2.6 Instructions with Regard to Specific Dangers
Protection Against Contact with Electrical Parts
This section only concerns devices and drive components with voltages of
more than 50 V. Contact with parts conducting voltages above 50 V can
cause personal danger and electric shock. When operating electrical
equipment, it is unavoidable that some parts of the devices conduct dan‐
gerous voltage.
High electrical voltage! Danger to life, electric shock
and severe bodily injury!
DANGER
● Only those trained and qualified to work with or on electrical equipment are permit‐
ted to operate, maintain and repair this equipment.
● Follow general construction and safety regulations when working on electrical power
installations.
● Before switching on the device, the equipment grounding conductor must have been
non-detachably connected to all electrical equipment in accordance with the connec‐
tion diagram.
● Do not operate electrical equipment at any time, even for brief measurements or
tests, if the equipment grounding conductor is not permanently connected to the
mounting points of the components provided for this purpose.
● Before working with electrical parts with voltage potentials higher than 50 V, the de‐
vice must be disconnected from the mains voltage or power supply unit.
● With electrical drive and filter components, observe the following:
– Wait for 10 minutes after switching off power to allow capacitors to discharge be‐
fore beginning to work.
DOK-RCON03-EFC-3600***-IT01-EN-P
Rexroth Frequency Converter EFC 3600
Bosch Rexroth AG
Safety Instructions for Electric Drives and Controls
13/235

– 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 device on. Before switching the equipment on, cover and safeguard live parts
safely to prevent contact with those parts.
● A residual-current-operated circuit-breaker cannot be used for electric drives! Indi‐
rect contact must be prevented by other means, for example, by an over current pro‐
tective device according to the relevant standards.
● Secure built-in devices from direct touching of electrical parts by providing an exter‐
nal housing. For example: a control cabinet.
Always observe the above requirements, in accordance with relevant inter‐
national standards.
With electrical drive and filter components, observe the following:
High housing voltage and large leakage current!
Risk of death or bodily injury by electric shock!
DANGER
● Before switching on, the housings of all electrical equipment and motors must be
connected or grounded with the equipment grounding conductor to the grounding
points. This is also applicable before short tests.
● The equipment grounding conductor of the electrical equipment and the units must
be non-detachably and permanently connected to the power supply unit at all times.
● Over the total length, use copper wire of a cross section of a minimum of 10 mm2 for
this equipment grounding connection!
● Before start-up, also in trial runs, always attach the equipment grounding conductor
or connect with the ground wire. Otherwise, high voltages may occur at the housing
causing electric shock.

2.7 Protection Against Electric Shock by Protective Low Volt‐
age (PELV)
High electric voltage by incorrect connection! Risk
of death or bodily injury by electric shock!
WARNING
● To all connections and terminals with voltages between 0 and 50 V, only devices,
electrical components, and conductors may be connected which are equipped with a
PELV (Protective Extra-Low Voltage) system.
● Connect only voltages and circuits which are safely isolated from dangerous voltag‐
es. Safe isolation is achieved for example by isolating transformers, safe optocou‐
plers or battery operation without mains connection.
2.8 Protection Against Dangerous Movements
Dangerous movements can be caused by faulty control of 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 opera‐
tion in the connected drives. Regarding personal safety, especially the danger of bodily
harm 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 de‐
pends upon the type of control and the state of operation.
Dangerous movements! Danger to life, risk of injury,
severe bodily harm or material damage!
DANGER
● For the above reasons, ensure personal safety by means of qualified and tested
higher-level monitoring devices or measures integrated in the installation. They have
to be provided for by the user according to the specific conditions within the installa‐
tion and a hazard and fault analysis. The safety regulations applicable for the instal‐

Rexroth Frequency Converter EFC 3600
Bosch Rexroth AG
Safety Instructions for Electric Drives and Controls
15/235

lation have to be taken into consideration. Unintended machine motion or other mal‐
function is possible if safety devices are disabled, bypassed or not activated.
To avoid accidents, bodily harm and/or material damage:
● 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 mo‐
tion:
– Use safety fences
– Use of safety guard (cover)
– Use of protective coverings
– Install light curtains or light barrier
● Fences and coverings must be strong enough to resist maximum possible momen‐
tum.
● Mount the emergency stop switch in the immediate reach of the operator. Verify that
the emergency stop works before start-up. Don’t operate the device if the emergen‐
cy stop is not working.
● Isolate the drive power connection by means of an emergency stop circuit or use a
safety related starting lockout to prevent unintentional start.
● Make sure that the drives are brought to a safe standstill before accessing or enter‐
ing the danger zone.
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 devices cannot be avoided,
verify the system and the installation for possible malfunctions in all possible posi‐
tions of normal use before initial start-up. If necessary, perform a special electro‐
magnetic compatibility (EMC) test on the installation.
2.9 Protection Against Magnetic and Electromagnetic Fields
During Operation and Mounting
Magnetic and electromagnetic fields generated by current-carrying conductors and per‐
manent magnets in motors represent a serious personal danger to those with heart
pacemakers, metal implants and hearing aids.

Health hazard for persons with heart pacemakers,
metal implants and hearing aids in proximity to elec‐
trical equipment!
WARNING
● Persons with heart pacemakers and metal implants are not permitted to enter the
following areas:
– Areas in which electrical equipment and parts are mounted, being operated or
commissioned
– Areas in which parts of motors with permanent magnets are being stored, re‐
paired or mounted
● If it is necessary for somebody with a pacemaker to enter such an area, a doctor
must be consulted prior to doing so. The interference immunity of present or future
implanted heart pacemakers differs greatly, so 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. Otherwise health hazards
may occur.
2.10 Protection Against Contact with Hot Parts
Hot surfaces at motor housings, on drive controllers
or chokes! Danger of injury! Danger of burns!
CAUTION
● Do not touch surfaces of device housings and chokes in the proximity of heat sour‐
ces! Danger of burns!
● Do not touch housing surfaces of motors! Danger of burns!
● According to operating conditions, temperatures can be higher than 60 °C, 140 °F
during or after operation.
● Before accessing motors after having switched them off, let them cool down for a
sufficiently long time. Cooling down can require up to 140 minutes! Roughly estima‐
ted, the time required for cooling down is 5 times the thermal time constant specified
in the Technical Data.
● After switching drive controllers or chokes off, wait for 15 minutes to allow them to
cool down before touching them.
● Wear safety gloves or do not work at hot surfaces.
● For certain applications, the manufacturer of the end product, machine or installa‐
tion, according to the respective safety regulations, has to take measures to avoid
injuries caused by burns in the end application. These measures can be, for exam‐
ple: warnings, guards (shielding or barrier), technical documentation.
