SMA DATA MANAGER M - Connecting the Voltage Supply

6 Connection
SMA Solar Technology AG
Operating manualEDMM-10-BE-en-2734
Procedure:
1. Plug the RJ45 plug of the network cable into the network port X4 or X5 until the RJ45 plug
snaps into place. The assignment of the network cables to the ports is not relevant, as the ports
constitute a switch function.
2. Connect the other end of the network cable to the network.
6.6 Connecting the Voltage Supply
WARNING
Danger to life due to electric shock
Under fault conditions, when working on the power supply circuit there may be dangerous
voltages present on the product. This can result in death or serious injury.
• For power supply units with a fixed connection, make sure that a disconnection unit (e.g.
miniature circuit breaker) is present outside the power supply unit.
• For power supply units with a plug connection, make sure that the electrical outlet for the
power supply unit is close to the power supply unit.
• The disconnection unit and the electrical outlet for the power supply unit must be freely
accessible at all times.
NOTICE
Damage to the product due to condensation
If the product is moved from a cold environment to a warm environment, condensation may form
in the product. This can damage the product or impair its functionality.
• When there are large temperature differences, wait until the product has reached room
temperature to connect the voltage supply.
• Make sure the product is dry.
