Input Terminals
Table 11 lists the input terminals on the drive. Text in parenthesis indicates the default setting for each multi-function
input.
Table 11 Control Circuit Input Terminals
Type
<1> Setting jumper S3 for an external power supply makes the wire jumper between terminals H1, H2, and HC ineffective. Remove the wire jumper
and connect an external power supply that can supply terminals H1, H2, and HC continuously.
