Setup and Installation
The DEfrat EKEPC2 controller is designed for DIN rail mounting within an appropriate electrical enclosure. Ensure all connections are secure and comply with electrical safety standards.
Wiring Connections
Refer to Figure 3 for terminal identification. The main connections include:
- L, N: Line and Neutral power input (240V AC).
- PE: Protective Earth ground connection.
- CP (Control Pilot): Communication line with the EV.
- PP (Proximity Pilot): Detects cable connection and current capacity.
- +5V, B-, A+: Power supply and communication lines for external modules (e.g., RFID reader).
- TST, NC, OV, FLT, 5V, RFID, CT1, CT2: Additional control and sensor inputs/outputs.
Ensure all wiring is correctly sized for 32A AC 240V operation and properly insulated. Use screw terminals for secure connections.
Operating Instructions
Once installed and powered, the DEfrat EKEPC2 operates automatically to manage the EV charging process. The front panel indicators provide status feedback.
Status Indicators (Refer to Figure 4)
- Ready (Green LED): Indicates the controller is powered on and ready to initiate a charging session.
- Charge (Green LED): Illuminates when an EV is connected and actively charging.
- Fault (Red LED): Indicates an error or malfunction in the charging system. Refer to the Troubleshooting section.
Current Selection
The controller allows for selection of maximum charging current: 10A, 16A, 20A, or 32A. This setting is typically configured during installation based on the charging station's capacity and local electrical regulations. The control method for this selection is via touch, likely through a button or switch under the transparent cover.
Maintenance
The DEfrat EKEPC2 controller is designed for reliable, long-term operation with minimal maintenance. However, periodic checks are recommended to ensure optimal performance and safety.
- Visual Inspection: Periodically inspect the controller and its wiring for any signs of damage, loose connections, or overheating.
- Cleaning: Keep the unit free from dust and debris. The transparent cover helps protect the internal components. Use a soft, dry cloth for cleaning. Do not use abrasive cleaners or solvents.
- Environmental Conditions: Ensure the operating environment remains within specified temperature and humidity ranges.
Always disconnect power before performing any maintenance or cleaning.
