3.1
The mechanical and electrical installation of the EM-ENC-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 in 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 interference immunity factor (EMI) for operation
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.

Installation of the EM-ENC-03 expansion module
General
All connection sockets where dangerous voltage levels may be present
(e.g. motor connection sockets, mains sockets, fuse connection sockets,
etc.), must be protected against direct contact.
Mechanical installation
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-ENC-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.
The mains, direct voltage and motor sockets can be live with dangerous
voltages after disconnection of the frequency inverter. Work may only be
done on the device after a waiting period of some minutes until the DC
link capacitors have been discharged.
