Precautions

1. Installation Norms: HITACHI LPU100A is installed with 35mm standard DIN rail card, ensure the module is clamped firmly during installation, and keep a distance of ≥5cm from the surrounding high-power heating equipment to ensure good heat dissipation; the module is IP20 protection grade, must be installed inside the closed industrial control cabinet to avoid dust and water vapor intrusion.
2. Wiring Operation: Strictly distinguish the AC input terminal, DC 24V output terminal and DC 5V output terminal during wiring, and mark the wiring clearly; the input and output lines use copper core wires with appropriate cross-sectional area (≥1.5mm²), and the wiring terminals are tightened to avoid poor contact caused by heating.
3. Hot Swap Operation: Although hot swap is supported, it is necessary to cut off the load of the corresponding output channel first before plugging and unplugging the module to avoid damage to the module and connected equipment caused by instantaneous current impact; hold the module buckle when plugging and unplugging, and it is strictly forbidden to pull the power line directly.
4. Load Matching: The connected load power of the module shall not exceed the rated output power (100W) of HITACHI LPU100A, and the single-channel output current shall not exceed the rated current (24V/4A, 5V/2A) to avoid overloading and damage to the module.
5. Grounding Requirement: The module must be reliably grounded (ground resistance ≤4Ω), and the grounding wire uses copper core wire with cross-sectional area ≥2.5mm²; reliable grounding can effectively improve the anti-electromagnetic interference performance of the module and avoid static electricity damage.
6. Environmental Protection: Avoid placing the control cabinet with HITACHI LPU100A in a high-temperature, high-humidity, strong-vibration or corrosive gas environment; keep the control cabinet well-ventilated, and regularly clean the dust inside the cabinet to avoid dust accumulation affecting the module’s heat dissipation.
7. Fault Handling: When the module’s fault indicator light is on, cut off the input power supply in time and check the load circuit for short circuit, overcurrent and other abnormalities; do not disassemble the module by yourself for repair, and contact professional after-sales personnel for maintenance.
8. Parallel Use: HITACHI LPU100A does not support parallel use of multiple modules to increase output power, and parallel connection will cause mutual interference between modules and damage the equipment; if higher power supply is needed, select Hitachi’s high-power PLC power supply module of the same series.
9. Daily Maintenance: Regularly check the module’s running indicator lights (power light/normal light), wiring terminals and shell temperature during daily maintenance; if the indicator light is off, the terminal is loose or the temperature exceeds 70℃, stop the machine for troubleshooting immediately.
10. Storage and Transportation: Unused HITACHI LPU100A should be stored in a dry and ventilated environment with a temperature of -10℃~+40℃ and a humidity of ≤70%RH, avoiding direct sunlight, rain and violent collision; use shockproof and moisture-proof packaging during transportation, and protect the wiring terminals with insulating caps to avoid short circuit.
