03/12 EM-ABS-01 for ACU 17
5 Installation
5.1 General
The mechanical and electrical installation of the EM-ABS-01 extension module must be
carried out by qualified personnel accordin
to the
eneral and re
ional safety and
installation directives. For a safe operation of the frequency inverter it is necessary
that the documentation and the device specifications be complied with during installa-
tion and commissionin
. In the case of special applications, you may also have to
comply with further guidelines and instructions.
he frequency inverters are desi
ned accordin
to the requirements and limit values
of product norm EN 61800-3 with an interference immunity factor (EMI) for operation
in industrial applications. The electroma
netic 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!
ll connection terminals where dan
erous volta
e levels may be present
(e.g. motor connection terminals, mains terminals, fuse connection ter-
minals, etc.), must be protected against direct contact.
5.2 Mechanical Installation
Danger! If the followin
instructions are not complied with, there is direct dan
er
with the possible consequences of death or severe in
ury by electrical
current. Further, failure to comply can lead to destruction of the frequency
inverter and/or of the extension module.
• Before assembly or disassembly of the EM-ABS-01 extension module, the frequen-
cy inverter must be de-energized. Take appropriate measures to make sure it is
not energized unintentionally.
• Make sure that the frequency inverter is discharged.
Danger! When the frequency inverter is disconnected from power supply, the
mains, DC-link volta
e and motor terminals may still be live for some
time. Wait for at least three minutes until the DC link capacitors have
discharged before starting to work at the unit.
