3. Operation<br />
If the automatic circuit-breaker is tripped out during overload of the experiment setup:<br />
• Disconnect experiment setup from the mains by switching the mains switch to [OFF]<br />
• Correct fault source<br />
• Reset the automatic circuit-breaker by setting the switch to [I]<br />
Test the function of the RCCB:<br />
• Set mains switch to [ON]<br />
• Press the pushbutton [T] on the RCCB circuit-breaker<br />
• If the RCCB circuit-breaker is tripped, operation is guaranteed.<br />
If the RCCB circuit-breaker is tripped by a fault current in the experiment setup<br />
• Disconnect the experiment setup from the mains by switching the mains switch to [OFF]<br />
• Correct fault source<br />
• Reset the RCCB circuit-breaker by setting the switch to [I]<br />
If the reverse-polarity control lamp lights up:<br />
• Pull out the mains plug<br />
• Replug the mains plug with the correct polarity (rotate)<br />
