Safety Information

This section contains safety information that must be observed at all times when working on or with the product.

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 high voltages of the PV modules

When exposed to sunlight, the PV modules generate dangerous DC voltage which is present in the DC conductors. Touching the DC conductors can lead to lethal electric shocks. If you disconnect the DC connectors from the inverter under load, an electric arc may occur leading to electric shock and burns.

  1. Do not touch uninsulated cable ends.
  2. Do not touch the DC conductors.
  3. Do not open the inverter and the Sunny Multigate.
  4. Disconnect the inverter from all voltage sources before performing any work on it ( > Disconnecting the Inverter from Voltage Sources).
  5. Before working on the Sunny Multigate, always disconnect it from all voltage sources ( > Disconnecting the Sunny Multigate from Voltage Sources).
  6. Follow the instructions precisely.
  7. Observe the warning messages on the inverter and the Sunny Multigate.

DANGER

Risk of electric shock due to ground fault

If a ground fault occurs, parts of the system may still be live. Touching live components can lead to lethal electric shocks.

  1. Prior to touching any components, always disconnect the inverter from all voltage sources as described in this document ( > Disconnecting the Inverter from Voltage Sources).
  2. Prior to touching any components, always disconnect the Sunny Multigate from all voltage sources as described in this document ( > Disconnecting the Sunny Multigate from Voltage Sources).

DANGER

Risk of electric shock due to damaged devices

Operating a damaged inverter or Sunny Multigate can lead to hazardous situations that result in lethal electric shocks.

  1. Only operate the inverter and the Sunny Multigate provided that they are in safe and full working order.
  2. Regularly check for visible damage.

WARNING

Risk of burns due to hot surfaces

The surfaces of the inverter and the Sunny Multigate 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 ten minutes for the surface to cool sufficiently before performing any work on the inverter.
  4. Observe the warning messages on the inverter and the Sunny Multigate.

NOTICE

Damage to the inverter due to moisture and dust intrusion

Dust or moisture intrusion can damage the inverter and impair its functionality.

  1. Seal all inverter pin connectors with the appropriate plugs or protective caps.

NOTICE

Damage to the Sunny Multigate due to the use of cleaning agents

The use of cleaning agents may cause damage to components of the Sunny Multigate. If the Sunny Multigate is dirty or dusty, you can clean the enclosure, the ventilation slots, the type label, and the LEDs with a dry brush.

  1. Disconnect the Sunny Multigate from all voltage sources ( > Disconnecting the Sunny Multigate from Voltage Sources).
  2. Only clean the Sunny Multigate with a dry brush.

NOTICE

Damage to the inverter due to the use of cleaning agents

  1. If the inverter is dirty, clean the enclosure, the enclosure lid and the type label only using clear water and a cloth.
