Safety in installation and
maintenance
Precautions before electrical work
These precautions are for all personnel who do work on the inverter, its input and output
cables, the transformer or photovoltaic generator.
WARNING!
Obey these instructions. If you ignore them, injury or death, or
damage to the equipment can occur. If you are not a qualified electrician, do not
do installation or maintenance work. Go through these steps before you begin
any installation or maintenance work.
1. Clearly identify the work location.
2. Disconnect all possible voltage sources.
• Open the AC main switch-disconnector (Q1) and the DC main switch (Q2) of the
inverter.
• Open the disconnector of the transformer as the AC main switch-disconnector
(Q1) does not remove the voltage from the AC busbars of the inverter.
• Open the DC circuit breakers of the solar array junction boxes.
• Make sure that reconnection is not possible. Lock the disconnectors to open
position and attach a warning notice to them.
• After you have disconnected the inverter, always wait for 5 minutes to let the
intermediate circuit capacitors discharge before you continue.
3. Protect any other energized parts in the work location against contact.
4. Take special precautions when close to bare conductors.
5. Measure that the installation is de-energized.
• Use a multimeter with an impedance of at least 1 Mohm.
• Make sure that the voltage between the inverter AC output terminals (L1, L2, L3)
and the grounding (PE) busbar is close to 0 V.
• Make sure that the voltage between the inverter module UDC+ and UDC-
terminals and the grounding (PE) busbar is close to 0 V.
• Make sure that the voltage between the DC input terminals L+ and L- and the
grounding (PE) busbar is close to 0 V.
