DANGER
RISK OF DEATH BY ELECTRIC SHOCK
► Switch the placement system off at the main switch.
► Disconnect the placement system from the power supply.
NOTICE
The placement system must have started, otherwise there will be no AC voltage (3 x 140 VAC)
at rectifier V1.

Measuring voltages at main power filter Z1 and electrolytic capacitor C1
The diagram above shows the position of the power supply filter and the electrolytic capacitor C1.
▪ 4 main power filters for 36 A 3-phase systems
▪ 10 electrolytic capacitors 33000 µF / 63 V
Measuring voltages at transformer T1
Primary side of transformer T1
The transformer can be connected to the following main power supplies:
3 x 230 VAC for the "on-board electrical system" is drawn at terminals 1U5, 1V5 and 1W5. These are
used to supply the PC and the monitor.
Rectifiers Input Output
V1 3 x 140 VAC 200 VDC
V2 150 VDC 150 VDC
V3 3 x 32.5 VAC 40 VDC
V4 3 x 32.5 VAC 40 VDC
V6 3 x 40.7 VAC 48 VDC
V7 3 x 24.4 VAC 24 VDC
NOTICE
► Remember to replace the perspex safety panel over rectifier V1, when the measurements
have been completed.
DANGER
RISK OF DEATH BY ELECTRIC SHOCK
► Switch the placement system off at the main switch.
► Disconnect the placement system from the power supply.
