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 higher-level monitoring devices or measures integrated in the installa-
tion.
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
⇒ Fences and coverings must be strong enough to resist maximum possible
momentum.
⇒ Mount the emergency stop switch in the immediate reach of the operator.
Verify that the emergency stop works before commissioning. Do not operate
the device if the emergency stop switch 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 entering the danger zone.
⇒ Additionally 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 or
● ensuring sufficient equilibration of the vertical axes.
The standard equipment motor brake or an external brake controlled by the
drive controller are not sufficient to guarantee personal safety!
⇒ Disconnect electrical power to the equipment using a master switch and se-
cure 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 positions of normal use before initial commissioning. If necessary,
perform a special electromagnetic compatibility (EMC) test on the installation.
