3.5 Protection Against Contact with Electrical Parts
Note: This section refers to equipment and drive components with
voltages above 50 Volts.
Touching live parts with voltages of 50 Volts and more with bare hands or
conductive tools or touching ungrounded housings can be dangerous and
cause electric shock. In order to operate electrical equipment, certain
parts must unavoidably have dangerous voltages applied to them.
DANGER
High electrical voltage! Danger to life, severe
bodily harm by electric shock!
⇒ Only those trained and qualified to work with or on
electrical equipment are permitted to operate, maintain
or repair this equipment.
⇒ Follow general construction and safety regulations when
working on high voltage installations.
⇒ Before switching on power the ground wire must be
permanently connected to all electrical units according
to the connection diagram.
⇒ Do not operate electrical equipment at any time, even
for brief measurements or tests, if the ground wire is not
permanently connected to the points of the components
provided for this purpose.
⇒ Before working with electrical parts with voltage higher
than 50 V, the equipment must be disconnected from
the mains voltage or power supply. Make sure the
equipment cannot be switched on again unintended.
⇒ The following should be observed with electrical drive
and filter components:
⇒ Wait five (5) minutes after switching off power to allow
capacitors to discharge before beginning to work.
Measure the voltage on the capacitors before beginning
to work to make sure that the equipment is safe to
touch.
⇒ Never touch the electrical connection points of a
component while power is turned on.
⇒ Install the covers and guards provided with the
equipment properly before switching the equipment on.
Prevent contact with live parts at any time.
⇒ A residual-current-operated protective device (RCD)
must not be used on electric drives! Indirect contact
must be prevented by other means, for example, by an
overcurrent protective device.
⇒ Electrical components with exposed live parts and
uncovered high voltage terminals must be installed in a
protective housing, for example, in a control cabinet.

VAK 11.2 / VAK 41.2 Safety Instructions for Electric Drives and Controls 3-5
DOK-SUPPL*-VAK*11/41**-PR02-EN-P
To be observed with electrical drive and filter components:
DANGER
High electrical voltage on the housing!
High leakage current! Danger to life, danger of
injury by electric shock!
⇒ Connect the electrical equipment, the housings of all
electrical units and motors permanently with the safety
conductor at the ground points before power is
switched on. Look at the connection diagram. This is
even necessary for brief tests.
⇒ Connect the safety conductor of the electrical
equipment always permanently and firmly to the
supply mains. Leakage current exceeds 3.5 mA in
normal operation.
⇒ Use a copper conductor with at least 10 mm²cross
section over its entire course for this safety conductor
connection!
⇒ Prior to startups, even for brief tests, always connect
the protective conductor or connect with ground wire.
Otherwise, high voltages can occur on the housing
that lead to electric shock.
3.6 Protection Against Electric Shock by Protective Low
Voltage (PELV)
All connections and terminals with voltages between 0 and 50 Volts on
Rexroth products are protective low voltages designed in accordance with
international standards on electrical safety.
WARNING
High electrical voltage due to wrong
connections! Danger to life, bodily harm by
electric shock!
⇒ Only connect equipment, electrical components and
cables of the protective low voltage type (PELV =
Protective Extra Low Voltage) to all terminals and
clamps with voltages of 0 to 50 Volts.
⇒ Only electrical circuits may be connected which are
safely isolated against high voltage circuits. Safe
isolation is achieved, for example, with an isolating
transformer, an opto-electronic coupler or when
battery-operated.

