Intrinsic Safety Information
• Do not connect to the DataTrac PC interface port whilst in a hazardous location.
• The maximum input voltage, Um, at the DataTrac PC interface port is 6V. The safe area appratus that is to be
connected to the DataTrac PC Interface port must be a Safety Extra Low Voltage (SELV) or Protective Extra Low
Voltage (PELV) circuit, e.g. the serial (RS232) interface or USB interface of a PC.
• Do not charge the battery pack whilst in a hazardous location.
• Do not disconnect the battery pack from the pump whilst in a hazardous location. Fit the battery pack to the
pump only when in a clean, dust free environment.
• Use only SKC approved chargers designated for this pump model.
• Do not subject the equipment to intense sunlight for long periods.
• The equipment has not been assessed as a safety related device (as referred to in Directive 94/9/EC Annex II,
clause 1.5).
• The recessed LCD screen window could potentially store an electrostatic charge if rubbed. Precautions must be
taken to prevent the build up of electrostatic charge, particularly if the pump is used in a zone 0 location. Clean
the LCD screen window only with a damp cloth.
• The equipment should not be used if damaged in a way that could invalidate intrinsic safety. Such defects might
include cracking of the pump or battery pack enclosure and internal encapsulant such that internal components
or cells are exposed.
• Substitution of components with non-SKC approved components may invalidate the intrinsic safety certification
of the pump.
Important note about intrinsic safety
If you are unsure as to whether the air sampling pump you have purchased is suitable for your environment, check with
your site manager or responsible person BEFORE USE that the intrinsic safety rating on the product meets your site
requirements. SKC personnel are unable to recommend the appropriate safety rating for your site.
