2 Safety
2.1 Skills of Qualified Persons
The tasks described in this document must only be performed by qualified persons. Qualified
persons must have the following skills:
• Knowledge of how an inverter works and is operated
• Training in how to deal with the dangers and risks associated with installing and using
electrical devices and systems
• Training in the installation and commissioning of electrical devices and systems
• Knowledge of the applicable standards and directives
• Knowledge of and compliance with this document and all safety precautions
2.2 Safety Precautions
This section contains safety precautions 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 follow all safety precautions 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 by qualified persons with the
appropriate skills only.
• 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 Section3, page8).
Danger to life due to electric shock
Touching an ungrounded PV module or an 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.
2 Safety SMA Solar Technology AG
Service ManualSTP5-12TL-20-SG-en-126
Risk of burns due to hot enclosure parts
Some parts of the enclosure can get hot during operation.
• During operation, do not touch any parts other than the enclosure lid of the inverter.
Damage to the seal of the enclosure lid in sub-zero conditions
If you open the enclosure lid in sub-zero conditions, the sealing of the enclosure lid can be
damaged. This can lead to moisture entering the inverter.
• Do not open the inverter at ambient temperatures lower than -5°C.
• If a layer of ice has formed on the seal of the enclosure lid in sub-zero conditions, remove it
prior to opening the inverter (e.g. by melting the ice with warm air). Observe the applicable
safety regulations.
Damage to the inverter due to electrostatic discharge
Touching electronic components can cause damage to or destroy the inverter through
electrostatic discharge.
• Ground yourself before touching any component.
Damage to the display or the type label due to the use of cleaning agents
• If the inverter is dirty, clean the enclosure, the cooling fins, the enclosure lid, the type label,
the display and the LEDs using clean water and a cloth only.

3 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. It is important to always observe the prescribed sequence.
Destruction of the measuring device due to overvoltage
• Only use measuring devices with a DC input voltage range of 1,000V or higher.
1. Disconnect the circuit breaker from all three line conductors and secure against reconnection.
2. Remove the ESS.
3. Loosen two screws of the protective cover using an Allen key (AF5) and remove the protective
cover.
4. Use a current clamp to ensure that no current is present in the DC cables.
5. Release and remove all DC connectors. Insert a
flat-blade screwdriver or an angled screwdriver
(blade width: 3.5mm) in one of the side slots
and pull the DC connectors straight out. Do not
pull on the cable.
6.
Danger to life due to high voltages
The capacitors in the inverter take five minutes to discharge.
• Wait five minutes before opening the enclosure lid.
7. Ensure that no voltage is present at the DC inputs of the inverter.
8. Unscrew all the screws of the enclosure lid using an Allen key (AF5) and remove the
enclosure lid.
9. Use an appropriate measuring device to ensure that no voltage is present at the AC
connecting terminal plate between L1 and N, L2 and N, and L3 and N. Insert a test probe in
each round opening of the terminal.
10. Use an appropriate measuring device to ensure that no voltage is present at the AC
connecting terminal plate between L1 and PE, L2 and PE, and L3 and PE. Insert a test probe
in each round opening of the terminal.
11. 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.
