3 Inverter Manager
3.3.5 Connecting the
Inverter Manager to the Voltage
Supply
Danger to life due to electric shock from touching
an ungrounded product
Touching an ungrounded product can cause a lethal
electric shock.
• Ensure that the product is integrated into the existing
overvoltage protection.
• Ground the enclosure of the product.
Procedure:
To connect the Inverter Manager to the voltage supply,
perform the following actions in the specified order.
• Connect the grounding conductor to the
Inverter Manager.
• Connect the power supply unit.
Connecting the Grounding Conductor to the
Inverter Manager
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
the correct cable route help limit possible interference
emissions due to electromagnetic interferences (EMI).
Connecting the Power Supply Unit
GND
9 to 36 VDC
SMA recommends using the top-hat rail power supply
available as an accessory
(order number: CLCON-PWRSUPPLY).

SMA Solar Technology AG / SMA Solar Technology America LLC
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 connecting
terminal plate for the voltage supply (9 VDC to
36 VDC). Make sure that the shielded grounding
conductor is connected with the grounding terminal.
4. Plug the connecting terminal plate 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.
It is also possible to manually assign an IP address to the
LAN 1 port of the Inverter Manager with firmware version
1.60.
LAN 2 (inverter network)
The IP address is assigned to the inverter by the Inverter
Manager.
