3 Installation of the EM-SYS expansion module
3.1 General
The mechanical and electrical installation of the EM-SYS 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 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 present
(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 following instructions are not complied with, there is direct danger
with the possible consequences of death or severe injury by electrical
current. Further, failure to comply can lead to destruction of the fre-
quency inverter and/or of the expansion module.
• Before assembly or disassembly of the EM-SYS expansion module, the frequency
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 sockets can have dangerous voltages
even 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.
