2 Safety Information SMA Solar Technology AG
Service ManualSBSxx-10-AT-PU-SG-xx-106
DANGER
Danger to life from electric shock due to live DC cables at the battery.
The DC cables connected to a battery may be live. Touching the DC conductors or the live
components leads to lethal electric shocks.
• Do not touch non-insulated cable ends.
• Do not touch any live components.
• Have the inverter and the battery mounted, installed and commissioned only by qualified
persons with the appropriate skills.
• Observe all safety information of the battery manufacturer.
• Prior to performing any work on the inverter or the battery, disconnect the inverter from all
voltage sources as described in this document.
• Wait five minutes before working on the inverter.
• If an error occurs, have it rectified by qualified persons only.
WARNING
Risk of burns due to electric arcs
Short-circuit currents in the battery can cause heat build-up and electric arcs.
• Disconnect the battery from all voltages sources prior to performing any work on the
battery.
• Observe safety information of the battery manufacturer when working on the battery or
inverter.
CAUTION
Risk of burns from hot surfaces
The surface of the inverter can get very hot. Touching the surface can result in burns.
• Mount the inverter in such a way that it cannot be touched inadvertently.
• Do not touch hot surfaces.
• Wait 30 minutes for the surface to cool sufficiently.
• Observe the safety messages on the inverter.

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 PowerUnit.
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:
4mm (5⁄32in)) 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:
4mm (5⁄32in)) 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: 3.5mm) and pull the
terminal block out of the slot.
