EPC 2.0 TERMINAL ASSIGNMENT
TERMINAL DESCRIPTION
L (LINE) This is where the AC ‘ live ’ or ‘ line ’ connection is made (207 - 257V @ 50Hz AC)*
N (NEUTRAL) This is where the AC ‘ neutral ’ connection is made (207 - 257V @ 50Hz AC)*
0V (PE)
This is where the Protective Earth ( ground ) and 0v connections for the RCM and
IC resistor circuits are made*
LK+
Configuration is dependent .
• Provides a drive current to continuously energise the solenoid interlock
•
Provides a drive current to change the motorised interlock state to locked
( The signal is activated for 500ms and changes to pulsed 500ms intervals
until the lock is engaged. ( See LK FB )
Rating 12V 300mA
LK -
Configuration is dependent .
•
Provides a return path for the solenoid interlock drive current LK+.
• Provides a drive current to change the motorised interlock state to unlocked
( The signal is activated for 500ms and changes to pulsed 500ms intervals
until the lock is disengaged. ( See LK FB )
Rating 12V 300mA
LK FB If lock feedback has been selected via DIP switch 4
COM Relay 1 & 2 (common) Live from integrated electrical protection or mains terminals
P1 Relay 1 to coil on the EVSE ( 16A / 32A ) Contactor
P2 Relay 2 to coil on the Auxiliary Contactor
PP ( Proximity Pilot ) Connection for the IEC61851 / J1772 EVSE Connector ( see Proximity )
CP ( Control Pilot ) Connection for the IEC61851 / J1772 EVSE Connector ( see Pilot Circuit )
IC ( Input Current )
The limiting Input Current to the EV , Resistor connection ( The other connection
of the Resistor is the 0v (PE) terminal.
12V 12V Supply to provide power to the RCM
FLT
Connects to RCM ‘ Fault out ’. The EPC 2.0 reads if fault condition reported by the
RCM
TST
Connects to RCM ‘ Test ’ . The EPC 2.0 uses this to check the operation of the
RCM before each charging session commences.
CT1 ( PEN)
Connection for current transformer 1; measures earth current for PEN Loss detec-
tion (or base load for load sharing in EPC 2.0 + models )
CT2 Connection for the other side of current transformer 1
NC Not Connected . Not used .
CT3
Connection for current transformer 2; measures EVSE current draw in EPC 2.0 +
models (not used in the basic EPC 2.0 models)
CT4 Connection for the other side of current transfer 2
RSA RS485 connection available in EPC 2.0 + models
RSB RS485 connection available in EPC 2.0 + models
RSG RS485 ground connection available in EPC 2.0 + models
•
* On tethered and free cable installations the electrical protection and contactor should be rated according to
the maximum current capacity selected via the DIP switch on the EPC 2.0 of either 16A or 32 A
