● Each unit supports a maximum of twelve T/H sensors outside the unit, including a
maximum of six cold aisle T/H sensors and six hot aisle T/H sensors.
● It is recommended that the total length of the cable required for the T/H sensors
outside the unit be less than or equal to 150 m. If the cable length is greater than 120
m, obtain 12 V DC power from the site to supply power to the T/H sensors that are 120
m or further away from the cabinet. Ensure that the input voltage of each T/H sensor
ranges from 9 V to 16 V.
