Protection during handling and mounting

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
minutes! The time required for cooling down is approximately five times
the thermal time constant specified in the technical data.
● After switching chokes, supply units and drive controllers off, wait 15 mi‐
nutes to allow them to cool down before touching them.
● Wear safety gloves or do not work at hot surfaces.
● For certain applications, and in accordance with the respective safety
regulations, the manufacturer of the machine or installation must take
measures to avoid injuries caused by burns in the final application.
These measures can be, for example: Warnings at the machine or in‐
stallation, guards (shieldings or barriers) or safety instructions in the ap‐
plication documentation.
Risk of injury by improper handling! Injury by crushing, shearing, cutting, hit‐
ting!
● Observe the relevant statutory regulations of accident prevention.
● Use suitable equipment for mounting and transport.
● Avoid jamming and crushing by appropriate measures.
● Always use suitable tools. Use special tools if specified.
● Use lifting equipment and tools in the correct manner.
● Use suitable protective equipment (hard hat, safety goggles, safety
shoes, safety gloves, for example).
