WARNING!
In areas at risk from explosion:
– Note the details of the type examination certificate
PTB 00 ATEX 2048 X for the Namur sensor
NJ1.5-8GM-N.
CAUTION!
Danger from unnoticed bearing damage
If the pump is intended for operation with diagnostic
equipment for bearing damage (e.g. for areas area at
risk from explosion), then it also has to be electrically
installed.
– Electrically connect the diagnostic equipment for
bearing damage to a suitable monitoring device.
CAUTION!
The pump's earthing concept is not suitable for active
cathodic corrosion protection with external current.
Wire the earthing lines of all electrical components for the supplied
installation cleanly and permanently to an electrically clean
earthing point, e.g. with an earthing bar on site - see earthing dia‐
grams in the appendix.
Connect the partial potential equalisation points of the pump, motor
and, if necessary further units, which are not connected electrically
cleanly to the pump, electrically cleanly via potential equalisation
lines - see dimensional drawing. Electrically wire an additional
potential equalisation cable from the potential equalisation cables
from this system cleanly and permanently to an electrically clean
potential equalisation point, e.g. to a potential equalisation bar on
site.
Install the other units in line with their documentation.
