● 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.
● 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 counterbalancing of the vertical axes.
● The standard equipment motor holding brake or an external holding brake controlled
by the drive controller is not sufficient to guarantee personal safety!
● Disconnect electrical power to the components of the electric drive and control sys‐
tem 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 installation, at initial com‐
missioning of the electric drive and control system, for possible malfunctions when
operating such high-frequency, remote control and radio equipment in its possible
positions of normal use. It might possibly be necessary to perform a special electro‐
magnetic compatibility (EMC) test.
1.1.4 Protection Against Magnetic and Electromagnetic Fields During
Operation and Mounting
Magnetic and electromagnetic fields generated by current-carrying conductors or per‐
manent magnets of electric motors represent a serious danger to persons with heart
pacemakers, metal implants and hearing aids.
Health hazard for persons with heart pacemakers, metal implants and hearing aids in
proximity to electric components!
● Persons with heart pacemakers and metal implants are not allowed to enter the fol‐
lowing areas:
– Areas in which components of the electric drive and control systems are moun‐
ted, commissioned and operated.
