When installing temperature sensors, bind the cables behind the sensors to the cable bridge,
keeping them 20 mm away from the sensor probes.
Temperature sensors must not be in touch with metal parts or cabinets.
Keep the temperature sensors facing the inside of the cabinets to ensure accurate
measurement of cabinet interior temperatures.
The hydrogen detection system needs to be replaced.
A spare hydrogen detection system of the same model is available and functional.
