Rockwell Automation SA3000 High Power Modules - Manual (Page 19)

Mechanical/Electrical Description 2-7
Each SA3000 Inverter Power Module connected to an SB3000 Power Module
supplied DC bus must have a separate pre-charge resistor and contactor to limit the
current into its capacitor bank. It is the responsibility of the application tasks to make
sure that the SB3000 Power Module is in run before the SA3000 Inverter Power
Module is put into run.
If the SB3000 Power Module is not in run, the DC bus voltage will not be high enough
to support the full rating of the SA3000 Inverter Power Module. If the SB3000 Power
Module is shut down due to a fault condition, controlled shutdown of the SA3000
Power Module is the responsibility of the application program running in the SA3000
UDC module.
!
ATTENTION: When used with an SB3000 Power Module, the SB3000
Power Module must be in run before the SA3000 Inverter Power Module
is put into run. If the pre-charge contactor supplying the SB3000 Power
Module is not closed, running the SA3000 Power Module will damage
the SB3000 pre-charge resistors. Failure to observe this precaution could
result in damage to, or destruction of, the equipment.
