1.6 ELECTRICAL AND TEMPERATURE PARAMETERS
The power supply voltage and frequency are indicated on the identification tag and (or) on the electric
wiring diagram.
The minimum ambiant temperature is -20°C and the maximum +40°C unless an other information
is mentioned on the identification tag.
1.7 SPECIAL OPERATION CONDITIONS INCLUDING UNCORRECT
PRACTICES
Duty cycle: the motors are designed for an intermittent operation ; it means that they should
be stopped for a sufficient period of time after each operation in order to enable it to cool down (see §1.4
operation). If the operating time is too high, the motor temperature will raise and will eventually activate
the thermal protection. This event must remain exceptional and everything must be carried out to avoid
switching the thermal protection during normal operation phases.
Covers opening: remove the covers only if there is no explosive atmosphere. It is important
not to degrade the explosion proof protections (surfaces, cable glands, gaskets, ...).
