Connecting the Grounding Conductor to
the Inverter Manager
igure 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. or 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
igure 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.
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.
