Observe the following safety notes when performing the work described in Section
Installation
.
DANGER!
Risk of death by electrocution!
– Only technical professionals may perform the work described in Section
Installation
.
– Always disconnect all DC and AC cables as follows before starting work on the inverter:
1. Turn the AC circuit breaker to off. Take measures to prevent the system from being unin-
tentionally switched on again.
2. Set the DC circuit breaker on the inverter to position 0. Take measures to prevent the
system from being unintentionally switched on again.
3. Disconnect the DC cable plug connectors (SunClix or Multi-Contact MC4) according to the
manufacturer's instructions; see Appendix. A special tool is required for the Multi-Contact
MC4.
Warning
DC cables carry voltage when the solar modules are subjected to sunlight.
4. Pull out the AC plug from the inverter as described in the Appendix under Mounting ⇒ AC
plugs.
5. Check that all pins of the AC plug are free of voltage. Use a suitable voltmeter for this (do
not use a simple neon phase checker).
– Do not connect cables to the inverter until explicitly asked to do so in the instructions.
– Do not open the casing of the inverter.
– Connect only SELV circuits to the RJ45 sockets.
– Lay the cables such that the connection cannot come loose accidentally.
– When laying cables, ensure that no damage occurs to any of the constructional fire safety
measures in the building.
– Make sure that no inflammable gases are present.
– Observe all applicable installation regulations and standards, national laws and connection
values specified by the regional power supply company.
