Installing the Module
Maximum number of modules of the same device type per inverter
You can only use a maximum of one SMA Sensor Module per inverter.
Procedure:
1.
Danger to life due to high voltages of the PV array
When exposed to sunlight, the PV array generates dangerous DC voltage, which is present in
the DC conductors and the live components of the inverter. Touching the DC conductors or the
live components can lead to lethal electric shocks.
• Prior to performing any work on the inverter, always disconnect the inverter from voltage
sources on the AC and DC sides as described in the inverter manual. When doing so,
note that even if the DC load-break is switched off, there will be dangerous direct voltage
present in the DC conductors of the inverter.
