During installation into certain equipment the relevant requirements of EN 60950-1:2001 + A11 and IEC 60950-1:2001 shall be maintained. 3) The creepage distances, clearances and thickness of insulation between unearthed hazardous voltage input and hazardous voltage output circuits have complied with basic insulation requirements according to EN 60950-1:2001 + A11 and IEC 60950-1:2001. 4) The output ratings as shown on the label must not be exceeded. 5) The equipment is to be supplied from a DC source which is separated from AC mains by double or reinforced insulation, or by basic insulation and suitable earthing providing equivalent protection. 6) The equipment is intended to be installed into a class I or class II system, when installed into class I system, protective earth has to be reliably identified and suitable external protection devices have to be provided in the final system. 7) The equipment shall be installed with an external forced air-cooling according to installation instruction accompanied with the unit. The airflow direction is towards the side of the equipment. RoHS Compliance Complies with the European Directive 2002/95/EC, calling for the elimination of lead and other hazardous substances from electronic products. (c)2008 Bel Fuse Inc.
