Connecting the Power Supply Unit
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 (9 VDC to 36 VDC). 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).
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.
