Functional Grounding; Relay Outputs - Mainpine EPC Operating Instructions Manual

CONNECTION

5.3 FUNCTIONAL GROUNDING

VEHICLE INTERFACE ACCORDING TO IEC 61851
1. Connect the terminals "CP" and "PP" (on free versions only) directly to the vehicle connector .
2. First connect the ground connection of the vehicle interface to the 0V reference point and then route this potential from there .
DANGER: NEVER USE THE TERMINALS OF THE MAINPINE EPC CHARGING
CONTROLLER AS A 0V REFERENCE POINT.
Always route this externally from the device! The 0V reference point within the plant must be dimensioned according to the
anticipated current of the plant itself . The EPC connection to the 0V is only a functional ground . Failure to observe this notice can
result in electric shock or damage to property .

5.4 RELAY OUTPUTS

We recommend single fusing with 230/400 V 10 kA circuit breakers, 1-pin, C, 2 A, T = 70 mm, item no .
SHUTDOWN OF POWER BRANCH
According to IEC 61851, a shutdown of the power branch on completion of the charging process within 100 ms is required . The Mainpine
EPC Charging Controller 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.
Failure to observe this notice can result in death or serious physical injury .
