For multiple cabinet systems, refer to Figure 2-2 thru Figure 2-5 for connection details.
2.6. OUTPUT VOLTAGE RANGES
The 0-135 Volt output is standard. The following outputs are available with an optional
transformer:
0-156V, 0-270V, 0-312V, 0-400V
2.7. FUNCTION TEST
Refer to Figure 2-6 for the test setup.
Perform the following test sequence for 135 VAC output unit.*
1) Apply the AC line power and turn on the front panel circuit breaker. No
loads should be connected to the output terminal block.
2) Verify that the POWER ON lamp is lit.
3) With the front panel keypad program the output to 135 volts with the
following key sequences:
Depress the MON key 1 time to select the Amplitude screen (AMP)
( or press 5 ENT).
135 PRG ENT Program the voltage to 135 volts:
4) Verify that the front panel voltmeter indicates approximately 135 volts for all
three phases or for phase A for a 1-phase system.
5) Observe each of the outputs with the oscilloscope or distortion analyzer. The
outputs should be clean sine waves having less than 2.0% distortion.
*For 156V, 270V, 0-312V or 0-400V units replace 135V in the text with the relevant
voltage.
