Installation of Dehumidification Device for Miniature Electrical Enclosures

Installation of Dehumidification Device for Miniature Electrical Enclosures

1. Installation Methods: Based on the principles of field usability and maintenance convenience, the unit can be installed using either DIN-rail mounting or bracket hanging via the support mounting hardware. Secure the unit with M4 screws, ensuring it remains perfectly horizontal without any tilting.

2. Clearance Requirements: Maintain a clearance of greater than 10 cm between all sides of the device and surrounding objects to ensure unobstructed airflow from the fan vents.

3. Drainage Tube Setup: Connect one end of the water drainage tube to the outlet port of the device and secure it with a hose clamp. Keep the tube straight and untangled along its path to facilitate smooth drainage, and lead the other end outside the cabinet.

How Dehumidification Works

  1. When the humidity sensor detects that humidity has reached the upper set limit, the dehumidifier starts dehumidifying. When humidity falls to the set cut-off value, it stops. This cycle repeats to keep humidity under control.
  2. The dehumidifier measures the current ambient temperature and humidity, and its software calculates the dew point of the environment. When the dew point is reached, it starts dehumidifying and switches on the heating contact at the same time. Once the dew point condition is broken, heating stops while dehumidification continues, and the unit stops after a set delay.

Note: Models without “T” in the model number do not have dew-point detection.

Special Functions

1. Automatic defrost:
All series have an automatic defrost function. When frost forms on the condensing plate, the dehumidifier defrosts automatically before resuming dehumidification.

2. Low-temperature heating (optional, selected according to site conditions):
When the dehumidifier detects that the ambient temperature is low, it automatically switches on an external heater for temperature compensation.
