Normally Open Sensor Input Wiring
Wire each normally open sensor on top of the factory-supplied jumper. Loosen the screw and
slide the wire lead into the terminal without removing the jumper (either side of jumper).
Normally Closed Sensor Input Wiring
Remove the factory-supplied jumper completely. Connect the two sides of the normally closed
sensor to the two terminals of the terminal block.
NOTE: Switches connected to the S1501 Sensor Input Terminal Block
must be dry contact mechanical switches.
Intrinsically Safe Barrier Wiring
Important (normally open sensor only): Secure area of hazardous
conditions before opening barrier cover or operating sensor contacts.
a. Run Sensor switches wiring through conduit and isolate from the S1501 terminal
block(s) with an explosion-proof barrier.
b. For wiring refer to the following typical wiring diagrams.
