Siemens SINAMICS PERFECT HARMONY GH180 - Air-To-Air Heat Exchanged (W41) Drive Preparation

on the front side (special duct interface jobs require alternative pre-engineered blower module
and are not provided as standard options bu Siemens).
Air is exhausted out of the front of the blower section in standard con󹪝guration products. Air will
be exhausted out of the back of the blower section only when rear ducting option is selected.
Provision is provided to cycle redundant blowers periodically by means of the control interface
from the NXG control.
Note
See customer outline prints for blower con󹪝guration when M58 option code is selected. Type 4/
IP66 Outdoor Enclosure is de󹪝ned in the Appendix entitled "Technical Data".
CAUTION
Never energize the drive without operational blowers providing air 󹪞ow.
When power is applied to the drive that is operating in an IDLE condition state, blowers must
be operational to remove heat generated by component losses. Failure to provide air 󹪞ow for
heat dissipation could result in damage to the drive or its components,
Applying Medium Voltage without air 󹪞ow will result in a trip from the Coordinated Input
Protection Scheme.
To remove the unit's latent heat, Siemens recommends running the blower for ten minutes
after removing Medium Voltage.

NOTICE
To avoid serious personal injury, accidental death, or major property damage, read and follow
all safety instructions in manual provided with heat exchanger. Maintain all safety labels in
good condition. If necessary, replace labels using provided part numbers.
Use of an air-to-air heat exchanger is an alternative solution to use of fans in air-cooled drives.
Whenever heat exchanger cooling method is selected by customer, the fans shipping split are
not required. Additional parts such as plenums and exhaust hood may be required. Some of
these parts may be shipping splits depending upon each speci󹪝c design. Refer to project speci󹪝c
outline and assembly drawings provided by Siemens for more detail.
Follow procedures in this manual and other respective manuals delivered with the drive for
additional information about handling, installation, commissioning and maintenance of drive.
Heat Exchanger
The heat exchanger may be shipped with or without the drive. It usually ships in multiple
shipping splits.
