* For the single phase drives, the AC input line can
be connected to any two of the three input terminals R,S,T
* Three phase input power may apply to single phase drives.
Recommended Circuit when
power supply is turned OFF
by a fault output.
The contact will be ON
when the fault occurs to
turn off the power and
protect the power system.
