§Any overloading of the drives
§Operation in ambient conditions that deviate from those described in the corresponding technical documentation
§Modifying or refitting the drives
§Using the drives for an application other than that defined during project configuration
Commissioning the machine in which the drives are installed is prohibited until it has been determined that the machine
corresponds to regional laws and guidelines. In particular, the (Machinery) Directive 2006/42/EC is to be observed in the
respective scope.
Operation of the drives in potentially explosive atmospheres is prohibited, unless they are expressly designed for this.

performed only by specialized personnel who hold a corresponding qualification in the field of metal technology.
All electrical tasks that arise during the assembly, commissioning, maintenance and removal of the product may be
performed only by electrically skilled persons who hold a corresponding qualification in the field of electrical engineering.
Tasks that arise during transport, storage and disposal may be performed by personnel who have been instructed in the
suitable method for doing so.
Furthermore, personnel who handle the product must carefully read, understand and observe the valid regulations, legal
requirements and applicable basic rules as well as this documentation and the safety instructions it contains.
2.3 Prevention of personal injury
2.3.1 Mechanical hazards
WARNING!
Dangerous movements of machine parts!
Moving machine parts can cause serious injuries or even death!
üBefore starting the motor or drive:
▪ Install all protective devices necessary for operation.
▪ Make sure that no one is standing in the danger area or able to enter it unchecked.
▪ Leave the danger area.

WARNING!
Sinking or falling of gravity-loaded axes or vertical axes after switching off the motor due to gravity!
Falling gravity-loaded axes or vertical axes can cause serious injuries or even death!
▪ Be aware that the holding brake of the motor does not offer sufficient safety for persons that are in the hazard area
of gravity-loaded axes or vertical axes.
▪ Move gravity-loaded axes or vertical axes to their lowest position and lock or brace them mechanically before
allowing people to enter the danger area.
WARNING!
Unsecured feather keys or drive elements can be thrown due to the rotation of the input shaft!
Flying metal parts can cause serious injuries!
▪ Mount the provided drive elements properly or remove them before a test run.
2.3.2 Thermal hazards
CAUTION!
The surface of the drive can reach temperatures over 65°C during operation!
Touching the hot surface of the drive can cause severe skin burns!
▪ Do not touch the drive during operation or immediately afterward.
▪ Allow the drive to cool sufficiently before carrying out work on the drive.
▪ Wear protective gloves when working on the drive.
2.4 Prevention of property damage
ATTENTION!Damage to bearings and shafts due to improper assembly! Never use force when installing machine elements
with fittings, e.g. hitting power transmission elements, shafts or the motor or gear housing with a hammer, but rather
install them in accordance with the following instructions.
ATTENTION!Shaft seal rings can be damaged by solvents! Prevent shaft seal rings from coming into contact with solvents
when cleaning and degreasing unpainted surfaces.

3.4 Mounting positions
STOBER coordinates the lubricant fill volume and structure of the gear unit types listed above to the mounting position of
the gear unit in the machine. The mounting position of a gear unit is determined upon ordering and specified in the order
documents.
The standard mounting positions are illustrated below.
The numbers identify the gear unit sides. The mounting position is defined by the gear unit side facing downwards.
EL1 EL2 EL3
EL4 EL5 EL6
An adhesive label is applied to the gear unit that explains the designated mounting position. The arrow on the adhesive
label indicates the side with which the gear unit must be mounted facing down.
