  • Page 18: Mounting And Powering

    In some instances, an installer may be required to mount the XEV22D. There are no restrictions on the location of the XEV22D; however, the controller should be mounted in a location protected from moisture. Typically, mounting inside the electrical control panel of a package unit is acceptable.
