Figure 16 – All-plastic terminal box on the casing
Open the terminal box only in a de-energized state.
Connection to the terminals is carried out according to
the description on the electric motor cables in the termi-
nal box or according to the description of the terminals or
according to the picture on the terminal box cover.
Cables approved for this purpose must be used to co-
nnect the fan's electric motor. See Table 6 for a detailed list
of recommended cables. The fan must be properly groun-
ded.
After starting, it is necessary to check the correct direc-
tion of rotation. The direction of rotation of the mounted
fan impeller can be checked by removing the rubber plug of
the inspection hole on the fan bowl, see Figure 17.
Figure 17
After starting the fan, it is necessary to measure the cu-
rrent, which must not exceed the maximum permitted cu-
rrent indicated on the production label ( I
values are higher, check the regulation of the pipe network.
The fan is started after being mounted on the pipe ne-
twork for which it is designed, or choked with closed suc-
tion or discharge so as not to overload the fan!
Attention! The fan is loaded by increasing the flow rate,
i.e. by releasing the throttle.
The installation must comply with the regulations
according to the standard ČSN EN 60079-14 Explosive at-
mospheres - Part 14: Design, selection and establishment
of electrical installations. When designing the installation,
take into account the requirements arising from the Fire
Safety Solution report and the report on the determination
of external influences.

RP Ex fans are not intended for direct sale to consu-
mers or to users. They are sold exclusively in commerci-
al relations to professional assembly companies.
RP Ex fans are manufactured in accordance with valid
Czech and European regulations and European standards.
RP Ex fans must be installed and used only in accordance
with this documentation. Other uses do not correspond to
the intended purpose.
The manufacturer is not responsible for damages
caused by other use and all risks are borne by the user. In-
stallation and operating documentation must be accessible
to operators and service personnel and it is advisable to
place it near the installation. During handling, assembly,
electrical connection, commissioning, as well as repairs and
maintenance of the device, it is necessary to respect the
applicable safety regulations, standards and generally reco-
gnized technical rules.
In particular, it is necessary to use personal protecti-
ve work equipment (gloves) during any manipulation,
assembly, disassembly, repair or inspection due to the
presence of sharp edges and corners.
All equipment connections must comply with relevant
safety standards and regulations.
Changes and modifications that could affect safety are
prohibited. During operation, it is necessary to ensure the
safe and environmentally friendly disposal of all exchangea-
ble parts, operating and auxiliary materials. When disposing
of materials, it is necessary to comply with the relevant
environmental and waste disposal regulations. In the case
of final disposal, it is necessary to proceed according to the
principles of differentiated collection. We recommend han-
ding over metal parts to metal waste collection centers for
scrapping, dispose of other parts according to the rules of
separate collection.
Familiarize yourself before installation and use
and respect the following instructions and recommendati-
ons.
