5 Disassembling the Defective Power Unit
SMA Solar Technology AG
Service Manual SBSxx-10-AT-PU-SG-xx-10 9
5 Disassembling the Defective Power Unit
Prior to disassembling the defective Power Unit, all connections between the Power Unit and the
Connection Unit must be severed. Only then can the Power Unit be removed from the Connection
Unit. All cables connected to the communication assembly can remain plugged in and do not need
to be removed to disassemble the PowerUnit.
Procedure:
1. DANGER
Danger to life due to high voltages
• Disconnect the inverter from voltage sources (see inverter manual).
2. Remove the terminal block with the connected DC
conductors from slot DC-in. To do this, unscrew the
screws using a flat-blade screwdriver (blade width:
4mm (5⁄32in)) and pull the terminal block out of
the slot. While doing so, only touch the terminal
block on the black enclosure.
3. Remove the terminal block with the connected AC
conductors from slot AC-out. To do this, unscrew the
screws using a flat-blade screwdriver (blade width:
4mm (5⁄32in)) and pull the terminal block out of
the slot.
4. If there is a switch and an outlet for secure power
supply operation connected, remove the terminal
block with the connected cable from the SPS slot. To
do this, unscrew the screws using a flat-blade
screwdriver (blade width: 3.5mm) and pull the
terminal block out of the slot.

7. If the inverter is fitted with a padlock for theft
protection, open the padlock and remove it.
8. Using a Torx screwdriver (TX 25), unscrew the
screw M5x60 which fastens the inverter to the wall
mounting bracket.
9. Unscrew the two screws on the right and left side of
the PowerUnit with a Torx screwdriver (TX25) and
retain together with the washers for later use.

10. Lift to remove the Power Unit out of the wall
mounting bracket, thus separating the Power Unit
from the Connection Unit.
TOP
11. If necessary, remove residual insulation material
from the two connection openings at the top of the
Connection Unit.
6 Mounting the New Power Unit
1. DANGER
Danger to life due to high voltages
• Disconnect the inverter from voltage sources (see inverter manual).
2. Hook the new Power Unit into the upper recesses of the wall mounting bracket, thus plugging
the Power Unit into the Connection Unit. Make sure that the screw holes on the left and right
sides of the PowerUnit are directly over those of the ConnectionUnit; and the cables
protruding from the PowerUnit must not be pinched.
3. Fasten two screws with washers on the right and left side of the PowerUnit using a Torx
screwdriver (TX25) (torque: 6Nm ± 0.3Nm).
4. Secure the inverter to the wall mounting bracket. To
do this, insert the screw M5x60 through the hole on
the left side of the PowerUnit using a Torx
screwdriver (TX25) and screw it into the thread
(torque: 1.7Nm ± 0.3Nm).
5. If the inverter is to be protected against theft, attach a padlock:

9. DANGER
Danger to life due to electric arc
The terminal block must be fastened to the slot with two screws. If the terminal block is not
correctly mounted and comes out of the slot, an electric arc can form. An electric arc can
cause life-threatening injuries.
• Mount the terminal block on the slot as described in the following.

10. Tighten (torque: 1.7Nm ± 0.3Nm) the screws of
the terminal block using a flat-blade screwdriver
(blade width: 3.5mm).
11. Ensure that the terminal block is securely in place.
12. Plug the terminal block with the connected AC
conductors into the AC-out slot in the
ConnectionUnit, and tighten (torque: 1.7Nm ±
0.3Nm) with a flat-blade screwdriver (blade width:
3.5mm).
13. If applicable, plug the terminal block with the
connected cable for secure power supply operation
into the SPS slot in the Connection Unit, and tighten
(torque: 1.7Nm ± 0.3Nm) with a flat-blade
screwdriver (blade width: 3.5mm).
14. Commission the inverter (see inverter manual). The starting process of the inverter will take up
to 20 minutes since all relevant information is transferred from the ConnectionUnit to the
PowerUnit, and the PowerUnit may also be updated.
15. If the inverter firmware could not be updated prior to replacing the PowerUnit and the inverter
is not yet equipped with the current firmware version, perform a firmware update (see manual
of the inverter).
16. If a firmware update has been carried out, ensure that all parameters have been transferred
correctly and that the inverter feeds grid-compliant current into the utility grid.
