CE Compliance
The unit has been designed and tested to comply with directive 73/23/EEC and its subsequent
amendments by the European Community (EC or CE). The directive relates to electrical
equipment designed for use within certain voltage limits. It ensures that electrical equipment is
constructed with good engineering practice in safety matters.
The unit has been designed and tested to comply with directive 89/336/EEC and its subsequent
amendments. The directive relates to electromagnetic compatibility. It demands that
electromagnetic disturbance does not exceed a prescribed level; that the equipment be immune
to a prescribed level of ambient level of interference; that the equipment be protected against
electrostatic discharges; and that the equipment be immune to all electrical shock wave
disturbances. As of 1997, measures have been added to test for fire hazard, electric shock
hazard, and also external exposure to other forms of energy.
The requirements specified by directive 89/336/EEC are as follows. CE compliance requires
that the manufacturer or its authorized representative established within the Community affix the
EC conformity mark to the apparatus or else to the packaging, instructions for use, or guarantee
certificate. The EC conformity mark shall consist of the letters CE as specified and the figures of
the year in which the mark was affixed. This mark should, where appropriate, be accompanied
by the distinctive letters used by the notified body issuing the EC type-examination certificate.
Where the apparatus is the subject of other Directives providing for the EC conformity mark, the
affixing of the EC mark shall also indicate conformity with the relevant requirements of those
other Directives.
CSA / IEC Compliance
The unit complies with certain standards of the Canadian Standards Association (CSA) and the
International Electrotechnical Commission (IEC).
The unit is in Installation Category (Overvoltage Category) II under IEC 664. IEC 664 relates to
impulse voltage levels and insulation coordination. The particular category is defined as: local
level, appliances, portable equipment, etc, with smaller transient overvoltages than Installation
Category (Overvoltage Category) III.
The unit is in the Pollution Degree 2 category under IEC 1010-1 and CAN/CSA-C22.2 No.
1010.1. The IEC standard on Safety Requirements for Electrical Equipment for Measurement,
Control, and Laboratory Use relates to insulation coordination. The CSA standard is on Safety
Requirements for Electrical Equipment for Measurement Control, and Laboratory Use, Part I:
General Requirements. The Pollution Degree 2 category is defined as follows: “Normally only
non-conductive pollution occurs. Occasionally, however, a temporary conductivity caused by
condensation must be expected.”
UL
The unit complies with Underwriters Laboratories (UL) standard 1950, the Standard for Safety
Information Technology Equipment.
