 A power supply with a Class 2 or SELV rating should be used. A Class 2 or SELV power supply provides
isolation to accessible circuits from hazardous voltage levels generated by a mains power supply due to
single faults. SELV is an acronym for "safety extra-low voltage." Safety extra-low voltage circuits shall
exhibit voltages safe to touch both under normal operating conditions and after a single fault, such as a
breakdown of a layer of basic insulation or after the failure of a single component has occurred.
 If the power supply will be mounted in a hazardous location, it must be rated for Class I, Div. 2 by an
OSHA recognized NRTL, such as UL or FM.
 Using the terminal block provided, connect the power supply's +24Vdc lead to terminal 2 and the Common
lead to terminal 1. See figure below. Plug the terminal block into the connector located on the bottom
of the interface.
