REMARQUE
Le chapitre suivant est toujours en anglais indépendamment de la langue de la
présente documentation et ce, en raison des prescriptions UL.
Observe the following notes for UL-compliant installation:
•
Use 75 °C copper wire only.
•
DRC uses cage clamp terminals
Suitable for use on a circuit capable of delivering not more than 200,000 rms symmetri-
cal amperes when protected by 40 A, 600 V non-semiconductor fuses or 500 V mini-
mum 40 A maximum inverse time circuit breakers.
•
DRC, the max. voltage is limited to 500 V.
Integral solid state short circuit protection does not provide branch circuit protection.
Branch circuit protection must be provided in accordance with the National Electrical
Code and any additional local codes.
The table below list the permitted maximum branch circuit protection:
Series
DRC
DRC is provided with load and speed-sensitive overload protection and thermal memory
retention upon shutdown or power loss.
The trip current is adjusted to 150% of the rated motor current.
DRC is suitable for an ambient temperature of 40 °C, max. 60 °C with derated output
current. To determine the output current rating at temperatures above 40 °C, the output
current should be derated by 3.0% per K between 40 °C and 60 °C.
For wiring diagrams, refer to chapter "Electrical installation".
