5. Setup and Installation
Before You Begin:
- Ensure the main power supply to the installation area is completely disconnected.
- Verify that the device specifications (e.g., voltage, number of poles) match your electrical system requirements.
- Prepare appropriate tools and personal protective equipment.
Installation Steps:
- Mounting: The CHLT-D100 is designed for standard 36MM DIN rail mounting. Snap the device securely onto the DIN rail within your distribution box or circuit breaker panel.
- Wiring: Connect the device according to the wiring diagram provided with your product or standard electrical practices. Ensure correct polarity: '+' for the positive wire and '-' for the negative wire. Incorrect wiring can damage the device or the electrical system.
- Grounding: Ensure a robust and low-impedance connection to the main grounding system. Proper grounding is critical for the effective operation of the surge protective device.
- Verification: After completing all connections, double-check all wiring for tightness and correctness.
- Power Restoration: Once installation is verified, close the automatic circuit breaker (fuse) switch to restore power. Observe the working status indicator on the device.

6. Operation
The Tyenaza CHLT-D100 operates automatically to protect your electrical system. When an overvoltage event (e.g., lightning strike, power surge) occurs, the device diverts the excess electrical energy safely to the ground, preventing it from reaching and damaging connected equipment. The device features a visual indicator on each module:
- Green Indicator: Indicates normal operation and protection is active.
- Red Indicator (or absence of green): Indicates that the module has absorbed a significant surge and needs replacement.

7. Maintenance
The CHLT-D100 is designed for minimal maintenance. Regular visual inspection is recommended to ensure continued protection:
- Periodically check the visual indicator on each module. If the indicator is red (or the green is absent), the module has reached its end-of-life and requires replacement.
- Ensure that all connections remain tight and free from corrosion.
- Keep the device and its surroundings clean and free from dust or debris.
Module Replacement:
If a module indicator turns red, it must be replaced to restore full protection. This is a plug-in modular design, allowing for easy replacement of individual modules without disconnecting the entire device from the DIN rail. However, always disconnect the main power supply before replacing any module to prevent electrical hazards.
8. Troubleshooting
Most issues related to the surge protective device can be identified by its visual indicator:
- Indicator is Red (or Green is Absent): This signifies that the internal protection components have been activated and are no longer functional. The module needs to be replaced.
- No Power to Protected Equipment: If the SPD indicator is green but there is no power to protected equipment, check the upstream circuit breaker or fuse. The SPD itself does not interrupt power unless it has failed in a short-circuit condition, which would typically result in a red indicator.
- Frequent Red Indicators: If modules are frequently turning red, it may indicate a persistent overvoltage issue in your electrical system or that the SPD is undersized for the level of surges it is experiencing. Consult a qualified electrician to assess your electrical system and potentially upgrade the SPD.
For any issues not covered here, or if you are unsure about troubleshooting steps, contact a qualified electrician or the manufacturer's support.
