Depending on the model being installed, the fuse platform will have either of two types of alarm connectors on the rear side of the platform:

•Screw-down barrier terminal strip

•Wire wrap pin

•Screw-down barrier terminal strip: The terminal screw size is 3-48. Terminate wire leads with crimp-on spade lug or ring connectors that have a maximum width of 0.200 (5.080

mm)or use #16 to #30 AWG copper wire without lugs (insulation stripped back). In selecting wire size, follow local code referring to the ampacity guidelines provided in Appendix A of this manual.Tighten the terminal screws to approximately 9 pound-inches (1 Newton-meter) of force.

•Wire-wrap terminal: Wrap terminal block pins using #22 to #26 AWG copper wire with insulation stripped back. In selecting wire size, follow local code referring to the ampacity guidelines provided in Appendix A of this manual.
