Measuring voltages at rectifiers V1 to V8
The diagram above shows the position of rectifiers V1 to V7.
To measure the rectifiers V1 and V7, first remove the perspex panel.
1 T1 transformer 11.1 kVA 6 A 3 power fail board
2 V1 rectifier 7 Terminal strip X1
3 V2-V7 rectifier S101-B6U 160-08 8 Connector strip X2 to X10, X12, X13
4 Z1 line filter - input voltage 9 Secondary terminal strip with fuses (output
voltage T1)
5 A2 current supply (5V/6.3A) 10 Electrolytic capacitor C1
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
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.
