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 insulaon
distances during transport or handling. Do not touch any electronic components and contacts.
Inverters contain electrostacally sensive 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!
Installaon
The technical data and supply condions can be obtained from the nameplate and the docu-
mentaon. They must be strictly observed.
The inverters have to be installed and cooled according to the regulaons given in the corre-
sponding documentaon Observe the climac condions according to the technical data. The
ambient air must not exceed the degree of polluon 2 according to EN 61800−5−1.
Electrical connecon
When working on live inverters, observe the applicable naonal regulaons for the prevenon
of accidents.
The electrical installaon must be carried out according to the appropriate regulaons (e. g.
cable cross-secons, fuses, PE connecon). Addional informaon can be obtained from the
documentaon.
This documentaon contains informaon on installaon in compliance with EMC (shielding,
earthing, lter, 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 legislaon. The inverters must be installed in housings (e. g. control cabinets) to meet the
limit values for radio interferences valid at the site of installaon. The housings must enable
an EMC-compliant installaon. Observe in parcular that e. g. the control cabinet doors have
a circumferenal metal connecon 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 protecon 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 protecve measures can be taken
as well, e. g. electrical isolaon by double or reinforced insulaon or isolaon from the supply
system by means of a transformer.
operaon
If necessary, systems including inverters must be equipped with addional monitoring and
protecon devices. Also comply with the safety regulaons and provisions valid at the installa-
on site.
Aer the inverter has been disconnected from the supply voltage, all live components and
power terminals must not be touched immediately because capacitors can sll be charged.
Please observe the corresponding sckers on the inverter.
All protecon covers and doors must be shut during operaon.
You may adapt the inverters to your applicaon by parameter seng within the limits availa-
ble. For this, observe the notes in the documentaon.
Safety funcons
Certain inverter versions support safety funcons (e. g. ”safe torque o”, formerly ”safe stand-
sll”) according to the requirements of the EC Machinery Direcve 2006/42/EC. The notes on
the integrated safety provided in this documentaon must be observed.
Maintenance and servicing
The inverters do not require any maintenance if the prescribed operang condions are
observed.
