3 Installation of the EM-RES-02 expansion module

3.1 General

The mechanical and electrical installation of the EM-RES-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 operating instructions of the frequency inverter.

Danger! All connection sockets where dangerous volta

e levels may be presen

(e.g. motor connection sockets, mains sockets, fuse connection sockets,

etc.) must be protected against direct contact.

3.2 Mechanical installation

Danger! If the following instructions are not complied with, there is direct dan

with possible consequences of death or severe in

ury by electrical current.

o disre

ard the instructions can lead to destruction of the frequenc

inverter and/or of the expansion module.

• Before assembly or disassembly of the EM-RES-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 be live with dangerous

volta

e after disconnection of the frequency inverter. Work may only be

done on the device after a waitin

period of some minutes until the DC

link capacitors have been discharged.
