Safety Instructions for Electric Drives and Controls
3.8
Protection Against Magnetic and Electromagnetic Fields During
Operation and Mounting
Magnetic and electromagnetic fields generated near current-carrying
conductors and permanent magnets in motors represent a serious
health hazard to persons with heart pacemakers, metal implants and
hearing aids.
•
Fences and coverings must be strong enough to resist maximum
possible momentum, especially if there is a possibility of loose parts
flying off.
•
Mount the emergency stop switch in the immediate reach of the op-
erator. Verify that the emergency stop works before startup. Don’t
operate the machine if the emergency stop is not working.
•
Isolate the drive power connection by means of an emergency stop
circuit or use a starting lockout to prevent unintentional start.
•
Make sure that the drives are brought to a safe standstill before ac-
cessing or entering the danger zone. Safe standstill can be achieved
by switching off the power supply contactor or by safe mechanical
locking of moving parts.
•
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
–
ensuring sufficient equilibration of the vertical axes
The standard equipment motor brake or an external brake controlled di-
rectly 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 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 equipment cannot be avoided, verify the system and the instal-
lation for possible malfunctions in all possible positions of normal
use before initial startup. If necessary, perform a special electromag-
netic compatibility (EMC) test on the installation.
WARNING
Health hazard for persons with heart pacemakers, metal implants and
hearing aids in proximity to electrical equipment!
