for Class 2 and Class 1 wiring considerations.
Primary/Secondary Switch (IQ48 only)
When using any combination of two 0–10V, DALI, or
Contact Input option cards in a Sensor IQ you will need to
position the Primary/Secondary switch prior to startup. The
Primary/Secondary switch controls which set of breakers
responds to each option card.
Option Card 1 will always control circuits 1–24. If the
Primary/Secondary switch is in the “OFF” position, Option
Card 2 will also control circuits 1–24. If the Primary/
Secondary switch is in the “ON” position, Option Card 2 will
control circuits 25–48. See the examples in the tables below.
