4) At this point the electrical connection of the ERS to the frequency inverter has to be
completed. First of all,
accidental reconnection is not possible.
5) Follow the instructions of the frequency inverter installation manual and wait the
required lap of time until the DC bus voltage falls down to safe levels.
6) Follow the instructions of the frequency inverter installation manual and gain access to
the DC bus connectors P(+) and N(-).
7) Using a multimeter measure the residual voltage at connectors P(+), N(-).
8) If the remaining voltage is at safe levels (<50V) you can continue with the installation
process. If not, wait.
9) Check the switch of the ERS 2G (element nº 7 from description in section 2) is OFF.
10) Image below shows how this connection should be made. The naming of the terminals
