Input Power Conditioning
You can directly connect the 1394 to a three-phase, AC power line.
However, if certain power line conditions exist, the input power
component can malfunction. If either of the following is true, you can
use a line reactor or isolation-type transformer to reduce the
possibility of this type of malfunction:
The AC line supplying the drive has power factor correction
capacitors.
The AC line frequently experiences transient power interruptions
or significant voltage spikes.
Important: Line conditioning is not typically required. If you have
experienced power problems in the past on a power
distribution line, you may need to consider input power
conditioning.
!
ATTENTION: The 1394 does not supply line fuses
or a circuit breaker. They are customer-supplied items.
Branch circuit breakers or disconnect switches cannot
provide the level of protection required by drive
components. Refer to Appendix A for size and type
recommendations.
