Checking the residual current circuit breaker

Introduction
Residual current circuit breakers disconnect the monitored
circuit from the remaining grid in the event
of a certain differential electric current. Test the residual current
circuit breaker at regular intervals in
order to simulate this error.
Maintenance interval
Every 6 months.
Illustration
The following diagram shows the location of the residual current
circuit breaker -5F3 1 in the control cabinet.
Requirements
• The service switch is in the ON position; the gas sampling
probe is completely retracted from the kiln (see Operating
the service switch on page 100).
• Tools required: Control cabinet key to open the control
cabinet
Instructions
Perform the following steps for residual current circuit breaker:
1. Open the control cabinet.
2. Press the test button "T"
breaker -5F3 to start the self-test (Picture: 2-pole residual
current circuit breaker for normal grid).
