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 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 seals on the enclosure lids in subfreezing conditions
If you open the enclosure lids when temperatures are below freezing, the enclosure seals can be
damaged. This can lead to moisture entering the inverter.
• Only open the enclosure lids if the ambient temperature is not below -5°C
• If a layer of ice has formed on the seal of the lid when temperatures are below freezing,
remove it prior to opening the enclosure lids (e.g. by melting the ice with warm air). Observe
the applicable safety regulations.
Damage to the inverter or product due to electrostatic discharge
Touching electronic components can cause damage to or destroy the inverter or the product
through electrostatic discharge.
• Ground yourself before touching any component.

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.

Installation ManualMDSEN-40-IA-en-1012

2. To achieve an optimum WLAN range, the module should ideally be installed on module slot
M1. Perform the following steps:
• Guide the three guide pins on the
communication assembly through the holes
in the module. The holes in which the guide
pins must be inserted depend on the
module slot.
• Carefully push the module down on the
upper edge and on the connection sockets
at the same time ( ) until it audibly snaps
into both side locking tabs of the
communication assembly ( ). The
connector strip on the back of the module is
automatically pushed into the socket
terminal strip of the communication
assembly.
3. Tighten the fastening screw with a Torx
screwdriver (TX 25) on the module (torque:
1.5Nm). This additionally fixes the module in
place and grounds it in the inverter enclosure.
