Connecting the Grounding Conductor to the
Inverter Manager
Figure 6: Position of the grounding screw
Shielded ground: The shielded ground (also called
"protected ground") is located at the pin connector for the
electrical connection in the displayed view.
Procedure:
• Ground the Inverter Manager. For this purpose,
connect the grounding conductor to the grounding
screw of the Inverter Manager. Proper grounding and
correct cable routing help limit the product's emitted
interference and susceptibility to interference. This
increases the quality of communication.

Connecting the Power Supply Unit

Figure 7: Pin assignment of the pin connector "Power Input"
SMA recommends using the top-hat rail power supply
available as an accessory (order number:
CLCON-PWRSUPPLY)* .
Procedure:
1. Mount the power supply unit (see the manufacturer
manual).
2. Connect the connection cable to the power supply unit
(see the manufacturer manual). Trim the unused
insulated conductors up to the cable sheath and write
down the conductor colors.
3. Connect the connection cable to the terminal block for
the voltage supply (DC input voltage 9 V to 36 V).
Make sure that the shielded grounding conductor is
connected with the grounding terminal.
* Not available in all countries.

4. Plug the terminal block for the voltage supply with
connected power supply unit in the pin connector
"Power Input" of the Inverter Manager.
5. Connect the AC connection cable to the power supply
unit (see the manufacturer manual).
6.
Danger to life due to electric shock
Lethal voltages are present at the connection
point of the utility grid.
• Disconnect the connection point from
voltage sources and make sure it cannot
be reconnected.
7. Connect the other end of the AC connection cable to
the voltage supply.
8. Connect the connection point to the utility grid.
☑ Once the Power LED is glowing green, the
Inverter Manager is ready for operation.
3.4 Ethernet Connection of the
Inverter Manager
LAN 1 (system network)
The IP address and the subnet mask are assigned to the
LAN 1 port of the Inverter Manager by an external DHCP
server.
An IP address can be manually assigned to LAN 1 Port of
the Inverter Manager.
Resetting the Inverter Manager to DHCP
• Press the power button three times in succession within
one second to reset the Inverter Manager to DHCP.
LAN 2 (inverter network)
The IP address is assigned to the inverter by the Inverter
Manager.
