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.
