Protection During Handling and Mounting
Rexroth IndraMotion MTX 09VRS | Application Description
and Controls
Magnetic and electromagnetic fields generated by current-carrying conductors
and permanent magnets in motors represent a serious personal danger to
those with heart pacemakers, metal implants and hearing aids.
Health hazard for persons with heart pacemakers, metal implants and
hearing aids in proximity to electrical equipment!
●
Persons with heart pacemakers and metal implants are not permitted to
enter 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, repaired 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 noise immunity of pres‐
ent or future implanted heart pacemakers differs greatly so that no general
rules can be given.
●
Those with metal implants or metal pieces, as well as with hearing aids,
must consult a doctor before they enter the areas described above. Oth‐
erwise health hazards may occur.
Hot surfaces at motor housings, on drive controllers or chokes! Danger
of injury! Danger of burns!
●
Do not touch surfaces of device housings and chokes in the proximity of
heat sources! Danger of burns!
●
Do not touch housing surfaces of motors! Danger of burns!
●
According to the 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 mi‐
nutes! Roughly estimated, the time required for cooling down is five times
the thermal time constant specified in the Technical Data.
●
After switching drive controllers or chokes off, wait 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
installation, 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 example: warnings, guards (shielding or barrier),
technical documentation.
In unfavorable conditions, handling and mounting certain parts and compo‐
nents in an improper way can cause injuries.
