5. Installation

IMPORTANT: Installation must be carried out by a qualified electrician. Ensure all power is disconnected before commencing installation.

Mounting: The EKL13 RCBO is designed for DIN rail mounting. Securely attach it to the DIN rail within your electrical distribution board.
Wiring: Refer to the product wiring diagram (Figure 3) for correct connections.

Connect the incoming live (L) and neutral (N) wires to the top terminals.
Connect the outgoing live (L) and neutral (N) wires to the bottom terminals.
Ensure all terminal screws are tightened securely to prevent loose connections and overheating.

Verification: After wiring, double-check all connections for correctness and tightness.

6. Operation

Switching ON/OFF:
- To switch the circuit ON, push the product handle upwards to the "ON" position. The indicator window will show green.
- To switch the circuit OFF, push the product handle downwards to the "OFF" position. The indicator window will show red.
Automatic Tripping: In the event of an earth leakage fault, short circuit, or overload, the RCBO will automatically trip to the "OFF" position, disconnecting the power supply to the protected circuit.

7. Maintenance

Regular maintenance ensures the continued reliable operation of your EKL13 RCBO.

Monthly Test: Press the "Test Monthly" button (marked 'T') on the front of the RCBO. The device should trip immediately, indicating that the residual current protection mechanism is functioning correctly.

If the device does not trip, it may be faulty and should be replaced by a qualified electrician.
After testing, reset the RCBO by pushing the handle to the "ON" position.

Visual Inspection: Periodically inspect the RCBO for any signs of physical damage, discoloration, or loose connections.
Cleaning: Keep the device clean and free from dust and debris. Use a dry, soft cloth for cleaning. Do not use liquids or abrasive cleaners.

8. Troubleshooting

Problem	Possible Cause	Solution
RCBO trips frequently	Earth leakage fault, short circuit, or overload in the protected circuit.	Disconnect all appliances from the protected circuit. Reset the RCBO. If it holds, reconnect appliances one by one to identify the faulty one. If it still trips with no load, there might be a wiring fault. Consult a qualified electrician.
RCBO does not trip when test button is pressed	Faulty RCBO.	Immediately replace the RCBO with a new one. Consult a qualified electrician.
RCBO cannot be switched ON	Persistent fault in the circuit, or internal damage to the RCBO.	Ensure there are no active faults (leakage, short, overload). If the fault is cleared and it still won't reset, the RCBO may be damaged. Replace it.

9. User Tips

Based on common inquiries and user experiences:

Type A vs. Type C: The EKL13 is specified as both "A Type" and "C Curve". "Type A" refers to the residual current detection capability (detects AC and pulsating DC residual currents), while "C Curve" refers to the tripping characteristic of the overcurrent protection (suitable for general purpose circuits with moderate inrush currents).
Professional Installation: While the device is user-friendly, electrical work can be dangerous. Always opt for professional installation to ensure safety and compliance.
