EM-RES-03 910/07
4 Installation of the EM-RES-03 expansion module
4.1 General
The mechanical and electrical installation of the EM-RES-03 expansion module is to be
carried out by qualified personnel according to the general and regional safety and
installation directives. Safe operation of the frequency inverter requires that the
documentation and the device specification be complied with durin
g installation and
start of operation. For specific areas of application further provisions and guidelines
must be complied with where applicable.
The frequency inverters are designed according 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 electroma
gnetic interference is to be avoided by
expert installation and observation of the specific product information.
For further information, refer to the operating instructions of the frequency inverter.
Warning! All connection sockets where dan
erous volta
e levels may be presen
(e.g. motor connection sockets, mains sockets, fuse connection sockets,
etc.) must be protected against direct contact.
4.2 Mechanical installation
Danger! If the followin
instructions are not complied with, there is direct dan
er
with possible consequences of death or severe injury by electrical current.
To disregard the instructions can lead to destruction of the frequency
inverter and/or of the expansion module.
• Before assembly or disassembly of the EM-RES-03 expansion module, the fre-
quency inverter must be de-energized. Take appropriate measures to make sure it
is not energized unintentionally.
• Make sure that the frequency inverter is de-energized.
Danger! The mains, direct voltage and motor terminals can be live with dangerous
voltage after disconnection of the frequency inverter. Work may only be
done on the device after a waitin
g period of some minutes until the DC
link capacitors have been discharged.
