3.2 Intended use
B&R motors and gear motors are components designed for installation in electrical systems or machines. They were
designed, developed and manufactured for general industrial use. They are intended to be operated in covered
rooms and under normal climatic conditions, which is usually the case in modern production halls. When used
in residential areas, commercial areas or small businesses, additional filtering measures are required or must be
provided by the user. Only operate the motor with B&R drive systems.
Use in accordance with the intended purpose is prohibited until:
•It has been determined that the machine complies with the provisions of EC Directive 2006/42/EC (Ma-
chinery Directive) and EMC Directive 2014/30/EU.
•All values specified on the nameplate and in the user's manual (e.g. connection and ambient conditions)
have been observed.
3.3 Reasonably foreseeable misuse
Use of this product in areas with fatal risks or dangers is prohibited!
Danger!
Severe personal injury and damage to property due to failure!
When used without ensuring exceptionally high safety measures, death, injury, severe physical im-
pairments or other serious losses are possible.
Do not use the product in the following areas, as well as other areas associated with fatal risks or
dangers:
•Explosive areas
•Monitoring nuclear reactions in nuclear power plants
•Flight control systems and air traffic control
•Controlling mass transport systems
•Medical life support systems
•Controlling weapons systems
In special cases – use in non-commercial installations – with additional requirements (e.g. protection
of children's fingers), these requirements must be satisfied during setup on the system side.
3.4 General sources of danger
Tampering of protection or safety devices
Protective and/or safety devices protect you and other persons from dangerous voltage, rotating or moving ele-
ments and hot surfaces.
Danger!
Personal injury and damage to property due to tampering of protective equipment!
If protective or safety devices are removed or put out of operation, there is no longer any personal
protection and serious personal injury and damage to property can occur.
•Do not remove any safety devices.
•Do not put any safety devices out of operation.
•Always use all safety devices during short-term test and trial operations!
Dangerous voltage
To operate the motors, dangerous voltage must be applied to certain parts.

General information • Safety
Chapter 1
General information
8JSA user's manual V1.00 7
Danger!
Risk of injury due to electric shock!
If live parts are touched, there is immediate danger of fatal electric shock.
If connections are connected or disconnected in the incorrect order or when the power is switched on,
electric arcs can occur and persons and contacts can be damaged.
Even if the motor is not rotating or is running as a generator driven externally, the control and power
connections can still carry voltage!
•Never touch connections when the power is switched on.
•Never disconnect or connect electrical connections to the motor and servo drive when the
power is switched on!
•Do not stay in the danger zone during operation and secure it against access by unauthorized
persons.
•Always operate the motor with all safety equipment. Do this even during short testing and trial
operations!
•Keep all covers and control cabinet doors closed during operation and as long as the machine
is not disconnected from the power system.
•Before working on motors, gearboxes or servo drives or in the danger zone of your machine,
disconnect them completely from the power system and secure them against being switched
on again by other persons or automatic systems.
•Note the discharge time of any existing DC bus.
•Only connect measuring instruments when the power is switched off!
Danger due to electromagnetic fields
Electromagnetic fields are generated by the operation of electrical power engineering equipment such as trans-
formers, drives and motors.
Danger!
Danger to health due to electromagnetic fields!
The functionality of a heart pacemaker can be impaired by electromagnetic fields to such an extent
that the wearer experiences harm to his or her health, possibly with a fatal outcome.
•Observe relevant national health and safety regulations.
•Persons with pacemakers are not allowed to be in endangered areas.
•Warn staff by providing information, warnings and safety identification.
•Secure the danger zone by means of barriers.
•Reduce electromagnetic fields at their source (using shielding, for example).
Dangerous motion
By rotating and positioning motions of the motors, machine elements are moved or driven and loads conveyed.
After switching on the machine, movements of the motor shaft must always be expected! For this reason, high-
er-level protective measures must be put in place to ensure that personnel and machines are protected. This type
of protection can be achieved, for example, by using stable mechanical protective equipment such as protective
covers, protective fences, protective gates or photoelectric sensors.
In the immediate vicinity of the machine, provide sufficient and easily accessible emergency switching-off devices
to stop the machine as quickly as possible in the event of an accident.

Danger!
Danger of injury due to rotating or moving elements and loads!
By rotating or moving elements, body parts can be drawn in or severed or subjected to impacts.
•Do not stay in the danger zone during operation and secure it against access by unauthorized
persons.
•Before working on the machine, secure it against unwanted movements. Any holding brake
present is not suitable for this!
•Keep all covers and control cabinet doors closed during operation and as long as the machine
is not disconnected from the power system.
•Always operate the motor with all safety equipment. Do this even during short testing and trial
operations!
•Motors can be started automatically via remote control! If appropriate, a corresponding warning
symbol must be applied, and protective measures must be implemented to prevent entry into
the high-risk area.
Warning!
Danger of injury due to incorrect control or a defect.
Improper control of motors or a defect can result in injuries and unintended and hazardous movements
of motors.
Such incorrect behavior can be triggered by:
•Incorrect installation or faults when handling components
•Improper or incomplete wiring
•Defective devices (servo drive, motor, position encoder, cables, brake)
•Incorrect control (e.g. caused by software error)
Risk due to hot surfaces
Due to the power dissipation from the motor and friction in the gearbox, these components as well as their envi-
ronment can reach a temperature of more than 100°C.
The resulting heat is released to the environment via the housing and the flange.
Warning!
Risk of burns due to hot surfaces!
Touching hot surfaces (e.g. motor and gearbox housings, as well as connected components), can lead
to very severe burns due to the very high temperature of these parts.
•Do not stay in the danger zone during operation and secure it against access by unauthorized
persons.
•Never touch the motor or gearbox housing as well as adjacent surfaces during nominal load
operation.
•Be aware of hot surfaces also during downtime.
•Allow motor and gearbox to cool sufficiently before working on it. This is because there is still
a risk of burning for a prolonged period of time even after shutting down.
•Always operate the motor or gearbox with all safety devices. Do this even during short testing
and trial operations!
