3.14.5 (Optional) Installing a T/H Sensor

Installing a T/H sensor outside the cabinet involves two operations: connecting the T/H sensor
cables and setting the DIP switch on the T/H sensor.
Context
If one smart cooling product controls multiple T/H sensors, set the DIP switches on the
sensors to specify their communications addresses that uniquely identify these sensors.
Figure 3-45 DIP switches on a T/H sensor
Procedure
Step 1 Route the sensor signal cables out of a hole on top of the cabinet. Connect the RS485_OUT
port of the upstream sensor to the RS485_IN port of the downstream sensor to connect them
in series.

Figure 3-46 shows the cable routing outside the cabinet.
The T/H sensor should be secured on the column of the cabinet in a smart module scenario, as shown in
Figure 3-46. In other scenarios, if drilling holes is allowed onsite, drill two M4 screw holes with an
interval of 88 mm. If drilling holes is forbidden onsite, bind the sensor to the door or column.
