Key specifications

How to use

Mount the heater inside the enclosure according to Rittal's mounting points and orientation recommendations to ensure proper airflow. Connect the unit to a 230 V supply using the quick-connect terminal and observe the maximum current rating of 6 A. Allow sufficient clearance around the fan inlet and outlet for unobstructed air circulation. Verify that the enclosure's ventilation and any associated thermostats or controllers are configured to work with the heater's output.

Recommendations

Install the heater in a location that prevents direct contact with wiring or sensitive components, and follow applicable safety and grounding practices. For condensation control, operate the heater continuously or with a temperature controller set to the desired minimum temperature. Refer to Rittal installation instructions for torque values and detailed wiring diagrams.
