Safety Instructions for Electric Drives and Controls
3.5 Protection Against Contact with Electrical Parts
Touching live parts with voltages of 50 Volts and more with bare hands
or conductive tools or touching ungrounded housings can be danger-
ous and cause electric shock. In order to operate electrical equipment,
certain parts must unavoidably have dangerous voltages applied to
them.
This section refers to equipment and drive components with voltages
above 50 Volts.
DANGER
High electrical voltage! Danger to life, severe bodily harm by elec-
tric shock!
• Only those trained and qualified to work with or on electrical equip-
ment 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 mea-
surements 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 un-
intended.
• The following should be observed with electrical drive and filter com-
ponents:
Wait five (5) minutes after switching off power to allow capacitors to dis-
charge 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 exam-
ple, in a control cabinet.

R911299722 / 02 |Rexroth IndraControl VCP 20 Electric Drives and Controls | Bosch Rexroth AG 3-5
Safety Instructions for Electric Drives and Controls
To be observed with electrical drive and filter components:
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.
DANGER
High electrical voltage on the housing! High leakage current! Dan-
ger 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 per-
manently 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.
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.

Safety Instructions for Electric Drives and Controls
3.7 Protection Against Dangerous Movements
Dangerous movements can be caused by faulty control of the con-
nected 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 inte-
grated 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. Unin-
tended machine motion is possible if monitoring devices are dis-
abled, 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 enter-
ing the machine’s range of motion:
– use safety fences
– use safety guards
– use protective coverings
– install light curtains or light barriers

R911299722 / 02 |Rexroth IndraControl VCP 20 Electric Drives and Controls | Bosch Rexroth AG 3-7
Safety Instructions for Electric Drives and Controls
• 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 op-
erator. 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 ac-
cessing 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.
• 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 di-
rectly 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 instal-
lation for possible malfunctions in all possible positions of normal
use before initial startup. If necessary, perform a special electromag-
netic compatibility (EMC) test on the installation.

• 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 fu-
ture, 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 con-
sult a doctor before they enter the areas described above. Other-
wise, health hazards will occur.
CAUTION
Housing surfaces could be extremely hot! Danger of injury! Danger
of burns!

Safety Instructions for Electric Drives and Controls
3.12 Protection Against Pressurized Systems
Certain motors and drive controllers, corresponding to the information
in the respective Project Planning Manual, must be provided with pres-
surized media, such as compressed air, hydraulic oil, cooling fluid and
cooling lubricant supplied by external systems. Incorrect handling of
the supply and connections of pressurized systems can lead to injuries
or accidents. In these cases, improper handling of external supply sys-
tems, supply lines or connections can cause injuries or material dam-
age.
CAUTION
Danger of injury by incorrect handling of pressurized systems!
• Do not attempt to disassemble, to open or to cut a pressurized sys-
tem (danger of explosion).
• Observe the operation instructions of the respective manufacturer.
• Before disassembling pressurized systems, release pressure and
drain off the fluid or gas.
• Use suitable protective clothing (for example safety glasses, safety
shoes and safety gloves)
• Remove any fluid that has leaked out onto the floor immediately.
Environmental protection and disposal! The media used in the operation
of the pressurized system equipment may not be environmentally com-
patible. Media that are damaging the environment must be disposed
separately from normal waste. Observe the legal requirements in the
country of installation.
