Application Description

and Controls

2.2.2

Protection Against Electric Shock by Protective Extra-Low

Voltage

Protective extra-low voltage is used to allow connecting devices with basic insula-

tion to extra-low voltage circuits.

All connections and terminals with voltages between 5 and 50 volts at Rexroth

products are PELV systems

. It is therefore allowed to connect devices equipped

with basic insulation (such as programming devices, PCs, notebooks, display

units) to these connections and terminals.

2.2.3

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

These errors 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 dan-

ger of bodily harm and/or material damage, this alone cannot be relied upon to en-

sure 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 oper-

ation.

"Protective Extra-Low Voltage"

High electric voltage by incorrect connection! Risk of death or bodi-

ly injury by electric shock

If extra-low voltage circuits of devices containing voltages and circuits of more

than 50 volts (e.g. the mains connection) are connected to Rexroth products, the

connected extra-low voltage circuits must comply with the requirements for

PELV
