1.4 Instructions with Regard to Specific Dangers
1.4.1 Protection against Contact with Electrical Parts and Housings
This section concerns components of the electric drive and control
system with voltages of higher than 50 V.
Contact with parts conducting voltages above 50 V can cause personal danger
and electric shock. When operating components of the electric drive and control
system, it is unavoidable that some parts of these components conduct danger-
ous voltage.
High electrical voltage! Danger to life, risk of injury by electric shock or serious
injury!
●Only qualified persons are allowed to operate, maintain and/or repair the
components of the electric drive and control system.
●Follow the general installation and safety regulations when working on power
installations.
●Before switching on, the equipment grounding conductor must have been per-
manently connected to all electric components in accordance with the con-
nection diagram.
●Even for brief measurements or tests, operation is only allowed if the equip-
ment grounding conductor has been permanently connected to the points of
the components provided for this purpose.
●Before accessing electrical parts with voltage potentials higher than 50 V, you
must disconnect electric components from the mains or from the power sup-
ply unit. Secure the electric component from reconnection.
●With electric components, observe the following aspects:
Always wait 30 minutes after switching off power to allow live capacitors to
discharge before accessing an electric component. Measure the electrical
voltage of live parts before beginning to work to make sure that the equip-
ment is safe to touch.
●Install the covers and guards provided for this purpose before switching on.
●Never touch electrical connection points of the components while power is
turned on.
●Do not remove or plug in connectors when the component has been powered.
●Under specific conditions, electric drive systems can be operated at mains
protected by residual-current-operated circuit-breakers sensitive to universal
current (RCDs/RCMs).
●Secure built-in devices from penetrating foreign objects and water, as well as
from direct contact, by providing an external housing, for example a control
cabinet.
Brake Chopper Bosch Rexroth AG
Safety Instructions for Electric Drives and Controls
DOK-RCON04-VFC*BRAKE**-IT01-EN-P 7/65

High housing voltage and high leakage current! Danger to life, risk of injury by
electric shock!
●Before switching on and before commissioning, ground or connect the com-
ponents of the electric drive and control system to the equipment grounding
conductor at the grounding points.
●Connect the equipment grounding conductor of the components of the elec-
tric drive and control system permanently to the main power supply at all
times. The leakage current is greater than 3.5 mA.
1.4.2 Protective Extra-Low Voltage as Protection Against Electric Shock
Protective extra-low voltage is used to allow connecting devices with basic insu-
lation to extra-low voltage circuits.
On components of an electric drive and control system provided by Bosch
Rexroth, all connections and terminals with voltages between 5 and 50 volts are
PELV ("Protective Extra-Low Voltage") systems. It is allowed to connect devices
equipped with basic insulation (such as programming devices, PCs, notebooks,
display units) to these connections.
Danger to life, risk of injury by electric shock! High electrical voltage by incorrect
connection!
If extra-low voltage circuits of devices containing voltages and circuits of more
than 50 volts (e.g., the mains connection) are connected to Bosch Rexroth prod-
ucts, the connected extra-low voltage circuits must comply with the require-
ments for PELV ("Protective Extra-Low Voltage").
1.4.3 Protection against Dangerous Movements
Dangerous movements can be caused by faulty control of connected motors.
Some common examples are:
●Improper or wrong wiring or cable connection
●Operator errors
●Wrong input of parameters before commissioning
●Malfunction of sensors and encoders
●Defective components
●Software or firmware errors
These errors can occur immediately after equipment is switched on or even after
an unspecified time of trouble-free operation.
The monitoring functions in the components of the electric drive and control
system will normally be sufficient to avoid malfunction in the connected drives.
Regarding personal safety, especially the danger of injury and/or property dam-
age, this alone cannot be relied upon to ensure complete safety. Until the inte-
grated monitoring functions become effective, it must be assumed in any case
Bosch Rexroth AG
Safety Instructions for Electric Drives and Controls
Brake Chopper
8/65 DOK-RCON04-VFC*BRAKE**-IT01-EN-P

