6 Installation of Associated
Components
Beforeinstallingthepump,alwayschecktheidentica-
tion plate of the pump.
TheATEXclassicationmustcorrespondwiththeconditions
oftheworkingenvironment.
6.1 Installing the Motor
1. Make sure the motor is suitable for use in a potentially
explosiveenvironment.
2. Make sure that the motor is properly connected to the
power supply. Refer to the motor manual for the appropri-
ate instructions.
Earth connection
u The power supply must include an earth connection.
6.2 Installing the Gearbox
1. Makesurethegearboxissuitableforuseinapotentially
explosiveenvironment.
2. Refer to the documentation of the gearbox for specic
productinformationaboutoperatinginapotentiallyexplo-
sive environment.
6.3 Hose Burst Detection Kit
It is essential to use ATEX rated hose burst detection sen-
sors to detect a potentially dangerous situation in time.
Use similar of higher ATEX rated devices with pump
uOnly use sensors that are approved by ATEX standards!
Theclassicationshouldbesimilarorhigherthanthatof
the pump.
6.4 Non-Standard Pump Orientations
There may be cases where the lubricant level cannot be
visually monitored through the inspection window such as
whenthepumpisttedwithmetalinspectionwindows.
In these cases the customer should ensure that the pumps
are installed with appropriated ATEX rated hose burst de-
tectionkitforadditionalprotection(grefer to section 6.3).
6.5 Grounding the Pump
The pump should be grounded before operation. This can
be done either through motor earth wiring or alternately by
grounding through the base frame.
