11. Centralized 24V power supply scenarios requiring 3-phase industrial incoming power and high current loads

VII. Substituição & Capacity Expansion Solutions

1. Upgraded same-spec model: 6EP1437-3BA00 (with fault relay contacts for PLC diagnostic connection)
2. Capacity expansion: Parallel two 6EP1437-2BA10 units for max. 80UM / 1920W output
3. Downsized alternative: 6EP1436-2BA10 (20UM / 480C) for half-load applications

VIII. Installation Prohibitions & Guia de solução de problemas

Forbidden Operations (Critical Restrictions)

1. Horizontal or upside-down mounting is strictly prohibited; blocked cooling air duct triggers rapid over-temperature protection
2. Long-term power-on with direct output short circuit will cause continuous hiccup power derating
3. Long-term operation with missing input phase accelerates aging of internal power components
4. Do not install alongside high-power inverters without partition plates to avoid EMC interference

Nota Suplementar

Dimensions such as 250×180×92 and 145×145×150 shown on some foreign websites belong to the new PSU300S model 6EP1437-2BA20, which is incompatible with the legacy 6EP1437-2BA10. Cabinet cutout and DIN rail layout cannot be shared between them.
