Note
This hand shows that there are Notes to give you helpful hints for operating the conveyor belts.
Make sure that all persons working with or at this machine also read the following safety instructions attentively and
observe them.
These operating instructions only apply to the machine types mentioned on the title sheet.
The instructions must always be available in the place of operation of the conveyor belt.
When using the conveyor belt in moist or wet surroundings (humid area), one must make sure that the required type of
protection is met.
Note
For full information about the entire range of control boxes, please refer to “Control Boxes” in the operating
instructions.
The initial start-up, conversion, maintenance and repair work may only be carried out by qualified and authorised staff
(see also “Requirements for the User” in this chapter).
During assembly, maintenance and repair work, the conveyor belt has to be all-pole disconnected from the mains in
accordance with the Association of German Electrotechnical Engineers (VDE).
Work on electrical equipment may only be carried out by a specialist electrician or by a person instructed in electro-
technics under the supervision of a specialist electrician according to the electrotechnical regulations.
Attention
There is the risk of injury and danger through electric shock!
•Users and operators must take care that only authorised staff works at the conveyor belt.
•Changes that restrict safety must be reported to the operator immediately.
•The conveyor belt may only be operated if it is in perfect condition.
•The conveyor belt may only be operated in the sense of its intended use.
•Please observe the safety regulation VBG 10 for continuous conveyors and VBG 4 for electrical equipment and op-
erating material.
•Make sure that the protective earthing of the power supply is in perfect condition.
•It is absolutely forbidden to operate the conveyor belt without its casing and protective covers (chain drive).
•The gap at the drawing-in points of the belt may not be wider than 4 mm, otherwise there is a drawing-in hazard.
Should the gap become wider after adjusting the belt, the protective collar also has to be readjusted.
Intended use
The belt hopper is intended to be used for storing and transporting material to be conveyed.
This material must have a smallest lateral length of at least 5 mm.
Caution
Smaller parts may get under the belt, causing damage or failure to the conveyor belt.
With standard belts, the material to be conveyed has to be dry, clean and not have sharp edges. For the transport of
sharp-edged, oily, wet or hot (> 70°C) material, special belts have to be used.
The material to be conveyed must not fall onto the conveyor belt from a greater height. The maximum permissible im-
pact energy is 0.1 J.
In case of doubt, please ask the manufacturer.

Rhein-Nadel Automation GmbH 7
VT-MA-BUW-GB_2017.doc / 31.03.2017 SD
The hopper belts are designed for horizontal transport with maximum load. A slight inclination of the conveying level is
possible in particular cases. In such a particular case, please ask the manufacturer what is possible.
Please refer to Technical Data (Chapter 1) for the permissible belt loading.
Noise emission
The continuous sound level is maximum 70 dB(A). The transport of material or the quality of the belt can produce a
higher noise level. For these exceptions, you can ask your manufacturer about noise abatement measures.
Requirements for the user
Initial start-up, conversion work as well as maintenance and repair work may only be carried out by qualified and au-
thorised staff.
We differentiate between four levels of qualification:
Qualified staff
Qualified staff are persons acquainted with the installation, assembly, initial start-up and operation of the conveyor belt.
They have an adequate qualification for their job.
Authorised staff
is qualified staff that has been made familiar with a clearly defined duty by the operator of the conveyor belt.
Specialist electricians
(according to IEC 364 and DIN VDE 0105 Part 1) are persons who, thanks to their training in the subject, specialist
knowledge and technical experience of the relevant norms, are able to assess the tasks they have been entrusted with
and recognise any possible hazards.
Electrotechnically instructed person
(according to IEC 364 and DIN VDE 0105 Part 1) is someone who has been instructed by a specialist electrician in the
tasks entrusted to him/her. This person has also been informed about the possible dangers that can occur through in-
appropriate behaviour and about the necessary protective gear and precautionary measures.
2.1. Applicable Directives and Standards
The hopper has been built in accordance with the following directives:
•EC Directive “Machinery” 2006/42/EC
•EC Low Voltage Directive 2014/35/EU

3. Construction and function of the belt hoppers
The basis of the belt hoppers is the RNA conveyor belt FP120, the body of which consists of a special aluminium
groove profile. For the drive, one can choose motors of the 3-phase or AC type. They are direct drives that can be
mounted either on the left or right at the beginning of the belt, as desired.
The mountings like bulk hopper, seals, discharge chute and seal curtain are made of 1.4301 – brushed on the outside
– and assembled at the works. Depending on the type of motor, the belt hopper is either controlled by protective motor
switches, electronic control units or frequency-controlled control units.
Note
For information about the control units, please refer to “Control units” in the separate operating instructions.
Picture 1: Construction of the belt hopper
4. Transport and assembly
4.1. Transport
Transport ex works
The belt hoppers are delivered ex works packed either in a carton or box.
Internal transport
The weight of the belt hopper depends on the measurements and motor rating. You will find the weight of your special
model in the transport documents.
Attention
When unpacking, control all the safety devices. Replace damaged parts before initial start-up.
Caution
One-piece conveyor belts can be brought to their place of use on a sufficiently stable haulage car.
