6. If the multi-function relay or the SMA Power Control Module are used, remove the connection
cable from the inverter.
7. If other cables (e.g. data cables or network cables) are connected, remove them from the
inverter.
8. Remove any installed interfaces from the inverter (see the manual for the communication
interface).
9. Remove all conduits with cables from the inverter.
10. Close all enclosure openings.
11. Keep the DC load-break switch in a safe place as the replacement device will be delivered
without the DC load-break switch.
12.
Risk of burns due to hot enclosure parts
• Wait 30 minutes before disassembling the inverter. This will allow the enclosure to cool
down and thus prevent burn injuries.
13. Remove the inverter by lifting it vertically up and off the wall mounting bracket.
Commissioning the Replacement Device
Damage to seals on the enclosure lids in subfreezing conditions
If you open the upper and lower enclosure lids when temperatures are below freezing, the
enclosure seals can be damaged. This can lead to moisture entering the inverter.
• Do not open the inverter at ambient temperatures lower than -5°C (23°F).
• If a layer of ice has formed on the seal of the lid when temperatures are below freezing,
remove it prior to opening the enclosure lids of the inverter (e.g. by melting the ice with
warm air). Observe the applicable safety regulations.
Damage to the inverter due to moisture and dust intrusion
Dust or moisture intrusion can damage the inverter and impair its functionality.
• Close all enclosure openings of the inverter tightly.
• Never open the inverter when it is raining or snowing, or the humidity is over 95%.
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.
1. Mount the replacement device (see Section 5, page 18) and make the electrical connections
(see Section 6, page 24).
2. If needed, install interfaces in the replacement device and connect the interfaces (see the
interface manual).
