2.6.2 Installation Instructions.
The EPP III can be operated directly with the ECS/RS loads, or looped through the commercial
power converter (figure 2-12).
2.6.2.1 Direct operation with loads (normal operation).
The following two cases are possible:
Case 1:
ECS load only connected.
Case 2:
ECS and RS loads connected.
In either case, it is possible to switch without interruption between the two EPP III Generator Sets
150 kW, or to operate both generator sets 150 kW in parallel.
2.6.2.2 Operation with commercial power converter.
In this operating mode, the commercial power converter can be used as a third generator
(converter).
Five cases can occur when operating with the converter:
Case 1:
EPP III connected via converter; EPP III providing power to loads; changeover to
generator 1 or 2.
Case 2:
EPP III connected via converter; converter providing power to loads; changeover to
generator 1.
Case 3:
EPP III connected via converter; EPP III providing power to loads; converter shut down.
Case 4:
EPP III connected via converter; converter providing power to loads; EPP III shut down.
Case 6:
Converter providing power to loads; EPP III not connected.
In each mode, grounding must be provided between the units for voltage compensation and
lightning protection (figure 2-13).
