Installation
The power supply modules must be installed and cooled according to the instructions
given in the corresponding 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.
Power supply modules 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!
Electrical connection
When working on live power supply modules, the valid 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.
Notes about installation according to EMC regulations (shielding, earthing, filters and
cable routing) are included in the documentation. These notes also apply to CE−marked
power supply modules. The compliance with limit values required by the EMC legislation
is the responsibility of the manufacturer of the machine or system.
Operation
If necessary, systems including power supply modules must be equipped with additional
monitoring and protection devices according to the valid safety regulations (e.g. law on
technical equipment, regulations for the prevention of accidents). The power supply
modules can be adapted to your application. Please observe the corresponding
information given in the documentation.
After a power supply module has been disconnected from the voltage supply, all live
components and power connections must not be touched immediately because capacitors
can still be charged. Please observe the corresponding stickers on the power supply
module.
All protection covers and doors must be shut during operation.
Note for UL approved systems with integrated power supply modules: UL warnings are
notes that only apply to UL systems. The documentation contains special UL notes.
Maintenance and servicing
The power supply modules do not require any maintenance if the prescribed conditions of
operation are observed.
If the ambient air is polluted, the cooling surfaces of the power supply module may become
dirty or the air vents of the power supply module may be obstructed. Therefore, clean the
cooling surfaces and air vents periodically under these operating conditions. Do not use
sharp or pointed tools for this purpose!
