DS7400Xi Reference Guide Addendum
For DS7400Xi Underwriters Laboratories of Canada (U.L.C.) Commercial Fire Applications, the following
two modifications are required:
1. Do not use the enclosed transformer, instead use a CSA approved Class 2 transformer that is
approved for fire monitoring station applications, such as the Basler S19591-0028.
2. Connect the earth ground terminal of the DS7400Xi control panel and the door and to the threaded
ground stud on the base of the enclosure, as shown below. Also connect the earth ground of the
transformer to the threaded ground stud on the base of the enclosure.
