4.2.3 Terminal Detail
All electrical connections except power are made via removable terminals located on the top
and bottom of the controller. The power connection is made via the power connector attached
to the DIN rail.
For security we recommend the use of Key Switches for the remote reset and inhibit inputs
mounted on the front of the enclosure in which the Unipoint is mounted.
