Handling
Transport, storage
Observe the notes regarding transport, storage and correct handling. Ensure proper handling
and avoid mechanical stress. Do not bend any components and do not change any insulation
distances during transport or handling. Do not touch any electronic components and contacts.
Inverters contain electrostatically sensitive components which can easily be damaged by inap-
propriate handling. Do not damage or destroy any electrical components since thereby your
health could be endangered!
Installation
The technical data and supply conditions can be obtained from the nameplate and the docu-
mentation. They must be strictly observed.
The inverters have to be installed and cooled according to the regulations given in the corre-
sponding documentation Observe the climatic conditions according to the technical data. The
ambient air must not exceed the degree of pollution 2 according to EN 61800−5−1.
Electrical connection
When working on live inverters, observe the applicable national regulations for the prevention
of accidents.
The electrical installation must be carried out according to the appropriate regulations (e. g.
cable cross-sections, fuses, PE connection). Additional information can be obtained from the
documentation.
This documentation contains information on installation in compliance with EMC (shielding,
earthing, filter, and cables). These notes must also be observed for CE-marked inverters. The
manufacturer of the system is responsible for compliance with the limit values demanded by
EMC legislation. The inverters must be installed in housings (e. g. control cabinets) to meet the
limit values for radio interferences valid at the site of installation. The housings must enable
an EMC-compliant installation. Observe in particular that e. g. the control cabinet doors have
a circumferential metal connection to the housing. Reduce housing openings and cutouts to a
minimum.
Inverters may cause a DC current in the PE conductor. If a residual current device (RCD) is used
for protection against direct or indirect contact for an inverter with three-phase supply, only a
residual current device (RCD) of type B is permissible on the supply side of the inverter. If the
inverter has a single-phase supply, a residual current device (RCD) of type A is also permissi-
ble. Apart from using a residual current device (RCD), other protective measures can be taken
as well, e. g. electrical isolation by double or reinforced insulation or isolation from the supply
system by means of a transformer.
operation
If necessary, systems including inverters must be equipped with additional monitoring and
protection devices. Also comply with the safety regulations and provisions valid at the installa-
tion site.
After the inverter has been disconnected from the supply voltage, all live components and
power terminals must not be touched immediately because capacitors can still be charged.
Please observe the corresponding stickers on the inverter.
All protection covers and doors must be shut during operation.
You may adapt the inverters to your application by parameter setting within the limits availa-
ble. For this, observe the notes in the documentation.
Safety functions
Certain inverter versions support safety functions (e. g. "safe torque off", formerly "safe stand-
still") according to the requirements of the EC Machinery Directive 2006/42/EC. The notes on
the integrated safety provided in this documentation must be observed.
Maintenance and servicing
The inverters do not require any maintenance if the prescribed operating conditions are
observed.
