Mounting position of the enclosure

Mounting hardware

Method 1: The HF4 is supplied with 2 screws, 2 drywall anchors and two
rubber washers. The base of the enclosure has 2 screw-wells (see drawing)
that are normally closed at the bottom. Use the template provided with the HF4
to drill mounting holes in the wall and insert the drywall anchors. Place a
rubber washer on each screw. Insert a screw in each well and push to open
the bottom of the well.

Method 2: When a DIN-rail

(35 mm / 1 3/8 “) is available use part AC5002 (not

included). This is a DIN-rail mounting kit consisting of 2 clamps that attach to
the back of the enclosure with the screws provided.
