O. Foreword
A geared motor proper is not subject to the Machinery Directive. Through appro-
priate installation and/or assembly in an overall system it becomes a component
of the machine or plant under construction, which must comply with the relevant
standards and directives. The manufacturer of the machine bears the sole res-
ponsibility for compliance with these standards.
1. Safety Instructions
A machine may not be taken into use until it has been ascertained that it meets
the protection and safety requirements of Machinery Directive 89/392/EEC and
its amending Directives 91/368/EEC and 93/44/EEC. The basic prerequisite
for correct installation and connection is knowledge of, and compliance with, the
operating and safety instructions, and the regulations relating to industrial safety
and accident prevention. Only qualified persons may be charged with work on
geared motors. Faults susceptible to projudice safety must be rectified immedia-
tely by previously appointed stoff.
Geared motors are devices for use in industrial machinery and
plant. In operation, these devices can have dangerous live, non-
insulated parts, or perhaps moving or rotating parts. Hence, for
example, unauthorised removal of the required casing, or impro-
per use, incorrect operatian or poor maintenance, could lead to
severe bodily harm or damage to machinery.
Persons responsicble for the safety of the machine or plant must the
refore ensure that:
– only qualified persons are charged with working on the machines or plant.
– such persons always have access to the current operating instructions and
other product documentation applicable to the work in hand, and that they
are charged with consistent compliance with these documents.
– unqualified persons are prohibited from working on or near the machines
or equipment.
Qualified Personnel are persons who by reason of their training, experien-
ce, instruction and their knowledge of the relevant standards, regulations, acci-
dent prevention rules and working conditions have been authorized by the per-
son responsible for the safety of the machine or plant to perform the appropria-
te activities required, and thereby are able to recognise and prevent potentially
dangerous situations (For the definition of skilled workers see VDE 0105 or IEC
364, which alsa regulate the prohibition of the employment of unqualified per-
sons). A knowledge of first aid and the local rescue organisation must also be
included.
It is assumed that the basic planning of the machine or plant and all operations
relating to its transportation, assembly, installation, commissioning, maintenance
and repair will be performed by qualified personnel or controlled by responsible
skilled hands. In this respect, special attention should be paid to:
– technical data, and information on permissible use which are included in the
catalogue, the documents relating to the order and on the data plate,
– the general regulations applicable to erection and safety,
– the local regulations and requirements specific to the machine or plant,
– the proper employment of tools, lifting and transport devices,
– the use of personal protective equipment,
– assembly conditions, to ensure the necessary protection for operators during
use, and to prevent personnel from approaching too closely for safety.
The present documentation would become too unwieldy if it contained all the
detailed information relative to possible construction variants, and it connot take
into account every conceivable case involving erection, operation or mainte-
nance. Consequently, it only contains the essential instructions necessary for qua-
lified personnel operating geared motors in industrial areas af application.
Should, in a special case where it is intended to use the machine or plant in non-
industrial areas of application, more stringent requirements have to be met (e.g.
to prevent children's fingers from touching the machine), these conditions must
be assured during assembly by introducing additional safety measures for the
machine or plant.
Changes from normal operation (increased power consumption, raised tempe-
ratures, vibrations, noises, etc. or indications from monitoring facilities) lead to
the assumption that the machine is not functioning correctly. To prevent faults
which, in their turn, might cause serious indirect or direct damage to persons or
machinery, the responsible maintenance staff must be informed immediately.
IN CASE OF DOUBT, SWITCH OFF THE MACHINE INVOLVED AT
ONCE!
2. Regulation Use
The geared motors are designed exclusively for installation in or for mating with
a machine or plant in industrial use. Use for any other or extended purpose is
non-regulation. The supplier will not be liable for any damage arising from this
improper use.
3. Erection
The beds on which the gears and geared motors are to be erected must be ade-
quately dimensioned and free from vibration. When mounting the geared motors
care must be taken to ensure that these are immovably mounted, free from distor-
tion, and on a level surface. Adequate ventilation for the motors must be assu-
red. Should coupling elements be fitted onto the drive- or output-shaft blows to
the shafts must be avoided since they could cause leakage or damage to the
bearings. Prior to fitting, the shaft-ends should be lightly greased to facilitate
mounting. We recommend that a flexible coupling be employed in order to redu-
ce shock on the gears or geared motor from the machine being driven.
4. Electrical Connection
The electrical connection of the motor may only be performed by personnel with
the appropriate qualification and in compliance with the prescribed safety pre-
cautions and the local regulations governing electrical connections (see para. 1
Safety Instructions). The motor must be connected in accordance with the circuit
diagram in the terminal box. Care must be taken to ensure that the voltage of
the power supply corresponds to that on the performance plate of the motor. Any
additional devices installed, such as brakes, revolution counter generators, and
secondary fans, must comply with the appropriate standards. The direction of
rotation can be changed in three-phase motors by changing two phases, in alter-
nating-current (a.c.) motors by re-clamping the bridges on the terminal board,
and in direct-current (d.c.) motors by changing the polarity of the armature vol-
tage – all this may only be performed when the motor is at standstill!
5. Safety Precautions
The earth lead must without fail be connected to the marked earthing scrow! To
protect it against overloading every motor should be fitted with a trip switch.
Heat-sensitive safety devices react to effective values, and the manufacturer will
design them accordingly when ordered. Where a transformer is used, the volta-
ge must be restricted to the level of the effective nominal voltage.
6. Maintenance
Attention! Before starting any maintenance operations the geared motor must be
permanently disconnected from the mains.
a) Motor:
It is recommended that, depending on the ambient dust arising, the dirt accu-
mulating on the fan cowling of the motor and the motor and gears themsel-
ves should be cleaned off from time to time (heating). In the case of motors
with carbon brushes, these should be checked at regular intervals. The life of
the brushes depends on the mode and conditions of operation. The brushes
must be renewed as and when this becomes necessary. Once the fan cow-
ling, the holding band or the screw-caps have been removed the brushes are
in most cases easily accessible.
b) Gears:
On delivery, the geared motors are ready for use and filled with gear grea-
se or oil. This ensures long-term lubrication for all drive parts and bearings.
No complicated stripping, cleaning or grease change are required. Should,
however, any additional greasing become necessary then synthetic and
mineral lubricants must not be mixed.
7. Closing Remarks
Your attention is drawn to the fact that the contents of the operating and safety
instructions and of the product documentation do not form part of any previous
or existing agreement, undertaking or legal relationship, nor are they designed
to alter such. All the obligations incumbent upon RUHRGETRIEBE are based on
the contract of sale in euch case, which also contains the complete ond solely
applicable regulations relating to the guarantee. The contractual provisions of
the guarantee are neither extended nor restricted by the statements contained in
these operating and safety instructions.
