Electrical and temperature parameters.

The power supply voltage and frequency are indicated on the name
plates and (or) on the electric wiring diagram.
The minimum ambient temperature is -4°F (-20°C) and the maximum
+140°F (60°C) unless another information is mentioned on the name
plates.
6.3 Special operation conditions including incorrect
practices.
Duty cycle: 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 table 2).
