Use the wedge-shaped keying tabs and U-shaped keying bands to
prevent connecting the wrong wires to your module.

on the RTB. For example, if you key the first position on the module,
leave the first position on the RTB unkeyed.
1. To key the module, insert the U-shaped band, as shown.
2. Push the band until it snaps in place.
3. To key the RTB or IFM, insert the wedge-shaped tab with
rounded edge first, as shown.

Reposition the tabs to rekey future module applications.
