To ensure your Siemens CAB-COVER for Backboxes is correctly installed and effectively protecting your CAB enclosure's ventilation holes, follow these steps: First, take the CAB-COVER and position it over the top of the CAB enclosure. Align the two studs on the CAB-COVER with the two slots that are nearest the front of the CAB opening. Now, secure the CAB-COVER by fastening the two nuts provided. Finally, verify that the open side of the CAB-COVER faces the back of the enclosure. If the open side is facing the back, your Siemens CAB-COVER for Backboxes is correctly installed.
