WARNING
● Persons with heart pacemakers and metal implants are not permitted to enter the
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, re‐
paired 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.

a doctor before they enter the areas described above. Otherwise health hazards
may occur.

Protection Against Contact with Hot Parts

CAUTION
● Do not touch surfaces of device housings and chokes in the proximity of heat sour‐
ces! Danger of burns!
● Do not touch housing surfaces of motors! Danger of burns!
● According to operating conditions, temperatures can be higher than 60 °C, 140 °F
during or after operation.
● Before accessing motors after having switched them off, let them cool down for a
sufficiently long time. Cooling down can require up to 140 minutes! Roughly estima‐
ted, the time required for cooling down is 5 times the thermal time constant specified
in the Technical Data.
● After switching drive controllers or chokes off, wait for 15 minutes to allow them to
cool down before touching them.
● Wear safety gloves or do not work at hot surfaces.
● For certain applications, the manufacturer of the end product, machine or installa‐
tion, according to the respective safety regulations, has to take measures to avoid
injuries caused by burns in the end application. These measures can be, for exam‐
ple: warnings, guards (shielding or barrier), technical documentation.
