3.5.2
Ambient conditions
In their standard version, MAC R motors are not suitable for working in saline or corrosive atmospheres or for
installation outdoors.
3.5.3
Duty
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: Declassing factors
If the motor does not work in continuous service (S1), but rather in an S2-type temporary 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.
