Chapter 2 Stand Alone Regulator Installation, Wiring and Configuration
Field Power Module Bridge
and Ground Wiring
The SAR contains a two quadrant field power module bridge. The field bridge
input circuit is rated for 100VAC…460VAC, ±10%, 50/60 Hz. The input and
output connections to/from the field bridge are on the bottom of the SAR as
shown.
An external transformer with appropriate primary fusing is required to supply the
field. External fusing is also required at the input terminals V1 and U1 to protect
the field bridge. The recommended fuse types are shown in the
Table 4 on
page 21 .
The SAR motor field current must configured with a hardware DIP switch and in
firmware. See
SAR Motor Field Current Configuration on page 26 for more
information.
