4.5 SENSOR CONNECTIONS
When using the SymphoniePRO-26 wiring panel, it is recommended that
you first install the wiring panel in the shelter box and connect the
sensor wires before installing the SymphoniePRO and iPack. The wiring
panel is mounted to the shelter box by inserting the shelter box’s 4
lowest mounting screws through the holes in the wiring panel bracket,
sliding it to the left, and then tightening the screws to secure it.
Caution
Make sure that the wiring panel’s ground wire is connected to the
earth ground rod before connecting sensor wires! The earth ground
wire should be trimmed to the required length to reach the ground
rod, and excess wire should not be rolled up or coiled.
When using the SymphoniePRO-16
wiring panel, it will be easier to
connect the sensor wires to the
wiring panel before plugging the
wiring panel onto the logger.
