Figure 2:
Detaching a plug-in unit from the case
The IED features an automatic short-circuit mechanism in the CT
connector. Therefore, detaching the plug-in unit will not open the
secondary circuit of the CT which could cause dangerously high voltages.
Do not touch terminals inside the case after removing the plug-in unit.
Live terminals can be inside the case.
