- Installation Guidelines
4.1 설치 단계
- 준비
Measure route, reserve 15% extra length
Use proper cutter, bender, 그리고 52/53 series HD fittings
- Cutting & bending
Cut squarely with special conduit cutter
Bend slowly, min. bending radius ≥ 84 mm
Support every ≤ 3 중, add supports at bends
- Fitting installation
Strip ~15 mm jacket to expose steel core
Insert into fitting and twist to lock
Tighten nut fully for liquid‑tight seal
- Fixing & cabling
Heavy‑duty clamps, spacing ≤ 1.2 중
Leave 50 mm expansion gap at equipment
Clean interior before pulling cables
4.2 안전 규칙
Ground conduit properly, grounding resistance ≤ 10 오
Keep ≥ 150 mm from heat sources
Use protective sleeves when passing through walls/floors
For Zone 2 hazardous areas, use explosion‑proof fittings
