注意事项 PRECAUTIONS

1 Mounting: Follow the outline drawing for correct 35mm DIN Rail or Panel Mount installation

2 Power Supply: Do not exceed the 24VDC ±10% voltage range; ensure supply current stays within 25mA maximum

3 Output Load: For the 0-10VDC output, use a load resistance of ≥2kΩ to maintain performance

4 Operating Environment: Avoid temperatures outside the 0°C to +60°C range; do not expose to vibration beyond IEC60068-2-6 standards

5 Electrical Safety: Ensure isolation voltage limits are not violated; install a nearby switch or circuit breaker as per safety guidelines

6 Usage Limits: Do not apply input currents beyond the 0-15AAC range; use external current transformers if extending the range

7 Maintenance: Clean only with a water-dampened cloth; avoid harsh chemicals

8 Compliance: Adhere to UL, CSA, IEC standards during installation; refer to the connection diagram on the case for correct wiring
