If remote voltage adjust is not used, short terminals 6 and 7 together.
Short terminals 50 and COM together for 50 Hz operation. Leave unconnected for 60 Hz
operation.
The secondary winding of a sensing transformer must be grounded as closely to the
transformer as practical. When interconnecting more than one transformer, ensure that
the secondary winding of only one transformer is grounded.

NOTES
1. When more than three generators are to be paralleled,
continue connections as shown.
2. Paralleling CT polarities are shown with ABC phase rotation.
When connected in cross-current, external resistors may be
required to improve reactive load sharing among generators using
regulators with dissimilar current input burdens. Use the following
table as a guide.
