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
2
cable, etc.
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 forming the unit, all the line and DC link connections must be
disconnected.
♦
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 depends on the
idle time of the converter.
