Step Action

3 Connect the “–” wire (black) to the RTN terminal.

Connect the “+” wire (red) to the +27 V terminal.

4 Bundle wires together and place ferrite core around wires. Ensure that the wires are not being pinched

before closing and latching the ferrite core.

5 Slide ferrite core as close to the BTS connection as possible without causing stress. Use a tie–wrap on

the ferrite core side away from the connection. The tie–wrap holds the ferrite core in place.
