Note
A DPST (Double Pole, Single Throw) on/off switch must be installed to safely disconnect the power
supply. Fit the DPST switch as close as possible to the Rosemount 2130. Keep the DPST switch free of
obstructions. Label the DPST switch to indicate it is the supply disconnection device for the
Rosemount 2130.
