1. Verify the module's order code (3BHE012436R0001) and revision against the system spare-parts list before installation.
2. De-energize the PEC800 cabinet and confirm DC-link discharge before handling; use ESD precautions.
3. Install the module in its designated PEC800 power slot; seat connectors fully.
4. Verify input voltage within range (85–264 V AC / 120–370 V DC) and output 24 V DC ±1% at the backplane.
5. Confirm redundancy behavior — simulate a single-supply failure during commissioning and verify automatic switchover without interrupting the load.
