6.6 SHUTDOWN OF POWER BRANCH
According to IEC 61851, a shutdown of the power branch on completion of the charging process within 3 s is
required. A shutdown of the power branch on transition from state C to state A is required within 100 ms. The
Viridian EPC 2.0 deactivates the relay output within this requirement after detecting the shutdown criterion.
WARNING: THE SHUTDOWN OF THE POWER BRANCH, IN PARTICULAR THE POWER
CONTACTOR, IS TO BE DESIGNED IN SUCH A WAY THAT THE ENTIRE IMPACT CHAIN DOES
NOT EXCEED THE REQUIRED 100 MS.
F
ailure to observe this notice can result in death or serious physical injury.

CONTROLLER AS A 0V REFERENCE POINT.
Always route this externally from the device! The 0V reference point within the plant must be
