Ambient/coolant temperature
Operation: T = -15 °C to +40 °C (without derating)
Under conditions other than those specified above (ambient temperature > 40 °C or
installation altitude > 1000 m above sea level), the permissible torque/power reduction must
be determined from the following table. Ambient temperatures and installation altitudes are
rounded off to 5 °C and 500 m respectively.

Note
Higher ambient temperatures
For ambient temperatures > 50 °C, contact your local Siemens office.
The 1PH1 motors are not suitable for use in corrosive atmospheres or atmospheres with a
high salt content, or in outdoor applications.
Minimum clearance between a fan and parts/components mounted by the customer
The minimum clearance between a fan and parts/components mounted by the customer or
the air discharge opening, and the minimum clearance S between the air intake/air discharge
opening and adjacent components must be maintained.

Cleaning the cooling air ducts
On motors with forced ventilation, you must regularly clean the cooling air ducts through
which the ambient air flows. The degree of pollution depends on the location of use. Clean
the air cooling ducts, for example, with dry and oil-free compressed air.
