Location Distance Description
Sides
305 mm (12″) or
914 mm (36″)
The minimum side clearances are 305 mm (12″) on one side
of the inverter and 914 mm (36″) on the other side to allow
access to the external mounting flanges. The installer may
select which side has clearance. The 914 mm (36″) will
provide future access to the magnetics section for retorquing
bolts and thermal scans of connections. However, the 914 mm
(36″) on the side is not a NEC setback requirement. 305 mm
(12″) on each side is an acceptable installation practice.
Top 457 mm (18″)
The top clearance is required above the air intake hood to
maintain the filters and fans.
Clearances are shown in the figure below.

Figure 3‑1. Inverter clearances
Only one side, right or left, is recommended to have the full 914 mm (36″) clearance
while the remaining side must have 305 mm (12″). The above example demonstrates
305 mm (12″) on the left with 914 mm (36″) on the right side. This allows access to
the magnetics section for retorquing bolts and thermal scan of connections. This is
not a code setback requirement and 305 mm (12″) on each side is an acceptable
installation practice.
