Contamination Requirement
Notes:
1. ANSI/ISA-S71.04. 1985. Environmental conditions for process measurement and control systems: Airborne contaminants, Instrument Society of America,
Research Triangle Park, NC, 1985.
2. The derivation of the equivalence between the rate of copper corrosion product thickness growth in Å/month and the rate of weight gain assumes that Cu2S and
Cu2O grow in equal proportions.
3. The derivation of the equivalence between the rate of silver corrosion product thickness growth in Å/month and the rate of weight gain assumes that Ag2S is the
only corrosion product.
4. The deliquescent relative humidity of particulate contamination is the relative humidity at which the dust absorbs enough water to become wet and promote ionic
conduction.
5. Surface debris is randomly collected from 10 areas of the data center on a 1.5-cm diameter disk of sticky electrically conductive tape on a metal stub. If
examination of the sticky tape in a scanning electron microscope reveals no zinc whiskers, the data center is considered free of zinc whiskers.
Acoustical specifications
The library meets the acoustical requirements for general business area category 2D. Category 2D states that the library can be installed a minimum of 4 m (13 ft.) from a
permanent work station.

Maximum acoustical noise sound power level LwAD in Bels (1 Bel = 10 dB) 6.8
Power cords and receptacles
Electrical and safety information, and feature codes for purchasing power cords.
To avoid electrical shock, a power cord with a grounded attachment plug is provided. Use only properly grounded outlets.
Table 1 lists the power cord part number, feature code, the country, or region where the power cord is used, and the plug's standard reference. The
last column in the table contains an index number that you can match to a specific receptacle type in Figure 1.
All power cords use an appliance coupler that complies with the International Electrotechnical Commission (IEC) Standard 320, Sheet C13.
If the power cord that you receive does not match your receptacle, contact your local dealer.
Power cords that are used in the United States and Canada are listed by Underwriter's Laboratories (UL), are certified by the Canadian Standards
Association (CSA), and comply with the plug standards of the National Electrical Manufacturers Association (NEMA). For other worldwide geographies,
plug standards are listed in Table 1.
Figure 1 shows the receptacles that are used by the power cords in Table 1. Match the index number that is beside each plug to the index number in the table.
