WARNING
Ignition source in a potentially flammable atmosphere! Fire hazard! Any
work on the energized terminals in the compressor terminal box could create
an ignition. Do not touch the energized terminals with a tool or cable when the
compressor is energized
WARNING
High voltage! Electrical shock hazard! Serious personal injuries!
Disconnect and lock out power before servicing. Allow drive components to
electrically discharge before servicing, respecting the time delay specified in
the drive manual. Use compressor with grounded system only. Refer to
original equipment wiring diagrams. Electrical connections must be made by
qualified electrical personnel.
Earth leakage current! Danger of electric shock! The combination of
compressor and drive can cause both AC and DC earth leakage current. To
protect against both kinds of leakage current it is recommended to use an
AC/DC sensitive RCD on the power supply side.
The combination of YHV*2P compressors and inverters can cause earth leakage currents, both AC
and DC, due to the presence of the inverter and an EMC filter in the system. Therefore, an AC/DC-
sensitive Residual Current Device (RCD) should be used on the power supply side. The RCD can
be either type B or B+.
NOTE: A K2 contactor is optional.
NOTE: For recommendations about electromagnetic compatibility and how to wire up the
drive assembly please refer to the ED3 User Manual (June 2019 version).
