REMARQUE
Le chapitre suivant est toujours en anglais, indépendamment de la langue de la pré-
sente documentation et ce en raison des prescriptions UL.
Ambient Temperature
The units in IP20 are suitable for an ambient temperature of 50 °C, max. 60 °C.
The units in IP55/IP66 are suitable for an ambient temperature of 40 °C, max 50 °C.
Thermal motor protection
Thermal motor overload protection shall be provided by one of the following means:
•
•
•
Parameter
The following parameter must be set to enable the internal thermal motor protection
according to NEC:
•
Functional principle
The motor current is accumulated in an internal memory over the course of time. The
inverter goes to fault state as soon as the thermal limit is exceeded (I.t-trP).
Once the output current of the inverter is less than the set rated motor current, the in-
ternal memory is decremented depending on the output current.

NEC compliant installation of a motor temperature sensor, see also section "Motor
temperature protection (TF/TH)" in the chapter "Electrical Installation" of the opera-
ting instructions.
Using internal thermal motor overload protection according to NEC (National Elec-
trical Code, US). Thermal motor overload protection can be activated via parame-
ter P4-17.
Implementing external measures to ensure thermal motor overload protection
according to NEC (National Electrical Code).
P4-17 Thermal motor protection according to NEC
– 0: disabled
– 1: enabled
When P4-17 is disabled, thermal memory retention is reset upon shutdown or po-
wer loss.
When P4-17 is enabled, thermal memory retention is maintained upon shutdown
or power loss.
