Safety Technical Disclosure for Small Busbars in Computer Rooms
Adequate spacing prevents short circuits and enhances system safety: Bare copper busbars: Minimum clearance ≥20mm to avoid phase-to-phase or phase-to-ground faults. Insulated busbars: Insulation allows for reduced clearance but must meet IEC 60664or UL 746Cdielectric strength. A manufacturer of electrical automation panels is not required to use a certified busbar system or to subject it to short-circuit tests, provided that it complies with Table G3. Since 1989 the standard for Industrial Control Equipment, UL 508 had been the primary industry standard to which components are certified in the U. Procedure: UV Test according to ISO 4892 – 2 method A; 1000 cycles of 5 min of watering and 25 min. The value of temperature and humidity for the test are (65±3)oC and (65±5) %. The notices referring to your personal safety are highlighted in the manual by a safety alert symbol, notices referring only to property damage have no safety alert.
