Derating data, PM240 Power Modules

Pulse frequency

¹⁾ The pulse frequency can only be switched over from 4 kHz (default) to 2 kHz for the low overload (LO) duty cycle.

Ambient temperature

Low overload (LO) for PM240 Power Modules, frame size FSF

High overload (HO) for PM240 Power Modules, frame size FSF

Note:

The operating temperature ranges of the Control Units should be taken into account. The temperature ranges are specified in the section Technical specifications under Control Units.

Installation altitude

Permissible line supplies depending on the installation altitude

• Installation altitude up to 2000 m above sea level

- Connection to every supply system permitted for the inverter

• Installation altitudes between 2000 m and 4000 m above sea level

- Connection to a TN system with grounded neutral point

- TN systems with grounded line conductor are not permitted

- The TN line system with grounded neutral point can also be supplied using an isolation transformer

- The phase-to-phase voltage does not have to be reduced

Note:

The connected motors, power elements and components must

be considered separately.
