OVR Override Box
The OVR board is designed for 3” snap track mounting. It
can be mounted (1) inside of a Danfoss I/O enclosure, or
(2) in control panels where codes and good electrical
practice permit.
The OVR enclosure door is hinged on the left side. Install
the box so there is no interference with the door opening.
Each OVR connected to an AKC 55 must have a unique
address starting with 01. Each address switch has an
arrow pointer which is also a screwdriver slot for setting
the address.

connections between boards.
The last I/O board on each cable run must be terminated.
Terminations are supplied with the AKC 55 controller as

When necessary, individual I/O boards can be placed on
individual stubs up to a maximum of 25 feet long off a main
