3. Safety
3.1 General safety instructions
WARNING
Electric shock
Death or serious personal injury
‐Before starting any work on mixers or
flowmakers, disconnect the motor from
the supply or make sure that the fuses
have been removed or the main switch
has been switched off. Make sure that
the power supply cannot be switched
on unintentionally.
WARNING
Crushing hazard
Death or serious personal injury
‐Make sure that all rotating parts have
stopped moving.
Follow the installation and operating in-
structions of this manual when transport-
ing, storing, handling and operating the

out by qualified persons.
Make sure that persons cannot accidental-
ly fall into the tank.
3.2 Explosion-proof products
When using explosion-proof mixers and
flowmakers, observe the following safety
regulations.
Equipotential bonding
All explosion-proof mixers and flowmakers have an
external equipotential bonding terminal on the back of
the motor. A copper wire with a minimum cross
section of 4 mm2 can be connected to this terminal.
The power cable must be fixed,so it cannot be caught
in the propeller during operation.
Leakage sensor
With the Grundfos ALR-20/A-Ex relay, the leakage
sensor forms the basis of the Ex protection. The relay
must always be installed with explosion-proof mixers
and flowmakers. The relay must be ordered
separately.
Part number: 99794613 or 96489569.
As the leakage sensor is intrinsically safe, it must be
connected through the blue leads.
9
English (GB)

Temperature monitoring
The motor temperature must always be monitored
through the built-in PTC sensors. The associated
relay must be certified for this use with the safety
level, SIL 1. If the relay is built in as part of a
frequency converter, the converter must also fulfill SIL
1.
Power supply cable
The factory-fitted power supply cable must not be
shortened.
Mixers and flowmakers must not be dis-
mantled in an explosive atmosphere.
Soft starter and frequency converter
Soft starters and frequency converters may only be
used if their Ex classification is higher than the
classification of the mixer or flowmaker, and if they
are installed in accordance with the Ex regulations.
Accessories
Use the mixer or flowmaker only with original and
approved accessories.
Flowmakers
Due to the risk of electrostatic charging, flowmakers
with polymer propeller must always be submerged in
water, if the environment is explosive.
Maintenance, service and repair
Dismantling of mixers, flowmakers or their
cable entries must be carried out by
Grundfos or an authorised service work-
shop.
Use only original and approved compo-
nents.
For inspection and maintenance the standard EN
60079-17 must be considered and fulfilled.

5.3.7 Mounting the propeller blades of AFG.xx.150
The propeller blades are fixed in position
using the pressure of the clamping jaws
which are tightened by screws (3). The
function of the set screw (2) is to position
the blade in the right angle before tighten-
ing the clamping jaws.
The blade can be fitted in three different angles.
Choose the angle according to the required stirring
power and liquid density. When in doubt, use the
middle position.
The propeller blades must be mounted in
the same position. Otherwise, the propeller
and installation has an uneven loaded.
