2.8 -
After a failure due to connection mistakes or others, in the drives could arise a temporary hot spot.
For this reason avoid absolutely to install in explosive or flammable environments.
Avoid also to
install near easily flammable materials and components;
we recommend to verify that all the
components located in the enclosure are realized using self-extinguishing materials.
2.9 -
All products considered in this manual are sub-assemblies without a direct function, foreseen to be
integrated in a more complex machine. Only a professional assembler, expert in the field of motor
drives and in their related problems, can install and put in service this component. It is exclusive
responsibility of the designer of the complete machine or installation in which this component is used
to take care of the safety and reliability of his project. It is forbidden to use this material in application
covered from one or more EEC directives (for instance 2014/30/UE, 2006/42/CE, etc.) before the
conformity to those directives has been declared. Regarding 2014/30/UE directive, see chapter 10.
2.10 - Use for safety related functions is forbidden (EN 60204-1). Moreover, when the application
arrangement is in such way that a drive fault or failure could generate a dangerous condition,
external independent safety protection system must be provided in the machine.
2.11 - In some case of drive failure, dangerous high voltage could appear at logic low voltage input and
output terminals, even if this event is extremely rare. For this reason, from the point of view of
evaluation of the machine safety during a single fault condition, the external control system,
connected to these inputs, has to be considered potentially subjected to high voltage, unless an
external separation is provided.
2.12 - Both CURRENT OFF input signal (see chapter 4) and internal electronic functional protections (see
chapter 6) switch off the drive output power by means of semiconductor devices. They cannot be
used to interrupt power in emergency stop function or in any function involving personnel safety.
2.13 - Remote overload protection is required (see figure 7a and 7b). [
Integral solid state short circuit
protection does not provide branch circuit protection. Branch circuit protection must be provided in
accordance with the Manufacturer Instructions, National Electrical Code and any additional local
code
