REXRTOHRexroth EcoDrive 03 Drive Controllers DKC**.3-040, -100, -200

• improper or wrong wiring of cable connections

• incorrect operation of the equipment components

• wrong input of parameters before commissioning

• malfunction of sensors, encoders and monitoring devices

• If the device is resold, rented and/or passed on to others in any other

form, these safety instructions must be delivered with the device in the

official language of the user's country.

• Proper and correct transport, storage, assembly and installation as

well as care in operation and maintenance are prerequisites for

optimal and safe operation of this device. Observe the data contained

in the corresponding product documentations.

Improper use of these devices, failure to follow the safety instructions in this document or tampering with the product, including disabling of safety devices, may result in material damage, bodily harm, electric shock or even death! ⇒ Observe the following safety instructions!

Contact with Electrical Parts

DANGER

High electrical voltage! Danger to life, electric shock and severe bodily injury!

• Follow general construction and safety regulations when working on power installations.

• Before switching on the device, the equipment grounding conductor must have been

non-detachably connected to all electrical equipment and motors in accordance with the

connection diagram.

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. The

leakage current is greater than 3.5 mA.

Over the total length, use copper wire of a cross section of a minimum of 10 mm2

 for

this equipment grounding connection!

• Before working with electrical parts with voltage potentials higher than 50 V, the device

must be disconnected from the mains voltage or power supply unit. Provide a safeguard

to prevent reconnection.

• Wait 30 minutes after switching off power to allow capacitors to discharge before

beginning to work. Measure the electric 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 or r.c.d. cannot be used for electric drives!

Indirect contact must be prevented by other means, for example, by an overcurrent

protective device according to the relevant standards.

Handling and Assembly

CAUTION

Risk of injury by improper handling! Bodily injury by bruising, shearing, cutting, hitting!

• Observe the general construction and safety regulations on handling and assembly.

• Use suitable devices for assembly and transport.

• Avoid jamming and bruising by appropriate measures.

• Always use suitable tools. Use special tools if specified.

• Use lifting equipment and tools in the correct manner.

• If necessary, use suitable protective equipment (for example safety goggles, safety shoes,

safety gloves).

• Do not stand under hanging loads.

• Immediately clean up any spilled liquids because of the danger of skidding.

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 commissioning

• malfunction of sensors, encoders and monitoring devices

• defective components

Courtesy 

• 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 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 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!

• For the above reasons, ensure personal safety by means of qualified and tested higherlevel monitoring devices or measures integrated in the installation.

They have to be provided for by the user according to the specific conditions within the

installation and a hazard and fault analysis. The safety regulations applicable for the

installation have to be taken into consideration. Unintended machine motion or other

malfunction 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 motion:

– use safety fences

– use safety guards

– use protective coverings

– install light curtains or light barriers
