Ⅷ. 설치 금지 & 문제 해결 가이드
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
| 현상 | 근본 원인 | 대책 |
| Green light off, no 24V output | 3-phase power loss, 회로 차단기가 트립되었습니다., 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 / 단락 | 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
- Mounting rail: Standard 35mm TH35 DIN rail, 수직 설치 (terminals downward)
- 맨 위 & 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
보주
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.
