Figure 2.2 shows the required installation spacing to maintain sufficient space for airflow and wiring for IP20/NEMA 1, UL
Type 1 and IP66/NEMA 4X, UL Type 4X enclosures. Install the heatsink against a closed surface to avoid diverting cooling
air around the heatsink.
A – 30 mm minimum
B – Airflow direction
Note: IP20/NEMA 1, UL Type 1 and IP66/NEMA 4X, UL Type 4X enclosure models require the same amount of space above and below the
drive for installation.
Multiple Drive Installation

When installing multiple drives into the same enclosure panel, mount the drives according to
drives with a minimum side-by-side clearance of 2 mm according to
L8-35 must be set.

A – Line up the tops of the drives.
B – 30 mm minimum
Note: When installing drives of different heights in the same enclosure panel, the tops of the drives should line up. Leave space between the top
and bottom of stacked drives for cooling fan replacement if required. Using this method, it is possible to replace the cooling fans later.
