R5-rectifiers must be protected against physical damage during tranport,
installation and use. Components and covers must not be bent or moved as this
may affect insulation distances. The equipment must not be switched on if it is
damaged as it may no longer comply with mandatory standards.
This equipment contains electrostatic sensitive devices which may be damaged
by careless handling.
Make sure that during installation there is enough minimum clearance and
enough cooling. Climatic conditions must be observed in accordance with EN
50178.
Electrical Connection
Before any installation and connection work, the system must be switched off
and secured.
The R5-rectifier has a discharge-resistor at the output side. After clearing the
R5-rectifier
Connection of the R5-rectifiers is only permissible on symmetrical networks with
a maximum line voltage (L1, L2, L3) with respect to earth (N/PE) of 300V. An
isolating transformer must be used for supply networks which exceed this value!
The units may be damaged if this is not observed.
The R5-rectifier is only designed for a fixed connection, because when using
filters a leakage current > 3.5mA can occur. Protective conductor cross section
must be at least 10mm2 copper or a 2nd conductor must be electrically parallel
to the protective conductor on separate terminals. Ground point-to-point with
the shortest connection possible to mains earth (avoid earth loops).
When using components without isolated inputs/outputs, it is necessary that
equipotential bonding exists between the components to be connected (e.g.
through the equalizer). Disregard can cause destruction of the components by
the equalizing currents.
A trouble-free and safe operation of the frequency inverter is only guaranteed
when the connection instructions below are strictly followed. Incorrect operation
or damage may result from incorrect installation.
– Note mains voltage and rated motor voltage.
– Make sure the rectifier housing is well grounded. Remove paint finish where
necessary.
– Ground the cabinet or the system earth star point with the shortest connection
to mains earth (avoid earth loops).
The R5-rectifier is not short-circuit proof!
A protection of the mains diods is possible by using of fuses at the input, if I
adapted (see technical data).
