Fig. 10-1 Forming circuit
♦ 1 fuse-switch triple 400 V / 10 A
♦ 3 incandescent lamps 230 V / 100 W
♦ Various small parts e.g. lamp holders, 1.5 mm
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 the unit or the front and
middle bar of the DC link bus module have to be removed (C/L+ and
D/L-).
♦ When the unit has been removed, connect PE2 to earth. Installed
units are earthed through the bar connection PE3.
♦ The unit is not permitted to receive a switch-on command (e.g. via
the keyboard of the PMU or the terminal strip).
♦ The incandescent lamps must burn darker / extinguish during the
course of forming. If the lamps continue to burn, this indicates a fault
in the unit or in the wiring.
♦ Connect the required components in accordance with the circuit
example.
♦ Energize the forming circuit. The duration of forming is approx.
1 hour.
