FIRST TIME OPERATION

This procedure is to be used to turn on a one Cabinet Power Source for the first
time, or when service has been performed. Proceed as follows:
FIRST TIME OPERATION
STEP 1: Verify the AUTO RE-START option has been disabled by switching S14-1 OFF
(refer to Section 4.5.2, Figure 4.5.2.)
STEP 2: Inspect the installation. Verify that the wiring is correct (refer to Section 3.0, figure
3.6, and figure 3.7.) If this is first time turn-up operation, complete Table 4.2,
(Installation Record) as operation proceeds.
STEP 3: Open main breakers of output distribution system. No load should be connected to
cabinet at this point.
STEP 4: Close input power circuit breaker. The OFF lamp on the Power Source Mode
Select switch should illuminate.
If this lamp does not light the EMER OFF lamp should be on. Press the DIAG then
f1 keys to determine the cause of the EMERGENCY OFF. If the EMERGENCY
OFF is caused by INPUT LINE FAULT, check the input power by pressing the
INPUT key on the front panel. ABNORMAL will be indicate if the input power is not
within limits and NORMAL if input power is within limits. Correct the fault, if any,
and proceed.
Rotate the Mode Select Switch to OFF and press START/RESET. The EMER OFF
indicator will go out.
STEP 5: Place the cabinet in the STANDBY state by rotating the Mode Select Switch to
STANDBY and pressing the START/RESET button. The STANDBY lamp will
illuminate. The high voltage power supplies are now energized and the inverters
are producing voltage. The output contactor is open. Cabinet output voltages and
frequency may be checked by pressing the OUTPUT then f1 keys on the front
panel.
STEP 6: If inverter voltage is not at desired levels, it may be changed by adjusting the
VOLTS ADJUST controls on the front panel. The center VOLTS ADJUST control
adjusts all three outputs simultaneously. ØB and ØC are trim adjustments.
Frequency may be changed by using the FREQUENCY SELECT switch. 50, 60,
and 400Hz are fixed crystal stabilized frequencies. The VAR position is variable
from 47 to 500Hz. The EXT position allows external oscillator input on connector
J6. The SLAVE position makes this cabinet a slave.
STEP 7: Place the cabinet in the ON State by rotating the Mode Select Switch to ON. The
internal output contactor is now closed, and the cabinet is ready to deliver load
power. Cabinet output voltages may be checked by pressing the OUTPUT then f2
keys on the front panel.
STEP 8: Close main breakers of the output distribution system. Monitor output voltages.
The output voltage should not change as load is applied.
