Other important considerations for dosing pumps in ex-zones
9.1
Application in accordance with regulations
•
In areas of operation where there is a risk of explosion, the pump may only be operated with
the appropriate nameplate and the corresponding EU declaration of conformity for areas of
operation where there is a risk of explosion in accordance with directive 94/9/EU concordant
with the European directives. The explosion group, category and protection system stated
on the label must be equivalent to or better than the conditions specified in the designated
area of application.
•
Any other application or modification is prohibited!
•
Pumps which do not have the appropriate nameplate and the corresponding EU declaration
of conformity for areas of operation where there is a risk of explosion may under no
circumstances be operated in areas of operation where there is a risk of explosion.
9.2
Safety instructions
WARNING
•
When installing and operating equipment in ex-zones in Europe, you must observe the
European directive 99/92/EU (ATEX 137). In Germany this is incorporated within the
occupational safety regulations and German regulations on hazardous materials.
•
You must observe the European standards EN 1127-1, EN 60079-10, EN 60079-14, EN
60079-17 as well as EN 50020 and EN 50039 for intrinsically safe electrical circuits. (In
Germany, these standards are partly covered by VDE 0165 and VDE 0118.)
•
For countries outside the EU, you should observe the appropriate national directives.
•
Installations in ex-zones must be checked by a "recognised qualified" person. This
particularly applies to intrinsically safe electrical circuits.
•
The information detailed below chiefly refers to particular features found in ex-zones. It does
not replace the standard information in the operating instructions manual!
•
When cleaning plastic components, you should ensure that no electrostatic charge is
created through excessive friction. - see warning sign
9.2.1 Safety equipment
WARNING
•
Please adhere to the following safety instructions for pumps containing non-
conductive components.
ATTENTION
Because of electrostatical flammable
danger, use damp cloth only to wipe
off plastic parts !
9.2.2 EU declaration of conformity / certification
The EU declaration of conformity is attached for the whole pump (also for pumps without
motors).
The EU declarations of conformity, EU design inspection reports and the operating instructions
manuals for the individual components are attached.
9.3
Assemble
No specific notes.
