Insert crank handle onto shunt shaft protruding through front panel and turn crank handle to adjust shunt to the proper vale of “X”, de- pending on model (see detail of transformer and shunt.

Remove crank handle.

5 Pinion Gear

Install pinion gear onto front panel making sure anti-rotation pins are in holes on front panel.

6 Pointer Gear

Install pointer gear overtop of pinion gear and rotate so pointer is indicat- ing 130 Amps on ac Low Range scale (see example).

Install crank handle overtop the sta- tor/pinion gear assembly with the handle straight down. It may be necessary to turn the handle slight- ly so vertical alignment is possible.

7 Securing Screw

Install securing screw through han- dle, into threaded hole in shunt shaft. Tighten securely.
