2.3.2 Load Cells
To attach cable from a load cell or junction box, remove connector J1 from the board. The connector plugs into a
header on the board. Connect cable from the load cell or junction box through the load cell cable cord grip to
connector J1 as shown in Table 2-1. If using 6-wire load cell cable (with sense wires), remove jumpers JP1 and JP2
before reinstalling connector J1 (see Figure ). For 4-wire installation, leave jumpers JP1 and JP2 on.
When connections are complete, reinstall connector J1 on the board.
SHIELD wire connection is not used. Use grounding procedure described in Section 2.3.1.
For 6-wire connections, remove jumpers JP1 and JP2.
