11.0 Electrical/Environmental Requirements
11.1 Electrical (Supply voltage fluctuations not to /- 10%)
NU-813-300/400/600 115Vac, 60Hz, 1 Phase, 5 Amps
NU-813-300E/400E/600E 230Vac, 50/60Hz, 1 Phase, 3 Amps
11.2 Operational Performance (for indoor use only)
Environment Temperature Range: 41 ° F-104 ° F (5 ° C - 40 ° C)
Environment Humidity: Maximum relative humidity 80% for temperatures up to 31 ° C
Decreasing linearly to 50% relative humidity at 40 ° C
Environment Altitude: 6562 Feet (2000 Meters) Maximum
11.3 Light Exposure
Standard Fluorescent Lighting @ 150 ft. candles (1614 LUX) maximum intensity.
11.4 Installation Category: II
Installation category (overvoltage category) defines the level of transient overvoltage which the instrument is designed to
withstand safely. It depends on the nature of the electricity supply and its overvoltage protection means. For example,
in CAT II, which is the category used for instruments in installations supplied from a supply comparable to public mains
such as hospital and research laboratories and most industrial laboratories, the expected transient overvoltage is 2500 V
for a 230 V supply and 1500 V for a 120 V supply.
11.5 Pollution Degree: 2.0
Pollution degree describes the amount of conductive pollution present in the operating environment. Pollution degree 2
assumes that normally only non-conductive pollution such as dust occurs with the exception of occasional conductivity
caused by condensation.
11.6 Chemical Exposure
Chemical exposure should be limited to antibacterial materials used for cleaning and disinfecting. CHLORINATED AND
HALOGEN MATERIALS ARE NOT RECOMMENDED FOR USE ON STAINLESS STEEL SURFACES. Equipment
decontamination can be accomplished by non-condensing gas or vapor paraformaldehyde, Hydrogen Peroxide or
Chlorine Dioxide following NSF/ANSI Annex G.
11.7 EMC Performance (classified for light industrial)
Emissions: EN61326
Immunity: EN61326
Class A equipment is intended for use in an industrial environment.
In the documentation for the user, a statement shall be included drawing
attention to the fact that there may be potential difficulties in ensuring
electromagnetic compatibility in other environments, due to conducted as
well as radiated disturbances.
Note: The EMC performance requirements are generated within the product enclosure.
The enclosure will be all metal grounded to earth.
In addition, the membrane front panel will also include a ground plane for maximum protection
and an electrostatic shield.
