The unit has hazardous voltage levels up to 5 minutes after it has been
powered down due to the DC link capacitors. The unit or the DC link
terminals must not be worked on until at least after this delay time.
♦ Before you form the DC link capacitors, all DC link connections must
be disconnected.
♦ The converter incoming power supply must be switched off.
♦ The unit is not permitted to receive a switch-on command (e.g. via
the keyboard of the PMU or the terminal strip).
♦ Connect the required components in accordance with the circuit
example.
♦ Energize the forming circuit. The duration of forming is approx. 1
hour.
