Protection against electromagnetic and magnetic fields during opera‐
tion and mounting
3.3.5
Protection against contact with hot parts

●
Additionally secure vertical axes against falling or dropping after switch‐
ing 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 per‐
sonal safety!
●
Disconnect electrical power to the components of the electric drive and
control system using the master switch and secure them from reconnec‐
tion ("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 equip‐
ment 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 commissioning of the electric drive and
control system, for possible malfunctions when operating such high-fre‐
quency, 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.
Electromagnetic and magnetic fields!
Health hazard for persons with active implantable medical devices (AIMD)
such as pacemakers or passive metallic implants.
●
Hazards for the above-mentioned groups of persons by electromagnetic
and magnetic fields in the immediate vicinity of drive controllers and the
associated current-carrying conductors.
●
Entering these areas can pose an increased risk to the above-men‐
tioned groups of persons. They should seek advice from their physician.
●
If overcome by possible effects on above-mentioned persons during op‐
eration of drive controllers and accessories, remove the exposed per‐
sons from the vicinity of conductors and devices.
Hot surfaces of components of the electric drive and control system. Risk of
burns!
●
Do not touch hot surfaces of, for example, braking resistors, heat sinks,
supply units and drive controllers, motors, windings and laminated
cores!
●
According to the operating conditions, temperatures of the surfaces can
be higher than 60 °C (140 °F) during or after operation.
●
Before touching motors after having switched them off, let them cool
down for a sufficient period of time. Cooling down can require up to 140
