INSTALLATION INSTRUCTION
1) The DC-AC Converter can be operated at an ambient temperature up to 85°C maximum.
2) The DC-AC Converter is a built-in component. 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.
