Physical Installation 1 - 14
Installation Orientation and Clearances
Install the Drive vertically so as not to reduce the cooling efficiency. When installing the Drive, always provide the following
installation clearances to allow normal heat dissipation. For 3HP, 208V/240V (CIMR-E7U22P2 and below) or 2HP, 480V
(CIMR-E7U41P5 and below), ensure that the heatsink is against a closed surface to avoid diverting cooling air around the
heatsink.
Fig 1.8 Drive Installation Orientation and Clearance
IMPORTANT
1. 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-E7U2018/4018 and
smaller Drive in a panel.
Always provide enough clearance for lifting eye bolts and the main circuit wiring when installing a
CIMR-E7U2022/4030 and larger Drive in a panel.
