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.
• Do not touch non-insulated parts or cables.
• Disconnect the product from voltage sources and make sure it cannot be reconnected before working on the
device.
• Only disassemble the protective covers, if the product is disconnected from all voltage sources.
• Wear suitable personal protective equipment for all work on the product.
CAUTION
Risk of injury if the product tips over
The product is heavy and may tip over if not properly fastened to the support surface. This can result in crushing
injuries.
• Upon installation, attach the product to the support surface.
CAUTION
Risk of burns due to hot components
Some components and terminals inside the product can become hot during operation. Touching hot components or
terminals can result in burn injuries.
• Wear suitable personal protective equipment for all work on the product.
• Only operate the product with its protective cover mounted.
• Prior to removing the protective cover, let the product cool down.
CAUTION
Injury to persons or property damage due to unauthorized access to the grid and PV system
protection of the NA-Box
Unauthorized access or incorrect settings on the grid and PV system protection device in the NA-Box can cause grid
failures, yield losses, damage to the multicluster system or the NA-Box and injuries to persons. Furthermore, the
operating licence may also be revoked.
• Prior to commissioning the NA-Box, secure the grid and PV system protection device against unauthorized
access. The password protection must be activated on the grid and PV system protection device (see grid and
PV system protection documentation).
• Only operate the NA-Box when the grid and PV system protection device is secured against unauthorized
access.
