2 Safety
2.1 Intended Use
The SMA Power Control Module is a multifunction interface which enables grid management services
to be implemented for one inverter. In addition, the module is equipped with a multifunction relay.
The module is available as a retrofit kit or is pre-installed in the inverter.
The module must only be used with the supported products.
The inverter still complies with the standard after the product has been installed.
For safety reasons, it is not permitted to modify the product or install components that are not explicitly
recommended or distributed by SMA Solar Technology AG for this product.
The enclosed documentation is an integral part of this product.
• Read and observe the documentation.
• Keep the documentation in a convenient place for future reference.
2.2 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 to life due to electric shock when opening the inverter
High voltages are present in the live components of the inverter. Touching live components results
in death or serious injury.
• Prior to performing any work on the inverter, always disconnect the inverter from voltage
sources on the AC and DC sides (see inverter manual). Observe the waiting time to allow the
capacitors to discharge.
Risk of burns due to hot enclosure parts
Some parts of the inverter enclosure can get hot during operation. Touching these enclosure parts
can result in burn injuries.
• During operation, do not touch any parts other than the lower enclosure lid of the inverter.
Damage to the inverter due to electrostatic discharge
The internal components of the inverter can be irreparably damaged by electrostatic discharge.
• Ground yourself before touching any inverter component.
