3.3 Ex certification and classification

SRP pumps designed for application in potentially explosive 
environments (Ex versions) are supplied with a nameplate with 
certification details. 
Figure 3 shows the nameplate of an explosion-proof SRP pump.

4. Safety

4.1 General safety instructions

4.2 Explosion-proof versions

Equipotential bonding

Explosion-proof SRP pumps must be earthed by means of a 
copper cable of min. 4 mm² via the equipotential bonding terminals 
on the back of the motors.
The cable must be fixed in such a way that it cannot be caught in 
the impeller during operation.

Leak sensor

Together with the Grundfos relay, type ALR-20/A Ex, the leak 
sensor forms the basis of the Ex approval. The relay must 
therefore always be installed together with explosion-proof SRP 
pumps. The relay must be ordered separately.
Product number: 96489569.
As the leak sensor is intrinsically safe, it must be connected via 
the blue conductors.

Temperature monitoring

The motor temperature must always be monitored via the built-in 
PTC sensors. The associated relay must be certified for this use.

Supply cable

The factory-fitted supply cable must not be shortened.

Frequency converter

The pump is designed for frequency converter operation in the 
30 to 50 Hz range. Danfoss frequency converters, type FC300, 
can be used. For further information about size and parameter 
settings, contact Grundfos.
Frequency converters may only be used if the Ex classification of 
these are higher then for the recirculation pumps, and if they are 
installed in accordance with the Ex regulations.

Accessories

SRP pumps must only be used together with accessories 
supplied and approved by Grundfos.

Warning

Before starting work on the product, make sure 
that the fuses have been removed or the mains 
switch has been switched off. Make sure that the 
power supply cannot be accidentally switched 
on.

Warning

These safety instructions as well as the 
instructions in each individual section must be 
followed when transporting, storing, handling 
and operating the pump.

The pump must be installed, connected, started 
up and serviced by qualified persons.

Beware of rotating parts.

Make sure that persons cannot accidentally fall 
into the tank, e.g. by installing a cover or railing.

Warning

When using explosion-proof pumps, the 
following safety regulations must also be 
observed.
