Usage:
Filter fans are used for cooling stationary, closed electric cabinets of protection class I.
Installation guidelines:
Installation is performed in accordance with the installation diagram in the sequence 1 to 4. The enclosure cut−out (1) is to be made in
accordance with the included template. The mounting frame (2) is to be fitted with self−adhesive sealing band. The protective film is to be
removed from the sealing band prior to installation. The fastening screws for the mounting frame are included in the delivery. The hood
blades (4) must point downward. The electrical connection is made by means of pressure clamps. When installing EMC filter fans, ensure
good metallic contact between the enclosure cut−out (1) and the contact spring band on the mounting frame (2).
Operating temperature range: −40 °C to 70 °C (−40 °F to 158°F).
Function:
The cooling function is ensured only in combination with an exit filter (optional with axial fan). Notice: A heavily soiled filter mat results in
reduction in cooling performance. In the standard version, the air direction is from the outside to the inside. By turning the axial fan, the air
direction is reversed.
Maintenance:
The degree of soiling of the filter mat must be monitored. Replace, blow out, or beat the filter mat as necessary. To do this, pull off the hood
(4), which is secured with snap clips.
