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
NOTE:
X Remember to replace the perspex safety panels over rectifiers V1 and V7 when the
measurements are complete.
DANGER: RISK OF DEATH BY ELECTRIC SHOCK
X Switch the placement system off at the main switch.
X Disconnect the placement system from the power supply.
X Wait approximately 1 minute until the residual voltages have dropped to a safe level
(electrolytic capacitor C1).
X Attach the perspex safety panel and fix in place with the M5 fillister head screws.
CAUTION Do not overtighten the fillister head screws. The perspex panel might break.

4.1.2.3 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.
