Safety during Maintenance


DANGER

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

High voltages are present in the conductive components or cables of the product. Touching live parts and cables results in death or lethal injuries due to electric shock.

  1. Do not touch non-insulated parts or cables.
  2. Disconnect the product from voltage sources and ensure it cannot be reconnected before working on the device.
  3. Wear suitable personal protective equipment for all work on the product.

DANGER

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

When exposed to light, the PV modules generate high DC voltage which is present in the DC cables. Touching live DC cables results in death or lethal injuries due to electric shock.

  1. Do not touch non-insulated parts or cables.
  2. Disconnect the product from voltage sources and ensure it cannot be reconnected before working on the device.
  3. Do not disconnect the DC connectors under load.
  4. Wear suitable personal protective equipment for all work on the product.

WARNING

Danger to life due to electric shock when touching live components or cables while the device is exposed to sunlight

In the event of a fault, a high voltage may be present at the DC terminals on the inverter. Touching live components can result in death or serious injury due to electric shock.

  1. Immediately disconnect the inverter from voltage sources and secure it against being switched on again.
  2. Stop all work on the inverter until nightfall.
  3. Wear suitable personal protective equipment of the corresponding hazard risk category for all work.

NOTICE

Damage to the inverter due to unapproved spare parts

If accessories and spare parts not approved by SMA Solar Technology AG are used for maintenance, the product may be damaged.

  1. Only use spare parts approved by SMA Solar Technology AG.
