(Optional) Connecting the Water Sensor
Context
This section describes how to connect a water sensor. A water detection cable can also be connected.
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
- Connect one end of the water sensor cable to the water sensor.
- Connect the other end of the water sensor cable to the signal terminals 1 and 2 of X502 through the bottom of the cabinet.Figure 4-37 Connecting the water sensor
- Secure the cable to the post of the cabinet using cable ties.
Place the sheet metal of the water sensor upwards and its detection board downwards on the ground.
