Load Protection Switch
5
Interlock Connection
The Interlock connection is design to be controlled by an external switching
circuit capable of 200mA. When continuity is present across the two terminals,
the RF switch will close, allowing RF power to travel in the transmission line.
1. Using number 22 AWG (or heavier) wire, attach solder-less ring terminals to
the wire.
2. Remove protective cover from the Load Protection Switches interlock
terminal.
3. Connect one end of the interlock wires to the Load Protection Switch’s
terminal strip.
4. Install the terminal’s protective cover.
Figure 4 Terminal Connections
Note:
For long wire runs, twist the interlock wires together to
minimize potential false deactivation.
5. Connect the other end of the interlock wires to the load’s interlock terminal
strip.
Note:
DC input power must be provided to the Load Protection
Switch for it to properly activate.
6. Connect the DC power supply to the input connector on the Load
Protection Switch.
