1. Turn the POWER switch off.
2. Remove the sensing connector from the rear panel sensing terminals.
3. Remove the local sensing jumpers from the sensing connector.
4. Remove 7 mm of the wire covering. Connect the negative sensing cable to -S and the
positive sensing cable to +S.
Use cable screws to securely fix the cables in place so that they do not come loose.
5. Pinch the tip of the band, and remove the band from the connector cover.
6. As shown in the figure, create a ring 40 mm away from the connector, and fasten with the band.
Make the ring as small as possible, and fasten the band as tight as possible. The band can
be reused. Do not cut the extraneous portion of the band.
