Weighing platforms of the series ISI 150IGG-H… and IS300IGG-H comply

with the European Standards EN 50 021: 1999 and EN 5028-1-1-1

according to the Statement of Conformity, No. TüV 01 ATEX 1739 X,

including the 1

and 2

Supplements (see “TÜV Certificates”). Therefore, they

are suitable for use in Zones 2 and 22 hazardous areas. Their approval

marking is:

The type of explosion protection used in these weighing platforms involves

protection of the housing against penetration of potentially explosive vapor. For

this purpose, IP67 protection of the platform must be ensured when it is

connected to the power source. Opening the platform or disconnecting cables

while the scale is plugged into the power supply is strictly forbidden. Please

read the installation instructions in the Annex 35751-000-16-A4. To install the

power supply, please follow the installation instructions given in the section

entitled “Connecting the Weighing Platform” in “Getting Started.”

If you will be operating the platform outside the European Community in a

Zone 2 hazardous area, you must comply with the national electrical code and

applicable safety regulations of your country. Please ask your local Sartorius

service technician, office or dealer for information on the currently valid

regulations applicable in your country.

The weighing platform may not be operated in Zone 0, 1, 20 or 21 hazardous

areas, as it does not have an EX approval certificate for these areas.

Any tampering with the weighing platform by anyone, other than installation of

preload devices, will result in forfeiture of all claims under the manufacturer's

warranty.
