5.6.3 Checking the insulation monitoring unit (if available)<br />
CAUTION<br />
If your generator is equipped with the option "Insulation<br />
monitoring with switching-off", the correct function of the<br />
insulation monitoring unit has to be checked every working day.<br />
The generator may only be taken into operation, if the correct<br />
function of the insulation monitoring unit has been confirmed.<br />
Proceed as follows to check the insulation monitoring unit (refer to Figure 27 for<br />
the location of the control elements <strong>and</strong> indicators):<br />
1. Unplug all devices <strong>and</strong> cables connected to the generator.<br />
2. Start the engine. The check must be performed while the generator is<br />
running.<br />
3. Open the cover of the control box <strong>and</strong> switch on the insulation monitoring<br />
unit (position "ON" or "I").<br />
4. Push the red test push-button which is at the same time used as an indicator.<br />
Now the insulation monitoring unit must trip.<br />
5. Check whether the insulation monitoring unit has tripped <strong>and</strong> the red<br />
indicator "FAULTY INSULATION" is on.<br />
NOTE<br />
If the insulation monitoring unit does not trip or if the "FAULTY<br />
INSULATION" indicator does not light, the generator must not<br />
be used any longer. In this case, mark the generator as<br />
defective <strong>and</strong> have it repaired (refer to section 7 on page 92).<br />
6. Stop the engine to reset the insulation monitoring unit.<br />
7. Switch on the insulation monitoring unit again (position "ON" or "I") <strong>and</strong><br />
correctly close the cover of the control box (tighten the locking screws by<br />
h<strong>and</strong>).<br />
8. If the check was successful the generator is now ready for operation.<br />
