5. Installation
IMPORTANT: Ensure all power is disconnected before beginning installation.
Physical Installation Steps
- Wire Preparation: Strip the insulation from the wires to the appropriate length.
- DIN Rail Mounting: Mount the device onto a standard 35mm DIN rail. Ensure the device is in the 'OFF' position during mounting.
- Module Connection (if applicable): Connect any additional modules as required.
- Secure Wiring: Insert the prepared wires into the appropriate terminals.
- Tighten Terminals: Use a screwdriver to securely tighten all terminal screws.
- Engage LOCK: If manual operation is not desired during maintenance, engage the LOCK safety padlock.
- Test: Perform initial tests before full power-up.
- Switch ON/OFF: Operate the main switch to ON or OFF as needed.
Wiring Diagrams
RS485 Wiring: Connect terminals as shown in the diagram. Single-phase/Three-phase L can take ABC as the power cord.
MCB Adaptation
NOTE:
- Confirm the handle length with sales at the time of purchase for GYAR9-1P/2P.
- MCB-Preferred iC60 Series in Adaptation; other models can be custom adapted.
6. Operating Instructions
Manual Mode
In manual mode, the circuit breaker can be manually opened and closed using the main switch. This mode is typically used for initial setup or maintenance.
Automatic Mode
To activate automatic reclosing, switch the device to 'AUTO' mode. The device will then automatically attempt to reclose after a fault, following a timed sequence:
- First Reclosing: After 10 seconds.
- Second Reclosing: After 60 seconds.
- Third Reclosing: After 300 seconds.
If the fault persists after the third reclosing attempt, the device will remain open and require manual intervention.
External Control
The device supports external control for opening and closing via connected buttons or a remote system (e.g., via MODBUS 485). This allows for flexible integration into larger control systems.
7. Maintenance
Safety Lock for Maintenance
When performing maintenance on the circuit, always pull up the safety lock in manual mode. This prevents accidental reclosing and ensures safety. At this time, manual closing is not possible.
Resetting Reclosing Count
If the reclosing count needs to be reset to zero (e.g., after resolving a persistent fault), follow these steps:
- Ensure the safety lock is pulled up.
- Quickly toggle the button left and right three times. The digital display will show '00' indicating the count has been reset.
Fault Storage and Monitoring
The device supports local storage of fault data. This data can be read when the remote communication function is restored, aiding in diagnostics and troubleshooting.
8. Troubleshooting
- Device does not close manually: Check if the safety lock is engaged. If it is, disengage it or follow the reset procedure if necessary.
- Device does not reclose automatically: Verify the device is in 'AUTO' mode. Check the reclosing count on the digital display. If the count has reached its limit (e.g., after three attempts), reset it as described in the Maintenance section.
- Persistent tripping: If the device continues to trip after reclosing attempts, there may be a persistent leakage signal or fault in the circuit. Identify and resolve the underlying electrical issue.
- When equipment needs service: Always put the switch to 'MANU' (Manual) mode before performing any service or maintenance to prevent unexpected reclosing.
9. User Tips
- Type A vs. AC Type: The main difference lies in the types of residual currents they can detect. AC type RCDs detect sinusoidal alternating residual currents. Type A RCDs detect sinusoidal alternating residual currents and pulsating DC residual currents. For photovoltaic systems, which can produce pulsating DC currents, a Type A RCD is often recommended for comprehensive protection. Consult a qualified electrician to determine the appropriate type for your specific installation and load characteristics.
- Regular Testing: Periodically press the 'Test' button on the device to ensure its proper functioning and verify that it trips correctly.
- Remote Monitoring: Utilize the MODBUS 485 remote communication function to monitor the device's status and receive alerts, especially in critical or remote installations.
