`

X see manual

For equipment labelled with „

`

X see manual“ the following classifica-

tion according to Directive 94/9/EC (ATEX) is valid:

`

II 3G IIC T3 X,

Internal Atm. only, Tech. File Ref.: VAC-EX01.

The classification II 3G IIC T3 X according to ATEX is only valid for the in-

ner part (wetted part, pumped gas or vapor) of the equipment. The equip-

ment is not suitable for use in external, potentially explosive atmospheres

(environment).

The overall category of the equipment depends on the connected com-

ponents. If the connected components do not comply with the classifi-

cation of the VACUUBRAND equipment, the specified category of the

VACUUBRAND equipment is no longer valid.

Vacuum pumps and vacuum gauges in category 3 are intended for con-

nection to equipment in which during normal operation explosive atmo-

spheres caused by gases, vapors or mists normally don’t occur; or, if they

do occur, are likely to do so only infrequently and for a short period only.

Equipment in this category ensures the requisite level of protection dur-

ing normal operation.

The use of gas ballast or the operation of venting valves is only permit-

ted if thereby explosive atmospheres normally don’t occur in the interior

of the equipment or, if they do occur, are likely to do so only infrequently

and for a short period.
