Figure 2:

Detaching a plug-in unit from the case

The protection relay 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.
