the EnVision technical information.
Safety standards
Certification:
• IEC-CB, CE and NRTL-TUV Rheinland of North America
The instrument fulfills the requirements of:
• IEC 61010-1:1990 + A1(1992) + A2(1995)
• CAN/CSA-C22.2 No. 1010.1 – 92 + A2:97
• UL 61010A-1: 2002 R4.02
Class 1 Laser product
Caution! Use of this instrument other than specified in the user instructions
may result in exposure to hazardous laser radiation.
The laser is classified according to standard EN 60825-1 + A1.2002 +
A2:2001 (IEC 60825-1 Ed. 1.2, 2001-08)
The safety specifications are met also under the following environmental
conditions in addition or in excess to those stated in the operating
conditions:
Altitude: up to 2000 m
Temperature: +5°C to +40°C
Relative humidity: Maximum 80% at 31°C decreasing linearly to 50% at
40°C
Mains supply fluctuations: ±10%
Installation category (overvoltage category): II according to IEC 664-1
(Note 1)
Pollution degree: 2 according to IEC 664-1 (Note 2)
Note! 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 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.
