The controllers must be installed and cooled according to the regulations given
in the documentation.
Ensure proper handling and avoid mechanical stress. Do not bend any
components and do not change any insulation distances during transport or
handling. Do not touch any electronic components and contacts.
Controllers contain electrostatically sensitive components, which can easily be
damaged by inappropriate handling. Do not damage or destroy any electrical
components since this might endanger your health!
When working on live drive controllers, the applicable national regulations for the
prevention of accidents (e.g. VBG 4) must be observed.
The electrical installation must be carried out according to the appropriate
regulations (e.g. cable cross-sections, fuses, PE connection). Additional
information can be obtained from the documentation.
The documentation contains information about installation in compliance with
EMC (shielding, grounding, filters and cables). These notes must also be
observed for CE-marked controllers. The manufacturer of the system or machine
is responsible for the compliance with the required limit values demanded by the
EMC legislation.
Systems including controllers must be equipped with additional monitoring and
protection devices according to the corresponding standards (e.g. technical
equipment, regulations for prevention of accidents, etc.). If necessary, adapt the
controllers to your application. Please observe the corresponding information
given in the Instructions.
After the controller has been disconnected from the supply voltage, live
components and power connection must not be touched immediately since
capacitors could be charged. Please observe the corresponding notes on the
controller.
All covers and doors must be closed during operation.
Note for UL-approved system with integrated controllers: UL warnings are
notes which apply to UL systems. The documentation contains special
information about UL.
Variant V004 of the controller series 9300 and 9300 vector, variant x4x of the
controller series 8200 vector and axis module ECSxAxxx support the function
”Safe standstill”, protection against unintentional restart, according to the
requirements of Appendix I, No. 1.2.7 of the EC Directive ”Machinery” 98/37/EG,
DIN EN 954-1 category 3 and DIN EN 1037. It is absolutely necessary to observe
the information about the function ”Safe standstill” in the corresponding
documentation and instructions.
The controllers do not require any maintenance, if the application conditions
prescribed are observed.
If the ambient air is polluted, the ventilation slots of the controller may be blocked
up. For this reason a regular control of the ventilation slots is necessary. Blocked
ventilation slots must only be cleaned with a vacuum cleaner, never use sharp or
peaked objects!
