ESD guidelines

No guarantee or warranty claims can be made in respect of any improperly handled elec-
tronic component or PC board.
WARNING! An electric shock can be fatal. Before opening the device:
- If applicable, turn the mains switch to the O position
- Unplug the device from the mains
- Disconnect the inverter from the DC side
- Using a suitable measuring instrument, ensure that electrically charged parts
(e.g. capacitors) are fully discharged
- Restrict access to the working area
- Take steps to ensure the metallic surfaces of the device cannot be touched
- Suitable protective clothing and/or equipment must be worn when carrying
out the test or the repair
WARNING! An electric shock can be fatal. Danger due to residual voltage in ca-
pacitors. Wait for the capacitors to discharge. See the operating instructions and
the safety notices on the inverter for more details on the discharge time.
WARNING! Incorrect operation or poorly executed work can cause serious injury
or damage. Commissioning of the inverter may only be carried out by trained per-
sonnel in accordance with the technical regulations. The "Safety Rules" section
must be read prior to commissioning the equipment or carrying out servicing or
repair work.
WARNING! An electric shock can be fatal. Danger due to mains voltage and DC
voltage from solar modules.
- The connection area must only be opened by an authorised electrician.
- The separate area containing the power stage sets must only be disconnect-
ed from the connection area when in a de-energised state.
- The separate area containing the power stage sets must only be opened by
a Fronius-trained service technician.
- Make sure that both the AC side and the DC side of the inverter are de-ener-
gised before making any connections.
WARNING! An inadequate ground conductor connection can cause serious inju-
ry or damage. The housing screws provide a suitable ground conductor connec-
tion for earthing the housing and must NOT be replaced by any other screws that
do not provide a reliable ground conductor connection.
NOTE! Requirements concerning electrical installations may be subject to nation-
al standards and directives, which must be observed.
A safety inspection must be carried out after replacement, maintenance or repair
work on any component (see "Safety inspection").
NOTE! Observe ESD guidelines when handling electronic components and PC
boards. This primarily applies to ESD compatible
