Figure 27. Test Voltage (Expansion Rack)
Record the measured voltage on the test results sheet.
2. Switching on the racks. (Test 1b)
DA Rack
Switch the CT Combiner Rack ON by placing both breakers up and wait for the system
to complete the power-up self test sequence successfully. The two breakers duplicate
power to each shelf and the shelves will still function if one power supply fails though
the LED indicators on the power supplies will not be on.
Using the DMM check that the DC voltage supply across the input terminals (1+ & 1-
for Supply 1 and 2 + & 2- for supply 2) is still within the specified limits and record on
the test results sheet.
Expansion Rack
Switch the CT Expansion Rack ON by placing both breakers up and wait for the system
to complete the power-up self test sequence successfully. The two breakers duplicate
power to each shelf and the shelves will still function if one power supply fails though
the LED indicators on the power supplies will not be on.
Using the DMM check that the DC voltage supply across the input terminals (TB1(-);
TB2+;.for Supply 1 and TB4(-); TB5(+) for supply 2). Ensure that the voltage
measured complies with the site nominal voltage and is within the limits specified on the
test results sheet.
