Duct Applications
See Senva’s Duct Mount Gas (1) One side of transformer secondary is connected to signal common. Dedicated transformer is recommended. No
sensing application note to learn mains circuit connection allowed. In addition, it is required to use an isolated power supply that is certified by a na-
about the use of duct-mounted tional or international standard (i.e. UL). Use of a Class 2 LPS power supply or greater is required.
