9.4 Safety specifications
iEMS Incubator/Shaker HT fulfills the following requirements:
EN 61010-1:1993 + A2:1995/IEC 61010-1:1990 + A1:1992 + A2:1995 including CENELEC Common
Modifications, US and CA National differences
EN 61010-2-010:1994 + A1:1996 including CENELEC Common Modifications, US and CA National
differences
EN 61010-1:2001 (Ed. 2)
The safety specifications are also met under the following environmental conditions in
addition to or in excess of those stated in the operating conditions:
Altitude up to 2000 m
Temperature
+5 ° C – +40 ° C
Mains supply fluctuations ± 10% from nominal
Installation category
(overvoltage category) II according to IEC 60664-1 (see Note 1)
Pollution degree 2 according to IEC 60664-1 (see Note 2)
Note 1: The 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 means of
overvoltage protection. 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.
Note 2: The pollution degree describes the amount of conductive pollution
present in the operating environment. Pollution degree 2 assumes that
normally only nonconductive pollution, such as dust, occurs with the
exception of occasional conductivity caused by condensation.
Both of these affect the dimensioning of the electrical insulation within the
instrument.
