WARNING
Siemens AG 6SE7087-8NP87-0FB0
SIMOVERT MASTERDRIVES
Safe converter operation requires that the equipment is mounted and
commissioned by qualified personnel taking into account the warning
information provided in these Operating Instructions.
The general and domestic installation and safety regulations for work
on electrical power equipment (e.g. VDE) must be observed as well as
the professional handling of tools and the use of personal protective
equipment.
Death, severe bodily injury or significant material damage could result if
these instructions are not followed.
♦ It is only permissible for radio-interference filters to be used with TN
systems (earthed neutral point).
♦ If mounted in a cabinet, the radio-interference filter must be
mounted directly next to the converter. The cabling is to be kept as
short as possible. The supply cable leading to the radio-interference
filter is to be laid separately from the other cables so that
interference which could cancel the effect of the radio-interference
filter cannot be injected into the interference-suppressed supply
cable.
♦ For high-frequency interference currents, the housings of the
converter and the radio-interference filter must be connected to
each other with low-resistance. This requirement is met by mounting
the converter and the radio-interference filter on a common
mounting plate. The converter and the radio-interference filter are to
be installed so that their bases rest flat on the mounting plate. A
bare metal mounting plate is most suitable, e.g. made of stainless-
steel sheet or galvanized steel sheet, because the whole mounting
surface is used for establishing electrical contact. If the mounting
plate is painted, all the paint must be removed from the screw
connections of the converter and radio-interference filter so that
there is electrical contact with the mounting plate.
It is absolutely necessary that the motor be connected by means of a
shielded cable! The shield is to be flat-connected to the motor and
converter.
