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
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
V5 3 x 8.14 VAC 8 VDC
V6 3 x 40.7 VAC 48 VDC
V7 3 x 24.4 VAC 24 VDC
NOTICE
► Remember to replace the perspex safety panels over rectifiers V1 and V7 when the meas-
urements are complete.
DANGER
RISK OF DEATH BY ELECTRIC SHOCK
► Switch the placement system off at the main switch.
► Disconnect the placement system from the power supply.

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. This is used
to supply the PC and the monitor.
