Cooling Section

Cooling System Components
The cooling system consists of several parts including blower(s). Each blower has a suitably
rated three-phase combination starter (circuit breaker & contactor combination). There is an
optional line reactor that is connected upstream to the combination starter in the circuit that
feeds an EMI filter.
Cooling System Function
The cooling system functions as follows:
● The line reactor connects to a combination starter (circuit breaker & contactor combination).
The contactor is controlled through the SOP of the NXG controller.
● The output of the combination starter (circuit breaker & contactor combination) connects
to quick disconnect plugs which connect individual blowers to the power source.
● The default SOP logic is configured to operate the blower immediately when control power
is energized.
● If the blower (or blowers) fails or loses power, the SOP logic controller issues a drive trip.
This fault condition must be manually reset.

Blowers and Speed Settings

Blowers
All SINAMICS PERFECT HARMONY GH180 air-cooled drives are force air-cooled.
An extremely important part of the installation process is making provisions for exhausting the
heat that is generated by the operation of the drive. Although the drive is highly efficient, there
