Step Action
1
Make sure the power supply leads have an adequately dimensioned
protective device (breaker).

Install a breaker in the power supply line or a switched receptacle
near the gas analyzer to make sure the gas analyzer can be
completely separated from the power source. Mark the breaker so
that its relationship to the protected device is clear.
