Testing the System Prepower Checks
1. Using a meter, check that the line-to-line voltage readings are
within the tolerance given in Appendix A.
2. Check the line-to-line and line-to-ground (PE) resistance for each
unit. All readings should show a high resistance or open circuit.
Testing The System
Before testing the system, verify that all the circuit breakers are in the
off position and that the start switch on the parallel configuration is
turned to off. The bay doors should be closed.
1. Push each RGU circuit breaker lever to on (do not attempt to use
the NRU circuit breaker).
2. Turn the start switch to on. The RGU(s) will begin their
precharge operation. When the precharge sequence has finished
(about 15 seconds), the NRU circuit breaker will close.
You can check the programming terminal (HIM) for the bus
voltage and any fault information.
Note: The parameters for this unit may not have been configured
yet. If the unit will not operate, skip to chapter 16 to configure
the parameters.
3. Close the inverter circuit breakers and verify that the inverters are
receiving power.
4. Open all system circuit breakers.
