Applying AC Power
Once AC Voltage Measurements are complete, apply AC power to the
Power Cabinet. Table 2-4 provides the procedure for applying AC
power.
Table 2-4: Applying AC Power
Step Action
1 When the input voltages are verified as correct, turn the Main AC breaker (located on the front of the
AC Load Center) ON. Observe that all eight (8) green LEDs on the front of the AC Load Center are
illuminated (see Figure 2-7).
2 Turn Rectifier 1 and Rectifier 2 AC branch breakers (on the AC Load Center) ON. All the installed
rectifier modules (see Figure 2-7) will start up and should each have two green LEDs (DC and Power)
illuminated.
3 Turn the Meter Alarm Panel module, ON (see Figure 2-3), while observing the K2 contact in the
PDA assembly (see Figure 2-9). The contact should close. The Meter Alarm Panel voltage meter
should read approximately 27.4 +
0.2 Vdc.
4 Turn the Temperature Compensation Panel (TCP) ON, (see Figure 2-4). Verify that the Meter Alarm
Control Panel does not have any alarm LEDs illuminated.
5 Check the rectifier current bargraph displays (green LED display on the rectifier module). None
should be illuminated at this point.
If batteries are fitted, turn on the two battery heater AC
breakers on the AC Load Center.
