1 - General safety information
This chapter provides information about handling, installation and maintenance of the gear reducers and
gearmotors applied in potentially explosive environments ATEX).
All the people handling with these activities must carefully read all the following instructions and
apply them rigorously.
The information and the data contained in this document correspond to the technical level reached at
the moment the handbook is printed. Rossi reserves the right to introduce, without notice, the necessary
changes for the increase of product performances.
1.1 - Residual risks
The equipment has been designed and manufactured according to state-of-the-art technology as per
standards contained in "EU Declaration of conformity".
The application of such standards has allowed to reduce the intrinsic risks of the equipment type at an
acceptable level.
Therefore, here following you will find the residual risks list the user will have to consider.
If the instructions and specific selection, installation, verification and maintenance instructions are not
followed in zones with danger of explosion, the residual risk of causing an explosion would consequently
increase.
1.2 - Recycling
Observe the established legislation concerning waste treatment and recycling of exhaust material:
– housings, gears, shafts and bearings of gear reducer must be handled as scrap iron materials, along with
all other steel components;
– worm gears have a bronze crown and must be handled as bronze waste material, along with other bronze
components;
– for all other non-metallic components (seal rings, caps, etc.) follow the instructions in force;
– exhausted oils must be collected and handled as required by established legislation.
1.3 - Safety
The paragraphs marked with symbols shown below contain recommendations to be strictly respected
in order to assure personal safety and to avoid any heavy damages to the machine or to the system (e.g.:
works on live parts, on lifting machines, etc.).
Electric or mechanical danger, e.g.:
– live parts;
– temperature higher than 50 °C;
– presence of rotating pieces during the running;
– suspended loads (lifting and handling);
– eventual high sound level ( > 85 dB(A));
Safety instructions for the use in areas classified according to ATEX 2014/34/EC.
IMPORTANT: gear reducers and gearmotors supplied by Rossi are components and must be incorporated
into machinery and should not be commissioned before the machinery in which the coponents have
been incorporated conforms to:
−Machinery directive 2006/42/EC and subsequent updatings; in particular, possible safety guards
for shaft ends not being used and for eventually accessible fan cover passages (or other) are the
Buyer's responsibility;
−«Electromagnetic compatibility (EMC)» 2014/30/EC and subsequent updatings.
Attention! It is recommended to pay attention to all instructions of present handbook, all existing
safety laws and standards concerning correct installation.
Whenever personal injury or property damage may occur, foresee adequate supplementary protection
devices against:
−release or breakage of fastening screws;

5
UTD.123.2019-10.00_EN
−rotation or loosening of the gear reducer from shaft end of driven machine following to accidental
breakage of the reaction arrangement;
−the accidental breakage of shaft end of driven machine.
If deviations from normal operation occur (temperature increase, unusual noise, etc) immediately
switch off the machine.
Installation
An incorrect installation, an improper use, the removing or disconnection of protection devices, the lack
of inspections and maintenance, improper connections may cause severe personal injury or property
damage. Therefore, the products must be moved, installed, commissioned, handled, controlled, serviced
and repaired exclusively by responsible qualified personnel.
In the case of installation in places where there may be the formation of stray currents (eg: near electric
railway networks, large welding plants, electrical installations with high currents and radio frequencies,
etc.), it is appropriate to take adequate precautions to avoid consequences.
The skilled personnel must be specifically instructed and have the necessary experience to recognize
any risks connected with present products avoiding any possible emergencies.
In this regard, see the standard IEC / EN 60079-14 "Explosive atmospheres - Part 14: Design, selection
and installation of electrical systems", in particular Annex F "knowledge, skills and competences of the
responsible persons, of the operational and of the designers.
Gear reducers and gearmotors of present handbook are normally suitable for installations in industrial
areas: additional protection measures, if necessary, must be adopted and assured by the personnel
responsible for the installation.
Attention! Motors in non-standard design or with constructive variations may differ in the details from the
ones described here following and may require additional information.
Attention! For the installation use and maintenance of the electric motor (standard, brake or non-standard
motor) or of the possible motor-variator and/or the electric supply device (frequency converter, soft-start,
etc.), and/or any optional electric devices (e.g.: independent cooling unit, etc.), consult the specific attached
documentation. If necessary, require it.
Maintenance
When operating on gear reducer or on components connected to it the machine must be at rest: disconnect
motor (including auxiliary equipments) from power supply, gear reducer from load, be sure that safety
systems are on against any accidental starting and, if necessary, pre-arrange mechanical locking devices
(to be removed before commissioning).
Attention! During the running the gear reducers could have hot surfaces; Always wait that the gear
reducer or the gearmotor to cool before carrying out any operations.
ATEX requirements
For whatever operation (assembling, disassembling, cleanness, maintenance) use tools and procedures
which will not cause explosion (e.g.: sparks). When using electric equipment (portable working lights,
vacuum cleaner, etc.) be sure that they are cer tified according to ATEX directive and suitable to the area.
Whenever the gear reducer/gearmotor is disassembled, moved and mounted to another installation, or
modified, e.g. with the application of a different motor (see table 7.1), check whether it is compatible
with the new installation and classification of the area, as well as its suitability for the envisaged
service as indicated by the service specifications (fs, radial loads, ch. 7.15), thermal power Pt (ch. 7.16),
radial loads, etc.).
When a bearing lubrication pump is present in G gear reducers ("P" code stated on name plate, see DESIGN)
it is necessary to avoid input speeds lower than n1= 355 min-1, consult us if need may be.
This handbook «ATEX operating instructions» and its enclosures, if any, must be kept close to the
gear reducer or gearmotor in order to be easily consulted.
Further technical documentation (e.g. catalogs) can be downloaded from our website www.rossi.com or can
be directly required to Rossi. For any clarification and/or additional information consult Rossi and specify
all name plate data.

4.1 - General
Every gear reducer is provided with a name plate in anodised aluminium containing main technical information
relevant to operating and constructive specifications and defining, according to contractual agreements (see
fig. ,below), the application limits; the name plate must not be removed and must be kept integral and readable.
All name plate data must be specified on eventual spare part orders.
Attention! For the mass stated on name plate remind that:
– it does not consider the lubricant mass;
– it is the maximum one for the gear reducer size, therefore the actual one can be lower as it depends from train
of gears and transmission ratio;
– for the gearmotors the mass is always the same of gearmotor without motor, therefore consider also the mass
of motor stated on relevant name plate in order to know the total mass.
In view of above mentioned points, if it is necessary to know the exact mass, consult Rossi.
Gear reducers and gearmotors are mechanical devices including one or more gear pairs (with internal or external
toothing) with several space positions (parallel, intersecting, orthogonal axis), with the aim to reduce motion and
to increase torque of a rotating driving machine (e.g. electric, hydraulic motor, etc.) to drive a great number of
machines (lifting, traverse movements, rotations, etc.).
They are made of a cast iron or stainless steel housing, including shafts equipped with toothed gear wheels
and supported by taper roller bearings; the gear pairs and bearings are grease or oil lubricated with different
lubrication solutions: bath, splash or ducts lubrication; gear reducers and gearmotors are equipped with at least
one input (high speed) shaft and one output (low speed) shaft; the lubricant is kept inside the hoousing through
elastomer-based sliding seals.
