Applying AC Power
Once the external AC power connections are verified, AC power may be
applied internally to the frame. Table 2-5 provides the procedure for
applying internal AC power.
Table 2-5: Applying Internal AC Power
Step Action
1 Be sure the requirements of Table 2-4 for AC input power connection verification have been met.
2 Be sure all DC PDA circuit breakers are set to OFF (pulled out), all ACLC front–panel circuit
breakers are OFF (down), and all battery shelf circuit breakers are OFF (pulled out).
3 Be sure the MAP power switch, TCP switch, and BATT TEST switch are all set to OFF.
4 If it has not already been done, set the facility circuit breaker supplying AC power to the frame
to ON.
5 Set the ACLC MAIN circuit breaker ON.
– For the North American cabinet:
Observe that all eight (8) green LEDs on the front of the ACLC are illuminated (NO TAG).
– For the International cabinet:
Observe that all four (4) green LEDs on the front of the ACLC are illuminated (NO TAG).
6 On the ACLC, set RECT. 1/3 and then RECT. 2/4 branch circuit breakers ON. All the installed
rectifier modules (NO TAG) will start up, and the green DC and PWR LEDs should light on each.
7
Set the MAP power switch to ON. The MAP VOLT display should read 27.4 + 0.2 VDC with the
TCP switch OFF.
! CAUTION
Once power is applied to the MAP, be careful not to short either of the VOLT TEST POINTS to
ground. Failure to comply will result in severe damage to the MAP.
8
On the MAP, set the TCP switch (Figure 2-5) to ON. Verify no alarm LEDs are lighted on the MAP.
NOTE
Depending on battery compartment temperature, the rectifier voltage displayed on the MAP VOLT
indicator may change by as much as +
1.5 V when the TCP is set to on.
9 Check the rectifier current bar graph displays (green LED display on the rectifier module). None
should be lighted at this time.
10
If batteries are fitted, set the ACLC HEATER circuit breaker to ON.
NOTE
The GFCI AC circuit breaker should remain OFF unless the GFCI outlet is in use.
