Power-limited and nonpower-limited circuit wiring must remain separated in the cabinet. All power-limited circuit
wiring must remain at least 0.25" away from any nonpower-limited circuit wiring. Furthermore, all power-limited
and nonpower-limited circuit wiring must enter and exit the cabinet through different knockouts and/or conduits.
A typical wiring diagram for the Sensiscan 200 is shown below.

Notes:
1)
The power-limited Remote Station Alarm Output and the nonpower-limited Municipal Box Output must not be used simultaneously.
2)
Mounting two or more modules in the same chassis position requires that all modules be either power-limited or nonpower-limited;
mixing is not allowed. Following is a list of Power-limited and Nonpower-limited modules:
