same network and the battery are integrated into the existing surge protection.
  2. When laying the network cables or other data cables outdoors, it must be ensured that a suitable surge protection device is provided at the transition point of the cable from the product or the battery outdoors to the inside of a building.
  3. The Ethernet interface of the product is classified as "TNV-1" and offers protection against overvoltages of up to 1.5 kV.

WARNING

Danger to life due to fire or explosion

In rare cases, an explosive gas mixture can be generated inside the product under fault conditions. In this state, switching operations can cause a fire inside the product or explosion. Death or lethal injuries due to hot or flying debris can result.

  1. In the event of a fault, do not perform any direct actions on the product.
  2. Ensure that unauthorized persons have no access to the product.
  3. Disconnect the battery from the product via an external disconnection device.
  4. Disconnect the AC circuit breaker, or keep it disconnected in case it has already tripped, and secure it against reconnection.
  5. Only perform work on the product (e.g., troubleshooting, repair work) when wearing personal protective equipment for handling of hazardous substances (e.g., safety gloves, eye and face protection, respiratory protection).

WARNING

Danger to life due to fire or explosion when batteries are fully discharged

A fire may occur due to incorrect charging of fully discharged batteries. This can result in death or serious injury.

  1. Before commissioning the system, verify that the battery is not fully discharged.
  2. Do not commission the system if the battery is fully discharged.
  3. If the battery is fully discharged, contact the battery manufacturer for further proceedings.
  4. Only charge fully discharged batteries as instructed by the battery manufacturer.

WARNING

Risk of injury due to toxic substances, gases and dusts.

In rare cases, damages to electronic components can result in the formation of toxic substances, gases or dusts inside the product. Touching toxic substances and inhaling toxic gases and dusts can cause skin irritation, burns or poisoning, trouble breathing and nausea.

  1. Only perform work on the product (e.g., troubleshooting, repair work) when wearing personal protective equipment for handling of hazardous substances (e.g., safety gloves, eye and face protection, respiratory protection).
  2. Ensure that unauthorized persons have no access to the product.

WARNING

Danger to life due to burns caused by electric arcs through short-circuit currents

Short-circuit currents in the battery can cause heat build-up and electric arcs. Heat build-up and electric arcs may result in lethal injuries due to burns.

  1. Disconnect the battery from all voltages sources prior to performing any work on the battery.
  2. Observe all safety information of the battery manufacturer.

WARNING

Danger to life due to electric shock from destruction of the measuring device due to overvoltage

Overvoltage can damage a measuring device and result in voltage being present in the enclosure of the measuring device. Touching the live enclosure of the measuring device results in death or lethal injuries due to electric shock.

  1. Only use measuring devices with a DC input voltage range of 600 V or higher.

CAUTION

Risk of burns from hot surfaces

The surface of the inverter can get very hot. Touching the surface can result in burns.

  1. Mount the inverter in such a way that it cannot be touched inadvertently.
  2. Do not touch hot surfaces.
  3. Wait 30 minutes for the surface to cool sufficiently.
  4. Observe the safety messages on the inverter.

CAUTION

Risk of injury due to weight of product

Injuries may result if the product is lifted incorrectly or dropped while being transported or mounted.

  1. Transport and lift the product carefully. Take the weight of the product into account.
  2. Wear suitable personal protective equipment for all work on the product.

NOTICE

Damage to the enclosure seal in subfreezing conditions

If you open the product or disconnect the Power Unit and Connection Unit when temperatures are below freezing, the enclosure seals can be damaged. Moisture can penetrate the product and damage it.

  1. Only open the product if the ambient temperature is not below 0°C.
  2. If a layer of ice has formed on the enclosure seal when temperatures are below freezing, remove it prior to opening the product (e.g. by melting the ice with warm air).
  3. Do not disassemble the Power Unit and Connection Unit unless the ambient temperature is at least 0°C and conditions are frost-free.

NOTICE

Damage to the product due to sand, dust and moisture ingress

Sand, dust and moisture penetration can damage the product and impair its functionality.

  1. Only open the product if the humidity is within the thresholds and the environment is free of sand and dust.
  2. Do not open the product during a dust storm or precipitation.

NOTICE

Damage to the inverter due to electrostatic discharge

Touching electronic components can cause damage to or destroy the inverter through electrostatic discharge.

  1. Ground yourself before touching any component.

NOTICE

Damage to the product due to cleaning agents

The use of cleaning agents may cause damage to the product and its components.

  1. Clean the product and all its components only with a cloth moistened with clear water.

Change to the names and units of grid parameters to comply with the grid-connection requirements in accordance with Regulation (EU) 2016/631 (valid from April 27, 2019)

To comply with the EU grid-connection requirements (valid from April 27, 2019) the names and units of grid parameters were changed. This change is valid from firmware version ≥ 3.00.00.R if a country data set for fulfilling the EU grid-connection requirements (valid from 2019-04-27) is set. Names and units of grid parameters for inverters with firmware version ≤ 2.99.99.R are not affected by this change and remain valid. This also applies from firmware version ≥ 3.00.00.R if a country data set that is valid for countries outside the EU is set.
