3.12.5 Connecting the Water Sensor

Context
A water sensor monitors resistance changes at terminals to determine whether the floor is
watery. When the terminals of a water sensor detect water or other conductive liquid,
resistance between the two terminals decreases. Keep water sensors far away from water traps
or floor drains.
Procedure
Step 1 Connect one end of the water sensor cable to the water sensor.
Step 2 Connect the other end of the water sensor cable to Water– and Water+ on the water sensor at
the signal port through the signal cable hole at the top of the cabinet.
Step 3 Secure the cable to the left post of the cabinet using cable ties.
Place the sheet metal of the water sensor upwards and its detection board downwards on the
ground.

3.12.6 Connecting the T/H Sensor Outside the Cabinet

Context
T/H sensors outside the cabinet are configured to detect the temperatures of cold/hot aisles.
They can be flexibly installed on the server cabinet based on onsite situation. It is
recommended that the T/H sensors be deployed near heat sources in the hot aisle, or in places
which lacks cooling air in the cold aisle. The T/H sensors outside the cabinet must be near the
smart cooling product to sense the temperature of the outlet air, and must be away from the air
exhaust vents of other smart cooling products
Procedure
Step 1 Connect the T/H sensors outside the cabinet and the T/H sensors at the return air side in series.