3-6 Safety Instructions for Electric Drives and Controls VAK 11.2 / VAK 41.2
DOK-SUPPL*-VAK*11/41**-PR02-EN-P
3.7 Protection Against Dangerous Movements
Dangerous movements can be caused by faulty control of the connected
motors. Some common examples are:
•improper or wrong wiring of cable connections
•incorrect operation of the equipment components
•wrong input of parameters before operation
•malfunction of sensors, encoders and monitoring devices
•defective components
•software or firmware errors
Dangerous movements can occur immediately after equipment is
switched on or even after an unspecified time of trouble-free operation.
The monitoring in the drive components will normally be sufficient to avoid
faulty operation in the connected drives. Regarding personal safety,
especially the danger of bodily injury and material damage, this alone
cannot be relied upon to ensure complete safety. Until the integrated
monitoring functions become effective, it must be assumed in any case
that faulty drive movements will occur. The extent of faulty drive
movements depends upon the type of control and the state of operation.
DANGER
Dangerous movements! Danger to life, risk of
injury, severe bodily harm or material damage!
⇒ Ensure personal safety by means of qualified and
tested higher-level monitoring devices or measures
integrated in the installation. Unintended machine
motion is possible if monitoring devices are disabled,
bypassed or not activated.
⇒ Pay attention to unintended machine motion or other
malfunction in any mode of operation.
⇒ Keep free and clear of the machine’s range of motion
and moving parts. Possible measures to prevent
people from accidentally entering the machine’s range
of motion:
- use safety fences
- use safety guards
- use protective coverings
- install light curtains or light barriers
⇒ Fences and coverings must be strong enough to
resist maximum possible momentum, especially if
there is a possibility of loose parts flying off.
⇒ Mount the emergency stop switch in the immediate
reach of the operator. Verify that the emergency stop
works before startup. Don’t operate the machine if the
emergency stop is not working.
⇒ Isolate the drive power connection by means of an
emergency stop circuit or use a starting lockout to
prevent unintentional start.
⇒ Make sure that the drives are brought to a safe
standstill before accessing or entering the danger
zone. Safe standstill can be achieved by switching off
the power supply contactor or by safe mechanical
locking of moving parts.

VAK 11.2 / VAK 41.2 Safety Instructions for Electric Drives and Controls 3-7
DOK-SUPPL*-VAK*11/41**-PR02-EN-P
⇒ Secure vertical axes against falling or dropping after
switching off the motor power by, for example:
- mechanically securing the vertical axes
- adding an external braking/ arrester/ clamping
mechanism
- ensuring sufficient equilibration of the vertical axes
The standard equipment motor brake or an external
brake controlled directly by the drive controller are
not sufficient to guarantee personal safety!
⇒ Disconnect electrical power to the equipment using a
master switch and secure the switch against
reconnection 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 electronics circuits
and supply leads. If the use of such equipment cannot
be avoided, verify the system and the installation for
possible malfunctions in all possible positions of
normal use before initial startup. If necessary, perform
a special electromagnetic compatibility (EMC) test on
the installation.
3.8 Protection Against Magnetic and Electromagnetic Fields
During Operation and Mounting
Magnetic and electromagnetic fields generated near current-carrying
conductors and permanent magnets in motors represent a serious health
hazard to persons with heart pacemakers, metal implants and hearing
aids.
WARNING
Health hazard for persons with heart
pacemakers, metal implants and hearing aids in
proximity to electrical equipment!
⇒ Persons with heart pacemakers, hearing aids and
metal implants are not permitted to enter the following
areas:
- Areas in which electrical equipment and parts are
mounted, being operated or started up.
- Areas in which parts of motors with permanent
magnets are being stored, operated, repaired or
mounted.
⇒ If it is necessary for a person with a heart pacemaker
to enter such an area, then a doctor must be
consulted prior to doing so. Heart pacemakers that
are already implanted or will be implanted in the
future, have a considerable variation in their electrical
noise immunity. Therefore there are no rules with
general validity.
⇒ Persons with hearing aids, metal implants or metal
pieces must consult a doctor before they enter the
areas described above. Otherwise, health hazards will
occur.

4.3 Compatibility Test
All Rexroth controls and drives are developed and tested according to the
latest state-of-the-art.
As it is impossible to follow the continuing development of all materials
(e.g. lubricants in machine tools) which may interact with our controls and
drives, it cannot be completely ruled out that any reactions with the
materials used by Bosch Rexroth might occur.
For this reason, before using the respective material a compatibility test
has to be carried out for new lubricants, cleaning agents etc. and our
housings/our housing materials.
