1.3 Transport and Storage
The frequency inverters must be transported and stored in an appropriate way. During
transport and storage the devices must remain in their original packaging. The units
may only be stored in dry rooms which are protected against dust and moisture and
are exposed to little temperature deviations only. Observe the climatic conditions ac-
cording to EN 50178 and the markin
g on the packaging. The units must not be stored
for more than one year without connecting them to the rated mains voltage.
1.4 Handling and Installation
Warning!
Damaged or destroyed components must not be put into operation be-
cause they may be a health hazard.
The frequency inverters are to be used in accordance with the documentation as well
as the applicable directives and standards. They must be handled carefully and pro-
tected against mechanical stress. Do not bend any components or chan
ge the isolating
distances. Do not touch electronic components or contacts. The devices are equipped
with components which are sensitive to electrostatic energy and can easily be dam-
aged if handled improperly. Any use of dama
ged or destroyed components shall be
considered as a non-compliance with the applicable standards. Do not remove any
warning signs from the device.
1.5 Electrical Connection
Warning!
Before any assembly or connection work, discharge the frequency in-
verter. Verify that the frequency inverter is discharged.
Do not touch the terminals because the capacitors may still be charged.
Comply with the information
given in the operating instructions and on the
frequency inverter label.
When workin
g at the frequency inverters, comply with the applicable standards BGV
A2 (VBG 4), VDE 0100 and other national directives. Comply with the electrical instal-
lation instructions given in the documentation as well as the relevant directives. Re-
sponsibility for compliance with and examination of the limit values of the EMC prod-
uct norm EN 61800-3 for variable-speed electrical drive mechanisms is with the manu-
facturer of the industrial plant or machine.
The documentation contains information on EMC-conformin
g installation. The cables
connected to the frequency inverters may not be subjected to high-voltage insulation
tests unless appropriate circuitry measures are taken before. Otherwise the unit may
be damaged.
