Load Cell Wiring
The load cell wiring from the IQ plus 310A has been connected to the intrinsic safety barriers at the factory, (see
Figure 2-4). The barriers are located in the bottom of the enclosure.
Wire the load cell cable from the load cell or junction to terminal block TB4 (shown below). If using six-wire
load cell cable (with sense wires), remove jumpers JP1 and JP2. For four-wire installation, leave jumpers JP1 and
JP2 on.
