General notes
Only properly qualifi ed personnel are permitted to perform activities such as transport, in-
stallation, commissioning and maintenance of the ECOSTEP®54.
Th e manufacturer of the machine must generate a hazard analysis for the machine and take
appropriate measures to ensure that unforeseen movements cannot cause injury or damage
to any person or property.
In case of modifi cations or retrofi ts with components of manufacturers other than Jenaer An-
triebstechnik, please contact us to clarify that those components are suitable to be assembled
with our devices.
Emergency-off equipment must be workable in all operation modes, especially during setup

Dangerous voltages
Never open the units during operation. Covers and cabinet doors have to be kept closed du-
ring operation.
Th e protective earth conductor has to be properly applied before applying a voltage.
During operation logic and power conductors are live. Never undo electrical connections
while they are live!
Aft er disconnecting the device wait at least 3 minutes before touching contacts. Capacitors
can still have dangerous voltages present up to 3 minutes aft er switching off the supply volta-
ge. To be sure measure the DC link circuit and wait till it has fallen below 40 V.
2.4
Danger by hot surfaces
Hot surfaces may cause burns to the skin. As the housing of the ECOSTEP®54 serves also as
heat sink during operation the surface temperature may rise to more than 70 °C.
2.5
Danger by unintentional mechanical movements
Unintentional movements of motors, tools or axes may lead to death or serious injuries.
ECOSTEP®54 drives can produce strong mecanical powers and high accelerations. Avoid
