Ventilation Requirements - Parker AC890 Product Manual

890SD Standalone Drive
Care should be taken in placing the cabinet so that there is sufficient space in front of the cabinet to keep
the exhaust air and inlet air separated. If there is not sufficient space, redirection of the exhaust air is
required. These drives dissipate substantial heat (refer to Appendix E: "Technical Specificatons" –
Electrical Ratings, for Total Power Loss) and therefore sufficient volume for exhaust venting is required to
keep the drive from raising the operating temperature beyond that specified in the Environmental
Specification.
The volumetric airflow rate for each drive is:
G = 583m 3 /hr (343CFM) H = 1505m 3 /hr (884CFM) J = 1753m 3 /hr (1032CFM).

Ventilation Requirements

The drive gives off heat in normal operation and must therefore be mounted to allow the free flow of air
through the ventilation slots and heatsink. Maintain minimum clearances for ventilation, and ensure that
heat generated by other adjacent equipment is not transmitted to the drive. Refer to fold-out drawings
HG465731U001, 2 and 3 at the end of this chapter for information to ensure adequate cooling of the drive.
Be aware that other equipment may have its own clearance requirements. When mounting two or more
890SD units together, these clearances are additive. Ensure that the mounting surface is normally cool.
