EPC TERMINAL ASSIGNMENT
* On tethered installations the RCBO and contactor should be rated according to the maximum current capacity of the EPC. On
free
-
cable installations the RCBO and contactor should be rated 16A.
** DC capable: For 120
-
370V DC on L, connect N to ground (0V).
TERMINAL
DESCRIPTION
L (LINE)
This is where the AC
‘
live
’
or
‘
line
’
connection is made (90
-
264V @ 50/60 Hz AC)**
N (NEUTRAL)
This is where the AC
‘
neutral
’
connection is made (90
-
264V @ 50/60 Hz AC)**
0V (GROUND)
This is where the
‘
ground
’
connection is made**
HL (HATH LOCK) /
ML (MOTOR LOCK)
ExxF32: Provides 12V continuously to energise solenoid for hatch lock (HL)
ExxF33: This provides 12V 300mA for 500 ms to engage the lock for motorised
locks (ML)
MU (MOTOR UNLOCK)
ExxF32: This provides return path for the solenoid circuit (OV)
ExxF33: This provides 12V 300mA for 500 ms to disengage the lock (MU)
HF (LOCK FEEDBACK)
Reads lock feedback for motorised locks
NC (NOT CONNECTED)
P1
Relay 1 live from RCBO*
P2
Relay 1 coil on the contactor*
P3
Relay 2 live from 32A RCBO
P4
Relay 2 coil on the 32A contactor
P5
Relay 3 live from 63A RCBO
P6
Relay 3 coil on the 63A contactor
PP (PROXIMITY PIN)
This connects to the PP connector on the IEC61851 EVSE connector
GN (GREEN LED)
For external LED connection for green indication (5V 30mA)
BL (BLUE LED)
For external LED connection for blue indication (5V 30mA)
RD (RED LED)
For external LED connation for red indication (5V 30mA)
CP (CONTROL PIN)
This connects to the CP connector on the IEC61851/J1772 EVSE connector
IC (INPUT CURRENT PIN)
This connects to one side of the IC resistor, switch, or dial (the other side to 0V)
