Installing the Module
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.
Damage to the product due to sand, dust and moisture ingress
Sand, dust and moisture penetration can damage the product and impair its functionality.
Maximum number of modules per inverter
You can only use a maximum of one module of the same device type per inverter.
Procedure:
1. Disconnect the inverter from voltage sources (at www.SMA-Solar.com).
2. Remove the enclosure lid of the DC Connection Unit. Unscrew all screws with a Torx screwdriver (TX25) and
remove the enclosure lid carefully forward.
