3.2 ELECTRICAL INSTALLATION
DANGER!
 The following information is merely a guide for proper installation. Comply
with applicable local regulations for electrical installations.
 Make sure the power supply is disconnected before starting the installation.
 The CFW500 must not be used as an emergency stop device. Provide other
devices for that purpose.
DANGER!
 Les informations suivantes constituent uniquement un guide pour une
installation correcte. Respectez les réglementations locales en vigueur pour
les installations électriques.
 Vérifiez que l'alimentation secteur CA est débranchée avant de commencer
l'installation.
 Le CFW500 ne devra pas être utilisé comme un dispositif d'arrêt d'urgence.
Utilisez des dispositifs additionnels appropriés dans ce but.
ATTENTION!
 Integral solid state short circuit protection does not provide branch circuit
protection. Branch circuit protection must be provided in accordance with
applicable local codes.
3.2.1 Identification of the Power Terminals and Grounding Points
The power terminals can be of different sizes and configurations, depending on the model of
the inverter, according to Figure B.4 on page 174. The location of the power, grounding and
control connections are shown in Figure A.3 on page 155.
Description of the power terminals:
 L/L1, N/L2 and L3 (R, S, T): AC power supply. Some models of voltage 200-240 V (see
option of models in Table B.1 on page 157 and Table B.2 on page 159 can operate in 2 or 3
phases (single-phase/three-phase inverters) without derating of the rated current. In this case,
the AC power supply can be connected to two of the three input terminals without distinction.
For the single-phase models only, the power voltage must be connected to L/L1 and N/L2.
 U, V, W: connection for the motor.
 -UD: negative pole of the voltage of the DC Link.
 BR: connection of the brake resistor.
 +UD: positive pole of the voltage of the DC Link.
 DCR: connection to the external DC Link inductor (optional). Only available for models 28 A,
33 A, 47 A and 56 A / 200-240 V and 24 A, 31 A, 39 A and 49 A / 380-480 V.
The maximum torque of the power terminals and grounding points must be checked in Figure
B.4 on page 174.
