emergency stop works before startup. Don’t operate the device if the emergency 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 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 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
,
repair work
,
cleaning of equipment
and
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 startup. If necessary, perform a special electromagnetic compatibility (EMC) test
on the installation.
Protection against Magnetic and Electromagnetic Fields during Operation and
Mounting
Magnetic and electromagnetic fields generated by current-carrying conductors and permanent
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 electrical equipment!
»
Persons with heart pacemakers and metal implants are not permitted to enter 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, repaired 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.
Protection against Contact with Hot Parts
Hot surfaces at motor housings, on drive controllers or chokes! Danger of injury!
Danger of burns!
»
Do not touch surfaces of device housings and chokes in the proximity of heat sources! Danger
of burns!
