Information on electrical installation

Preparation

When implementing machines and systems for the use in the UL/CSA scope, you
have to observe the relevant special notes.
These notes are marked with "UL marking".
WARNING!
▶ UL marking
▶ Suitable for motor group installation.
▶ 0.55 kW ... 30 kW devices on a circuit capable of delivering not more than 5k rms symmetri-
cal amperes, 480 V maximum when protected by fuses or circuit breakers. Ratings see table
below.
▶ Devices from 45 kW on a circuit capable of delivering not more than 10k rms symmetrical
amperes, 480 V maximum when protected by fuses. Ratings see table below.
▶ Marquage UL
▶ Convient pour une installation de groupes de moteurs.
▶ Appareils de 0,55 kW à 30 kW sur un circuit non susceptible de délivrer plus de 5k A en
valeur efficace, à 480 V maximum et avec une protection par fusibles ou par disjoncteurs. Se
reporter au tableau ci-dessous pour connaître les caractéristiques assignées.
▶ Appareils à partir de 45 kW sur un circuit non susceptible de délivrer plus de 10k A en
valeur efficace, à 480 V maximum et avec protection par fusibles. Se reporter au tableau ci-
dessous pour connaître les caractéristiques assignées.
You have to install the devices into housings (e. g. control cabinets) to comply
with valid regulations.
Stickers with warning notes must be displayed prominently and close to the
device.

4EMC-compliant installation
4Standards and operating conditions
The scope of supply of the inverter comprises mounting instructions. They
describe technical data and information on mechanical and electrical installa-
tion.
A good shield connection at the transitions of the different areas reduce possible interferen-
ces caused by problems with the EMC.
