3 Installation of the EM-IO-02 expansion module
3.1 General
The mechanical and electrical installation of the EM-IO-02 expansion module is to be
carried out by qualified personnel accordin
to the
eneral and re
ional safety and
installation directives. Safe operation of the frequency inverter requires that the
documentation and the device specification be complied with durin
installation and
start of operation. For specific areas of application further provisions and
uidelines
must be complied with where applicable.
he frequency inverters are desi
ned accordin
to the requirements and limit values
of product standard EN 61800-3 with an interference immunity factor (EMI) for opera-
tion in industrial applications. The electromagnetic interference is to be avoided by
expert installation and observation of the specific product information.
For further information, refer to the chapter "Electrical Installation" of the frequency
inverter operating instructions.
Warning! All connection terminals where dangerous voltage levels may be presen
(e.g. motor connection terminals, mains terminals, fuse connection ter-
minals, etc.), must be protected against direct contact.
3.2 Mechanical installation
Danger! If the followin
instructions are not complied with, there is direct dan
er
with possible consequences of death or severe in
ury by electrical current.
o disre
ard the instructions can lead to destruction of the frequenc
converter and/or of the expansion module.
• Before assembly or disassembly of the EM-IO-02 expansion module, the fre-
quency inverter must be de-ener
ized. Take appropriate measures to make sure i
is not energized unintentionally.
• Make sure that the frequency inverter is de-energized.
Danger! The mains, direct voltage and motor sockets can have dangerous volta
es
even after disconnection of the frequency converter. Work may only be
done on the device after a waitin
period of some minutes until the DC
link capacitors have been discharged.
