SMA America, LLC

SB3-5TLUS22-IA-en-10

Installation Manual

8.1 Disconnecting the DC Disconnect from Voltage Sources

1. Turn the rotary switch of the DC Disconnect to

Off

2. Wait until the LEDs and the display have gone out.
3. Undo two screws on the DC Disconnect and

remove the switch and lid of the DC Disconnect.

5. If a DC disconnecting switch is available, open the the DC disconnecting switch.
6. If there is no DC disconnecting switch available, cover the PV modules with opaque material or

disconnect the connectors on the PV modules.

7. Ensure that no voltage is present in the DC terminals.

Danger to life due to electric shock when touching the DC conductors and DC
terminals

High voltages are present in the DC cables and DC terminals.

• Before performing any tasks, wait five minutes until the residual voltage has been drained.
• Do not touch the DC conductors and DC terminals.
