Installation notes
- The CHARM Fused Injected Power Terminal Block installs on the CHARM Baseplate and holds a single CHARM. It provides the keying and field wiring for the CHARM and bussed power connections to implement high-side outputs and dry contact inputs for isolated Discrete CHARMs. Bussed power is wired to the CHARM Address Terminal.
- The terminal block's fuse protects the field wiring from short circuits.
- The fuse cannot be replaced when the terminal block is under power in a hazardous environment.
- The CHARM Fused Injected Power Terminal Block's keying mechanism sets itself to match the inserted CHARM.
- To reset the keying mechanism, remove the CHARM Fused Injected Power Terminal Block from the CHARM Baseplate, flip the terminal block 180°, and use your fingers to push the two keying posts completely in so they are sub flush to the bottom face of the terminal block. Sub flush is the neutral position. You will hear a click when the posts are in the neutral position. When the posts are in the neutral position, the terminal block can receive a different CHARM type.
- The following CHARMs can use the CHARM Fused Injected Power Terminal Block:
