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, serious injury or property
damage!
A risk assessment must be prepared for the installation or machine, with its spe-
cific conditions, in which the components of the electric drive and control sys-
tem are installed.
As a result of the risk assessment, the user must provide for monitoring func-
tions and higher-level measures on the installation side for personal safety. The
safety regulations applicable to the installation or machine must be taken into
consideration. Unintended machine movements or other malfunctions are possi-
ble if safety devices are disabled, bypassed or not activated.
To avoid accidents, injury and/or property damage:
Keep free and clear of the machine's range of motion and moving machine
●
parts. Prevent personnel from accidentally entering the machine's range of
motion by using, for example:
– Safety fences
– Safety guards
– Protective coverings
– Light barriers
Make sure the safety fences and protective coverings are strong enough to re-
●
sist maximum possible kinetic energy.
Mount emergency stopping switches in the immediate reach of the operator.
●
Before commissioning, verify that the emergency stopping equipment works.
Do not operate the machine if the emergency stopping switch is not working.
Prevent unintended start-up. Isolate the drive power connection by means of
●
OFF switches/OFF buttons or use a safe starting lockout.
Make sure that the drives are brought to safe standstill before accessing or
●
entering the danger zone.
Disconnect electrical power to the components of the electric drive and con-
●
trol system using the master switch and secure them from reconnection
("lock out") 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 components of the electric drive and control system and their supply
leads. If the use of these devices cannot be avoided, check the machine or in-
stallation, at initial commissioning of the electric drive and control system, for
possible malfunctions when operating such high-frequency, remote control
