7 INSTALLATION INSTRUCTIONS
OPDE DC-DC has to be installed under the ambient conditions specified in the section "Limits of use" and in
compliance with the following instructions:
1) Position the OPDE DC-DC converter observing the minimum positioning measures.
2) Connect the OPDE DC-DC converter to the wall using screws, according to the dimensions shown.
3) Prevent metallic residues resulting from drilling or works performed on connection electrical cables from falling
into the converter.
4) In no case, the converter has to be mounted close to easily flammable materials.
IT IS COMPULSORY TO HAVE AUTHORIZED OPERATORS PERFORM THE INSTALLATION OF THE
OPDE DC-DC CONVERTER
IT IS COMPULSORY TO INSTALL THE OPDE DC-DC CONVERTER BEING SURE THAT THE
ELECTRICAL PANEL TO WHICH IT IS GOING TO BE CONNECTED DOES NOT SHOW ANY POWER
SUPPLY.
ANY OPERATION WITHIN THE OPDE DC-DC CONVERTER MUST BE DONE WITHOUT VOLTAGE
PRESENCE AND, IN ANY CASE, WAIT FOR AT LEAST 8 MIN. BEFORE ACCESSING THE SAME (FIG.
2).
IT IS COMPULSORY TO INSTALL THE OPDE DC-DC CONVERTER ONLY IN VERTICAL POSITION
BECAUSE ONLY IN THIS WAY HEAT CONVECTION IS NOT HINDERED, WHICH WOULD CAUSE
DAMAGES. IF IT IS NECESSARY TO INSTALL THE CONVERTER IN NON VERTICAL POSITION
CONTACT THE TECHNICIAN OF BDF DIGITAL TO EVALUATE THE SITUATION CASE BY CASE.
IT IS COMPULSORY TO ASSURE A GOOD ACCESS TO ALL THE CONTROL ELEMENTS.
OPDE DC-DC MUST NECESSARILY BE INSTALLED CLOSE TO THE SUPPORT WALL IN ORDER TO
PROPERLY CHANNEL THE AIR FLOW IN THE HEAT SINK.
IT IS COMPULSORY TO INSTALL SEVERAL OPDE DC-DC DRIVES SIDE BY SIDE TO ASSURE A
GOOD VENTILATION AND PREVENT THE COOLING AIR FLOW OF A CONVERTER FROM
AFFECTING THE OTHER.
THE CONVERTER INSTALLATION SHALL NOT HINDER ACCESS TO DISCONNECTING AND
CUTTING-OFF TOOLS.
IF THE CONVERTER IS USED IN A DIFFERENT WAY THAN THOSE SPECIFIED BY THE
MANUFACTURER, THE PROTECTIONS PROVIDED BY THE CONVERTER ARE NOT GUARANTEED.
CLOSED ENVIRONMENT: DISSIPATED POWER 7.1
TAB. 11 indicates the power dissipated by the converter operating at rated current, including adjustment, ventilation
and power IGBT losses. During an installation in a closed environment, e.g. in a cabinet, it is necessary to make sure
that the inner temperature does not exceed the ambient temperature permissible for the converter. The environment
has to be ventilated with a sufficient air quantity as to remove the heat generated by the same and by the other
components.
