5.9 Specialities for types built in compliance with the provision 2014/34/EU (ATEX)
The multi-outlet pump unit was designed for an ambient temperature range of
-20 ... +80 °C.
Install the multi-outlet pump unit apart from directly adjacent electrical equipment.
(EN1127-1 sections 5.3.5 … 5.3.9)
The multi-outlet pump unit and all the metallic as well as electrically insulated
attachments have to be integrated into the existing potential equalization system.
Pipes and connected components have to be grounded.
Static charges on parts made from synthetic material and cables have to be ex-
cluded.
For cleaning surfaces of parts made from synthetic material use wet cloth only.
When, within the equipment, separating a potential equalization or a part with poten-
tial equalization from a metallic component, for example, during repair work, then a
connecting line of appropriate cross-section has to be installed for bridging, when an
electrically conducting connection was interrupted.
As for cleaning and maintenance intervention, make sure that no inflammable sparks
can be generated by friction and shock.
Replace corroded components.
Consider the operating manuals of attachments, in particular the ones of electrical
components.
As for drives, which do not meet the stipulations of the operating manual, the user
shall carry out an ignition hazard assessment.
Motor-based drives with valid EC-prototype examination are allowed to be incorpo-
rated only.
The drive power must not exceed 0,37 kW.
In case of failure and/or faults, get the pump unit checked and repaired by competent
personnel or WOERNER themselves.
Dismantle the pump unit and handle the single parts exclusively outside of poten-
tially explosive areas.