that faulty drive movements will occur. The extent of faulty drive movements de-
pends upon the type of control and the state of operation.
Dangerous movements! Danger to life, risk of injury, serious injury or property
damage!
A risk assessment must be prepared for the installation or machine, with its spe-
cific conditions, in which the components of the electric drive and control sys-
tem are installed.
As a result of the risk assessment, the user must provide for monitoring func-
tions and higher-level measures on the installation side for personal safety. The
safety regulations applicable to the installation or machine must be taken into
consideration. Unintended machine movements or other malfunctions are possi-
ble if safety devices are disabled, bypassed or not activated.
To avoid accidents, injury and/or property damage:
●Keep free and clear of the machine’s range of motion and moving machine
parts. Prevent personnel from accidentally entering the machine’s range of
motion by using, for example:
– Safety fences
– Safety guards
– Protective coverings
– Light barriers
●Make sure the safety fences and protective coverings are strong enough to re-
sist maximum possible kinetic energy.
●Mount emergency stopping switches in the immediate reach of the operator.
Before commissioning, verify that the emergency stopping equipment works.
Do not operate the machine if the emergency stopping switch is not working.
●Prevent unintended start-up. Isolate the drive power connection by means of
OFF switches / OFF buttons or use a safe starting lockout.
●Make sure that the drives are brought to safe standstill before accessing or
entering the danger zone.
●Disconnect electrical power to the components of the electric drive and con-
trol system using the master switch and secure them from reconnection
("lock out") for:
– Maintenance and repair work
– Cleaning of equipment
– Long periods of discontinued equipment use
●Prevent the operation of high-frequency, remote control and radio equipment
near components of the electric drive and control system and their supply
leads. If the use of these devices cannot be avoided, check the machine or in-
stallation, at initial commissioning of the electric drive and control system, for
possible malfunctions when operating such high-frequency, remote control
Brake Chopper Bosch Rexroth AG
Safety Instructions for Electric Drives and Controls
DOK-RCON04-VFC*BRAKE**-IT01-EN-P 9/65

and radio equipment in its possible positions of normal use. It might possibly
be necessary to perform a special electromagnetic compatibility (EMC) test.
1.4.4 Protection Against Magnetic and Electromagnetic Fields During
Operation and Mounting
Magnetic and electromagnetic fields generated by current-carrying conductors
or permanent magnets of electric motors represent a serious danger to persons
with heart pacemakers, metal implants and hearing aids.
Health hazard for persons with heart pacemakers, metal implants and hearing
aids in proximity to electric components!
●Persons with heart pacemakers and metal implants are not allowed to enter
the following areas:
– Areas in which components of the electric drive and control systems are
mounted, commissioned and operated.
– Areas in which parts of motors with permanent magnets are stored, re-
paired or mounted.
●If it is necessary for somebody with a heart pacemaker to enter such an area,
a doctor must be consulted prior to doing so. The noise immunity of implan-
ted heart pacemakers differs so greatly that no general rules can be given.
●Those with metal implants or metal pieces, as well as with hearing aids, must
consult a doctor before they enter the areas described above.
1.4.5 Protection against contact with hot parts
Hot surfaces of components of the electric drive and control system. Risk of
burns!
●Do not touch hot surfaces of, for example, braking resistors, heat sinks, sup-
ply units and drive controllers, motors, windings and laminated cores!
●According to the operating conditions, temperatures of the surfaces can be
higher than 60 °C (140 °F) during or after operation.
●Before touching motors after having switched them off, let them cool down
for a sufficient period of time. Cooling down can require up to 140 minutes!
The time required for cooling down is approximately five times the thermal
time constant specified in the technical data.
●After switching chokes, supply units and drive controllers off, wait 15 minutes
to allow them to cool down before touching them.
●Wear safety gloves or do not work at hot surfaces.
●For certain applications, and in accordance with the respective safety regula-
tions, the manufacturer of the machine or installation must take measures to
avoid injuries caused by burns in the final application. These measures can
Bosch Rexroth AG

Brake Chopper
10/65 DOK-RCON04-VFC*BRAKE**-IT01-EN-P

be, for example: Warnings at the machine or installation, guards (shieldings or
barriers) or safety instructions in the application documentation.
1.4.6 Protection during handling and mounting
Risk of injury by improper handling! Injury by crushing, shearing, cutting, hitting!
●Observe the relevant statutory regulations of accident prevention.
●Use suitable equipment for mounting and transport.
●Avoid jamming and crushing by appropriate measures.
●Always use suitable tools. Use special tools if specified.
●Use lifting equipment and tools in the correct manner.
●Use suitable protective equipment (hard hat, safety goggles, safety shoes,
safety gloves, for example).
●Do not stand under hanging loads.
●Immediately clean up any spilled liquids from the floor due to the risk of fall-
ing!
