GE Healthcare Senographe DS
Revision 1 Service Information and Procedures Class A 2385072-16-8EN
Job Card PHY A016 - AC Connection
6-1 AC Supply Check
Determine the nominal voltage and frequency of the available power supply.
6-1-1 Check the Nominal Line Voltage
Consult the hospital electrician to determine the nominal line voltage and frequency. Then use the multi-
meter to measure the open-circuit line voltage to check that it corresponds to the nominal line voltage,
±10%. Allowable nominal line voltages are 200 V, 208 V, 220 V, and 240 V.
6-1-2 Line Frequency
The Senographe operates with line frequencies of 50 Hz or 60 Hz without adjustment.
6-2 Voltage Selection - Mains Distribution Rack
Check the position of the input connection wire on the Mains Distribution Rack transformer terminal
block (reference A in the illustration).
If the tap connection does not correspond to the nominal (not the measured) line voltage you determined
in section 6-1, remove and reconnect the W2 TRANSFOR LINE 1 cable to the correct terminal (200 V,
208 V, 220 V, 230 V, or 240 V). Do not change the position of W1 MAINS LINE 2/N cable, as it must
always be on the 0 V terminal.
