(Optional) Connecting T/H Sensors Outside Cabinets
6.2
The T/H sensors outside the cabinet are used to detect the long-distance temperature and
humidity. They can be flexibly installed based on the onsite situation. It is recommended that
the sensors be deployed near heat sources, or near places that lack cooling air. Place the T/H
sensors outside the cabinet near the cabinet and do not directly face them to the air exhaust
vent of the equipment.
1. Connect the IN port on the first T/H sensor outside the cabinet to the RS485/12V port on the
main control board.
2. Connect the OUT port on the T/H sensor outside the cabinet to the IN port on the next T/H
sensor outside the cabinet in series.
3. Set the DIP switches on the T/H sensors.
