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.
