C. Wiring for PG Feedback Use
The MA7200 inverter has a built-in PG interface, no external PG feedback option
card is needed. An independent DC source of +12V should be provided from an
external source.

for more details on PG feedback.
4.
The A(+), A(-), IP12, IG12 terminals are integrated as CN2 in compact
version. (see page
1-9~1-10
). The code No. of the wire is 4H339D0250001.
5.
The PG interface only allows the open-collector interface drive or
complementary interface drive.
6.
The short pin of TP1 set to PULL UP position for open-collector interface
(factory setting) and set to OPEN position for complementary interface. The
PG interface only allows the open-collector interface drive or complementary
interface drive.
7.
The shielded twisted-pair cable wire should be used between the inverter and
PG, its length should be less than 150 feet.
