Ambient temperature 0... 50°C; 6. Relative humidity 20... 85%.

1. Do not run input wires together with power cables; 2. External components (e.g., zener barriers) connected between sensor and input terminals may cause errors; 3. Connect a shielded cable to one point only; 4. Pay attention to the line resistance; 5. Connect power last; 6. Use No 16 AWG or larger wires rated for 75°C; 7. Use copper conductors only; 8. Before connecting to power line, ensure line voltage is equal to the voltage on the identification label; 9. The power supply input is not fuse protected, provide a T type 1A, 250V fuse externally.
