Mounting the controller on a wall or flat
surface
To mount the A525 Fermentation Controller on a wall or
other flat surface, complete the following steps:
1. To open the controller cover, loosen the four spring-
loaded cover screws. Be careful not to damage the
controller’s interior components.
2. Attach an appropriate fastener onto the wall or other
flat surface.
3. Position the keyhole slot on the rear of the enclosure
base over the fastener. Make sure that the controller
hangs securely on the fastener.
4. Use the four holes on the corners of the enclosure
base to mark the location for the mounting screws.
Remove the keyhole slot fastener from the wall or flat
surface.
5. Use four screws to mount the controller: M4 (#8)
pan-head screw; 12 mm (0.5 in.) or longer.
6. Tighten the screws. Use shims to prevent warping the
enclosure.
7. To seal the cover, close the front cover and tighten
the spring-loaded cover screws to 0.9–1.1 N·m (8–10
in·lbs).
DIN rail mounting
You can optionally order a DIN rail mount kit (BKT524-1K)
for the A525 Fermentation Controller. Attach the DIN rail
clip assembly to the five holes on the rear of the enclosure
base.
Refer to the installation instructions included with the DIN
rail kit for DIN rail mounting procedures.
