Safety Standards For Fan Coil
Dec 05, 2016

1. fan-coil safety requirements should be consistent with the provisions of ZBJ72-018.
2. fan coil electrical wiring connections should be clean, firm, wire through hole and plug should be used insulation tubes or other appropriate protective measures.
3. wind machine disc tube by in at room temperature, and often wet conditions Xia, with 500V insulation resistance meter determination wind machine disc tube charged part and non-charged metal part Zhijian of insulation resistance and by table 6 provides of condensation water test workers condition continuous running 4H Hou, with 500V insulation resistance meter determination wind machine disc tube charged part and non-charged part and non-charged metal part Zhijian of insulation resistance inspection, its cold, and hot state on to insulation resistance value should not is less than 2M ω.
4. fan-coil electric strength according to the fan-coil speed respectively under the "connected" position, charged in part with non-conductive parts between 1500V AC voltage rated frequency. Starting voltage should be less than half the value, and then quickly promoted to full value, 1min. In mass production, 1800V and 1s available time instead.
