2.4 Designated use
The product is intended for installation in electrical plants or machines.
In case of installation in electrical systems or machines, startup of the product is pro-
hibited until it is determined that the machine meets the requirements stipulated in the
local laws and directives. For Europe, Machinery Directive 2006/42/EC as well as the
EMC Directive 2014/30/EU apply. Observe EN60204-1 (Safety of machinery - elec-
trical equipment of machines). The product meets the requirements stipulated in the
Low Voltage Directive 2014/35/EU.
The standards given in the declaration of conformity apply to the product.
Technical data and information on the connection conditions are provided on the
nameplate and in chapter "Technical data" in the documentation. Always comply with
the data and conditions.
Unintended or improper use of the product may result in severe injury to persons and
damage to property.
Do not use the product as a climbing aid.
2.4.1 Hoist applications
To avoid danger of fatal injury by falling hoists, observe the following points when us-
ing the product in lifting applications:
• Use mechanical protection devices.
• Perform a hoist startup.
2.5 Functional safety technology
The product must not perform any safety functions without a higher-level safety sys-
tem, unless explicitly allowed by the documentation.
2.6 Bus systems
A bus system makes it possible to adapt electronic drive components to the particulars
of the machinery within wide limits. There is a risk that a change of parameters that
cannot be detected externally may result in unexpected (but not uncontrolled) system
behavior and may have a negative impact on operational safety, system availability, or
data security.
Especially in Ethernet-based networked systems and with engineering interfaces,
make sure that unauthorized access is prevented.
Use IT-specific safety standards to increase access protection to the ports. For a port
overview, refer to the respective technical data of the used device.
