Electrical installation
Before use, check that suitable cable glands and blanking plugs are fitted and fully tightened.
Isolate supply before connecting the switch or removing the electronics.
The Protective Earth (PE) terminal must be connected to an external earthing system.

Direct load switching electronics cassette
Figure 2-22. Direct Load Switching (Two-wire, Red Label)
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.
Relay Connection Warning
The Rosemount 2130 requires a minimum current to operate (I
OFF
), which continues to flow when the
output is ‘off’. If selecting a relay to wire in series with the Rosemount 2130, ensure the drop-out voltage
of the relay is greater than the voltage generated across the relay coil when I
OFF
flows through it.
