Attention
Voltage with respect to ground
Connection of the COMBIVERT is only permissible on symmetrical networks with a maxi-
mum line voltage (L1, L2, L3) with respect to earth (N/PE) of 305V. The units may be dam-
aged if this is not observed.
Attention
Leakage currents > 3.5 mA
According to EN 61800-5-1 the requirement must be fulfilled that safety is maintained in
case of destruction or separation of the protective earth conductor. At COMBIVERT, leakage
currents >3.5 mA occur especially when using EMC filters.
For stationary connection
• use a cross-section of the protective earth conductor of min. 10 mm² (copper) or 16 mm²
(aluminum)
or
• an automatic disconnection of the mains in case of interruption of the protective earth
conductor shall be provided
or
• use an additional terminal for a second protective earth conductor with the cross-section
as the original protective earth conductor
Attention
Insulation measurement
When doing an insulation measurement in accordance with VDE 0100 / Part 620, the power
semiconductor of the unit and existing radio interference filters must be disconnected be
-
cause of the danger of destruction. This is permissible in compliance with the standard,
since all inverters are given a high voltage test in the end control at KEB in accordance with
EN 61800-5-1.
Attention
Different earth potentials
Use an additional line for equipotential bonding for the connection of terminals to compo-
nents that have no potential isolated inputs / outputs.
Disregard can lead to malfunctions or defects.
