- Downsized alternative: 6EP1436-2BA10 (20あ / 480W) for half-load applications
VIII. 設置禁止事項 & トラブルシューティングガイド
Forbidden Operations (Critical Restrictions)
- Horizontal or upside-down mounting is strictly prohibited; blocked cooling air duct triggers rapid over-temperature protection
- Long-term power-on with direct output short circuit will cause continuous hiccup power derating
- Long-term operation with missing input phase accelerates aging of internal power components
- Do not install alongside high-power inverters without partition plates to avoid EMC interference
Common Fault Matrix
| 現象 | 根本的な原因 | 対策 |
| Green light off, no 24V output | 3-phase power loss, サーキットブレーカーが落ちた, internal overheating | Check 3-phase incoming voltage; power off and cool down then restart; clean dust in air duct |
| Green light flashing, output voltage drop | Output overload / 短絡 | Disconnect loads and locate short circuit by segmentation; limit total load within 40A |
| Output voltage below 23V under load | Undersized cables causing excessive voltage drop | Thicken 24V main cables; add auxiliary power supplies nearby |
| Frequent over-temperature shutdown | Ambient temp >55℃, clogged air duct, fully enclosed cabinet | Install cabinet cooling fan, lower ambient temperature, reserve ≥50mm top & bottom ventilation clearance |

- Cabinet Installation Clearance Requirements
- 取付レール: Standard 35mm TH35 DIN rail, 垂直設置 (terminals downward)
- トップ & bottom ventilation clearance: Reserve at least 40mm for heat dissipation; derating mandatory if ambient temp exceeds 55℃
- Side-by-side mounting: Units of same model can be tightly arranged without extra spacing
補足
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.
