Working Voltage

1. Please note that the pick-up voltage and drop-out voltage may vary depending on environmental temperature and usage conditions.
   Product Code (Note: No specific product code details are provided in the source text after this heading)

2. Special attention must be paid: If a voltage exceeding the maximum applied voltage is applied, abnormal heating in the coil will occur, shortening the life of the insulation coating and potentially leading to coil burnout and interlayer short circuits. Also, ensure the ambient temperature does not exceed the specified operating range.

3. For this relay, if the rated voltage (or current) is applied to the coil and contacts for an extended period and then switched off and immediately back on, the coil temperature and resistance will be higher than normal. This results in an operating voltage higher than usual, exceeding the rated value ("thermal startup"). In such cases, appropriate measures should be taken, such as reducing the load current and energization time, limiting the ambient temperature, or preventing the application of coil voltage above the rated operating voltage.

4. When the coil is continuously energized for long periods, heat generated by the coil itself can accelerate insulation degradation.

5. The main contact ratings listed in the specifications are for resistive loads only. For inductive loads (L loads) with L/R > 1ms, implement surge absorption measures in parallel with the inductive load. Failure to do so may result in reduced electrical life or contact failure.

6. Use a fast rising edge to drive the coil of relays with a PCB board. (Equipped with a single-shot pulse generation circuit).

7. Special note for PCB-mounted relays: The coil current is automatically switched 0.2 seconds after turn-on. Repeated closing operations within less than 0.2 seconds may cause relay failure.

8. For relays without a PCB board (relays with a board have a built-in reverse voltage absorption circuit), it is recommended to use a varistor or a diode plus Zener diode as a protective circuit to absorb the reverse surge voltage when the relay coil is turned OFF. Note: Connecting a diode in parallel with the coil may slow the release time and potentially reduce the product lifespan.

Operating and Storage Environmental Conditions:

1. Temperature: -40°C to +85°C (Operating), -40°C to +95°C (Storage)

2. Humidity: 5%RH to 85%RH (Avoid icing and condensation)

3. Atmospheric Pressure: 86kPa to 106kPa

4. Regarding Condensation: Condensation is likely to occur during rapid temperature changes in high-temperature, high-humidity environments. Please note this may cause issues such as reduced relay insulation resistance.

5. Regarding Low-Temperature and Low-Humidity Environments: Prolonged exposure may cause plastic embrittlement. Please note.

6. General Storage Environment: Store in a dry, ventilated warehouse at 10-30°C and relative humidity ≤70%, free from harmful gases, chemical contamination, static electricity, moisture, and mechanical damage. Do not store with chemicals, acids, or alkaline substances. Avoid mechanical shock and heavy pressure during storage.

7. Do not use or store this relay in a vacuum, as this will accelerate the aging of the sealed structure.

Product Installation Precautions:

1. Always turn off the power and confirm no residual voltage before replacing the relay or wiring.

2. Polarity is critical: The relay's load terminals and the coil terminals of PCB-mounted relays have polarity. Connect strictly according to the terminal configuration/internal connection diagram above. Reversing the load terminal polarity will prevent achieving the switching characteristics described in this document. Reversing the coil terminal polarity on a PCB-mounted relay will damage the relay, rendering it unusable.

3. Tightening torque for screws at each location must be controlled within the specified range (Refer to Technical Parameters). Loose screws may cause abnormal heating during energization, potentially leading to fire. Exceeding the range may cause damage.

4. When installing connection lugs on load terminals, they must be installed in the direction shown in the diagram above. Using other connection methods will degrade insulation performance.

5. When wiring the coil terminals and load terminals, always use the screws provided with the product. Using other screws may prevent achieving the specified tightening torque and could cause abnormal heating and smoking during energization.

6. Do not use this relay where water, solvents, chemicals, or oil may contact the case or terminals. This could cause case resin aging or abnormal heating due to terminal corrosion/contamination. If electrolyte contacts the output terminals, electrolysis may occur between them, leading to corrosion or disconnection. For connected wiring busbars, products meeting the following nominal cross-sectional areas are recommended:

   • 40A Type: ≥ 15 mm²

   • 50A Type: ≥ 18 mm²

   • 80A Type: ≥ 30 mm²

   • 100A Type: ≥ 38 mm²

   • 120A Type: ≥ 48 mm²

   • 150A Type: ≥ 75 mm²

   • 200A Type: ≥ 100 mm²

   • 250A Type: ≥ 125 mm²

   • 300A Type: ≥ 150 mm²

   • 350A Type: ≥ 200 mm²

   • 400A Type: ≥ 240 mm²

   • 500A Type: ≥ 350 mm²

7. If installed near strong magnetic field sources (motors, transformers, speakers, magnets) or if multiple relays are installed very close together, the relay's operating characteristics may change, potentially causing malfunction. Furthermore, the arc discharge occurring during switching may be distorted by the magnetic field, causing flashover or insulation failure. Verify operation under actual installation conditions.

8. Avoid installation near heat-generating objects.

9. When installing multiple relays adjacent to each other, pay attention to mutual thermal interference causing abnormal heating and ensure sufficient insulation distance between the external terminals of different relays.

10. Never lift or carry the relay by its leads or connectors. This may cause lead loosening, breakage, and loss of conductivity.

11. When connecting connector terminals, use the specified mating connector on the counterpart side.

12. When installing busbars, do not apply excessive load to the terminals, as this may cause switching performance failure.
