Damage to electronic components due to electrostatic discharge
Electrostatic discharge can damage or destroy electronic components.
• Observe the ESD safety regulations when working on the product.
• Wear suitable personal protective equipment for all work on the product.
• Discharge electrostatic charge by touching grounded elements. Only then is it safe to touch electronic
components.
Product can cause radio interference in living areas
The product is a device of ITE class A (EN 55022) and can cause radio interference in living areas.
• Take suitable measures for shielding radio waves when the Cluster Controller is used in the vicinity of living
areas.
Manipulation of system data in networks
You can connect the supported SMA products to the Internet. When connected to the Internet, there is a risk that
unauthorized users can access and manipulate the data of your system.
• Set up a firewall.
• Close unnecessary network ports.
• If absolutely necessary, only enable remote access via a virtual private network (VPN).
• Do not use the port forwarding feature. This also applies to the used Modbus ports.
• Disconnect system components from other network components (network segmentation).
Damage to the product due to cleaning agents
The use of cleaning agents may cause damage to the product and its components.
Damage of gensets due to overload of the system network
The system network can be overloaded due to direct communication with individual system components. As a result,
control commands from the product can no longer be sent correctly to the system components. This may lead to
reverse currents and damage to the gensets.
• Only operate the system network as documented in the acceptance test during commissioning.
• Only retrieve system data from individual system components via the product.
• Do not communicate directly with the individual system components.
