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.
