6.2.10 Wall/Panel Mount Installation

Only the D1h and D2h are recommended to be wall
mounted outside an enclosure due to their IP21 (NEMA 1)
and IP54 (NEMA 12) rating. While the D3h and D4h units
can be wall mounted, it is recommended they be panel
mounted inside an enclosure. The E2 unit is designed only
to be panel mounted within an enclosure.
To install a wall- or panel-mounted unit, perform the
following steps:
1. Make sure there is at least 225 mm (8.9 in) of
space between the top of the unit and the
ceiling, and at least 225 mm (8.9) space between
the unit and the floor to provide for adequate
cooling.
2. Make sure there is enough space for cable entry
at the bottom of the unit.
3. Mark the mounting holes according to the instal-
lation drawings and drill holes where indicated.
4. Mount the bolts at the bottom of the unit and lift
the frequency converter up on the bolts.
5. Tilt the frequency converter against the wall and
mount the upper bolts.
6. Tighten all 4 bolts to secure the unit against the
wall.

6.2.11 Pedestal Installation of D-frames

The D7h and D8h frequency converters are shipped with a
pedestal and a wall spacer. Before securing the enclosure
to the wall, install the pedestal behind the mounting
flange as shown in Illustration 6.99.
