2 Safety

2.1 Safety Information

This section contains safety information that must be observed at all times when working on or with

the product.

To prevent personal injury and property damage and to ensure long-term operation of the product,

read this section carefully and observe all safety information at all times.

Danger to life due to high voltages of the PV array

When exposed to sunlight, the PV array generates dangerous DC voltage which is present in the

DC conductors and the live components of the inverter. Touching the DC conductors or the live

components can lead to lethal electric shocks. If you disconnect the DC connectors from the

inverter under load, an electric arc may occur leading to electric shock and burns.

• Do not touch uninsulated cable ends.

• Do not touch the DC conductors.

• Do not touch any live components of the inverter.

• Have the inverter mounted, installed and commissioned only by qualified persons with the

appropriate skills.

• If an error occurs, have it rectified by qualified persons only.

• Prior to performing any work on the inverter, disconnect it from all voltage sources as

described in this document (see Section2.2 "Disconnecting the Inverter from Voltage

Sources", page7).

Danger to life due to electric shock

Touching an ungrounded PV module or array frame can cause a fatal electric shock.

• Connect and ground the PV modules, array frame and electrically conductive surfaces so

that there is continuous conduction. Observe the applicable local regulations.

Risk of burns due to hot enclosure parts

Some parts of the enclosure can get hot during operation.

• Do not touch any parts other than the lower enclosure lid of the inverter during operation.

Damage to the display or the type label due to the use of cleaning agents

• If the inverter is dirty, clean the enclosure, the enclosure lid, the type label, the display and

the LEDs with a damp cloth only.

2 Safety SMA Solar Technology AG

Service ManualSB30-60TL-21-SG-en-116

2.2 Disconnecting the Inverter from Voltage Sources

Prior to performing any work on the inverter, always disconnect it from all voltage sources as

described in this section. Always adhere to the prescribed sequence.

Destruction of the measuring device due to overvoltage

• Only use measuring devices with a DC input voltage range of 1,000 V or higher.

Procedure:

1. Disconnect the circuit breaker and secure it against reconnection.

2. If an additional DC load-break switch is available, switch off the DC load-break switch and

secure against re-connection.

3. If an ESS is plugged in, remove the ESS.

4. If the multifunction relay is used, switch off any supply voltage to the load.

5. Wait until the LEDs, the display and if necessary, the load connected to the multi-function relay,

are switched off.

6. Use a current clamp to ensure that no current is present in the DC cables.

7. Remove all screws of the lower enclosure lid using an Allen key (AF3) and remove the

enclosure lid.

8. Release and remove all DC connectors. Insert a

slotted screwdriver or an angled screwdriver

(blade width 3.5mm) into one of the slide slots

and pull the DC connectors out downwards. Do

not pull on the cable.

9. Ensure that no voltage is present at the DC inputs of the inverter.

10. Use a suitable measuring device to check that no voltage is present at the AC connecting

terminal plate between L and N and L and PE. Insert the test probe (maximum diameter:

2mm) in each round opening of the terminal.

11. Flip the display up to have more space to make the measurement. Loosen the screw on the

display.

☑ The display clicks into place.

12. Ensure that no voltage is present between any terminal of the multifunction relay and PE of the

AC connecting terminal plate.

Damage to the inverter due to electrostatic discharge

The internal components of the inverter can be irreparably damaged by electrostatic

discharge.

• Ground yourself before touching any component.

3 Cleaning the Inverter

Damage to the display or the type label due to the use of cleaning agents

• If the inverter is dirty, clean the enclosure, the enclosure lid, the type label, the display and

the LEDs with a damp cloth only.

• If the cooling fins on the rear of the enclosure are dirty, clean them using a soft brush.

• If the air ducts on the top of the inverter are dirty, clean them using a soft brush.

4 Troubleshooting

4.1 LED Signals

The LEDs indicate the operating state of the inverter.

LED Status Explanation

Green LED glowing Feed-in operation

If an event occurs during feed-in operation, an event mes-

sage will be shown on the display (for event messages see

the service manual at www.SMA-Solar.com).

flashing The conditions for feed-in operation are not yet met. As

soon as the conditions are met, the inverter will start feed-

in operation.

Red LED glowing Error

If an error occurs, the error message and the correspond-

ing event number will be shown in the display. The error

must be rectified by a qualified person (for troubleshoot-

ing, see the service manual at www.SMA-Solar.com).

Blue LED glowing BLUETOOTH communication is activated.
