Physical Installation 1 - 12Installation Orientation and ClearancesInstall the Drive vertically so as not to reduce the cooling efficiency. When installing the Drive, always provide the followinginstallation clearances to allow normal heat dissipation and air flow. Ensure that the heatsink is against a closed surface toavoid diverting cooling air around the heatsink.Fig 1.8 Drive Installation Orientation and ClearanceIMPORTANT1. The same clearance is required horizontally and vertically for both Open Chassis (IP00)and NEMA Type 1 Drives.2. Always remove the top and bottom protection covers before installing a CIMR-F7U2018/4018 and smaller Drive in a panel.3. Always provide enough clearance for lifting eye bolts and the main circuit wiring wheninstalling a CIMR-F7U2022/4030 and larger Drive in a panel.4.75in * 2 (120mm) minimum4.75in (120mm) minimumAirAirVertical ClearanceHorizontal Clearance1.2in(30.5mm) minimum1.2in(30.5mm) minimum1.97in (50mm) minimum1.97in * 1 (50mm) minimum*1 For Drive models F7U2110, F7U4160, and F7U4220, this clearance dimension is 4.75in (120mm) minimum.For Drive model F7U4300, this clearance dimension is 11.8in (300mm) minimum.All other models require 1.97in (50mm) minimum.*2 For Drive model F7U4300, this clearance dimension is 11.8in (300mm) minimum.
