AC Power Input and DCS Power Distribution
The PW482-S01 receives AC power within its specified input range. Before installation, verify that the host unit supports this power supply model and that the available supply voltage and frequency meet its requirements.
In redundant configurations, two power supply modules may be used where the host hardware provides the required arrangement. Redundancy does not independently establish hot-swap capability or a specific switchover time. Confirm these functions in the applicable Yokogawa hardware documentation.
Frequently Asked Questions
Q: What AC input does the PW482-S01 support?
A: The supplied specifications state 220 to 240 V AC, with a tolerance of +/- 10%, at 50/60 Hz +/- 3 Hz.
Q: Can the PW482-S01 operate in a redundant configuration?
A: Dual-module redundancy is supported where the compatible host unit provides the required configuration. Verify the host unit’s installation and power distribution requirements before commissioning.
Q: What should be checked before replacing the module?
A: Confirm the full model designation, host unit compatibility, input voltage, connector arrangement, and required power configuration. Follow the system manufacturer’s shutdown and electrical isolation procedures.
Field Installation Guidelines
- Verify the complete part number PW482-S01 against the host unit’s approved hardware documentation.
- Isolate the AC supply before removing or installing the module. Follow the host system’s prescribed replacement procedure.
- Inspect the module and backplane connector for contamination, bent contacts, or mechanical damage before installation.
- Confirm that the supply voltage and frequency remain within the specified input limits.
- Keep power wiring separated from low-level analog signal and communication wiring in accordance with the cabinet wiring design.
- Verify grounding, protective bonding, and electrical clearances against the manufacturer’s installation requirements.
- Do not assume hot-swap support or a defined redundancy switchover time without model-specific documentation.
- After installation, verify the power supply status and the operation of the connected control system units.
