(POTTER <br />The Symbol of Protection <br />Breaking Excessive Rod Length <br />Fig 10 <br />Switch Terminal Connections <br />Clamping Plate Terminal <br />Fig 11 <br />0A�6 <br />�g <br />An uninsulated section of a single conductor should not be looped around <br />the terminal and serve as two separate connections. The wire must be <br />severed, thereby providing supervision of the connection in the event that <br />the wire become dislodged from under the terminal. Failure to sever the <br />wire may render the device inoperable risking severe property damage <br />and loss of life. Do not strip wire beyond 3/8" of length or expose an <br />uninsulated conductor beyond the edge of the terminal block. When using <br />stranded wire, capture all strands under the clamping plate. <br />All conduit and connectors selected for the installation of this product <br />shall be suitable for the environment for which it is to be used and shall be <br />installed to the manufacturer's installation instructions. For NEMA4, 4X, 61 <br />6P installations, the cover screws are recommended to be tightened to 15 in - <br />Its; minimum and the trip rod locking screw tightened to 5 in-lbs minimum <br />to Drorerly seal the enclosure. <br />Typical Electrical Connections <br />Fig 12 <br />XR <br />NC N NO NC COM 1 <br />Supervisory switches have a normal service life of 10-15 years. <br />OOO However, the service life may be significantly reduced by local <br />environmental conditions. <br />OSYSU Series <br />Outside Screw and Yoke Value <br />Supervisory Switch <br />Ordering Information <br />Model <br />Description <br />Stock No. <br />OSYSU-1 <br />Outside Screw & Yoke <br />1010102 <br />Supervisory Switch <br />(Single switch) <br />OSYSU-2 <br />Outside Screw & Yoke <br />1010202 <br />Supervisory Switch <br />(Double switch) <br />OSYSU-2 <br />Outside Screw & Yoke Supervisory <br />1010210 <br />CRH <br />Switch (Double Switch).
