Installation and Operating Instructions

1.3.1 General Instructions

• Install KEB COMBIVERT stationary and ground it.
• Take into consideration the minimum distance to surrounding elements when
positioning the inverter. (see control cabinet installation)
• Rack units are designed for vertical installation and can be mounted side by
side. Maintain a distance of at least 50mm to preceding elements. Make sure
cooling is sufficient.
• No mist or water may get into the KEB COMBIVERT.
• Prevent dust from getting into the KEB COMBIVERT. When installing a dust-
proof housing make sure it has enough heat dissipation.
• Do not operate KEB COMBIVERT in an explosion-protected room!
In explosion-protected rooms the KEB COMBIVERT must be installed in an
explosion-protected housing, in observance of the local regulations.
• Protect the KEB COMBIVERT against conductive and aggressive gases and
liquids.
• Consumers, which produce electrical or magnetic fields or have an influence
on the voltage supply, must be placed as far away as possible and measures
must be taken to suppress the influences.
• Regarding applications, that require cyclic switching off and on of the static
frequency inverter, a minimum time-out of at least 5 minutes must be kept
after power-off. If shorter cycle times are needed, please contact KEB.
• The life span of the KEB COMBIVERT, an inverter with voltage link, depends
on the current load of the electrolytic capacitors in the intermediate circuit. By
using line reactors the life span of the capacitors can be substantial increased,
in particular when connecting to a „hard" network or in case of continuous
load (S1 operation) on the drive.
For drives in continuous operation (S1) with an average load of >60% KEB
recommends the use of line reactors with Uk=4%.
The term „hard" network can be defined as follows (as assistance):
The rated power of the inverter (Sn) is very small in comparison to the nodal
point rating (Smains) of the mains.
k = Smains / Sn >> 200 e.g.
Smains = 2 MVA
––> k = 303
––> line reactor necessary
Sn = 6,6 kVA 12.F5
