Ambient conditions
3.5.2
In their standard version, ID motors are not suitable for working in saline or corrosive atmospheres or for installation outdoors.
Duty
3.5.3
In all the series, unless specified otherwise, the powers assigned for continuous service (S1) apply, with an ambient temperature
of between -20º and +40ºC and at a maximum height of 1000 m above sea level.
If the working conditions differ from those above, a declassing factor must be applied to the torque and power, called K1, with
regard to the values given on the specifications plate, as shown in the following table:

Table 13:
Derating factors
If the motor does not work in continuous duty service (S1), but rather in an S2-type discontinuous service, a multiplication factor
must be applied (K2) to the torque and power specified on the plate (S1 Service) to determine the torque available for the service.
The K2 factor is determined by the duration of the service according to the following graph.
