Connecting Your 1394 SERCOS Interface System 3-3
Input Power Conditioning
In most applications, you can connect the 1394 system module
directly 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.
