Installation
CAUTION:
Height above sea level: If installing a
SED2 VFD at an altitude higher than
3,280 ft (1000 m), derating is required.
CAUTION:
When locating NEMA Type 3R/3RHE
enclosure, make certain that the
heater/finger guard air inlet (Figures 1
through 3) is not blocked and that any
environmental substance (such as snow
or sand) or other debris will not
potentially block the air inlet.
Mounting
1. Punch appropriate conduit holes for motor and
power wiring (Figures 1 through 3).
CAUTION:
To maintain the NEMA Type
3R/3RHE enclosure rating, use
only fittings rated 3R or rain tight,
or for wet locations.
2. Mount NEMA Type 3R/3RHE Bypass enclosure in
location per job drawings. See Table 1 for
approximate weights and see Figure 4 for
dimensions. Secure enclosure in place.
CAUTION:
Leave 1 foot (305 mm) between
the Bypass and any adjacent
structure that is not used for
mounting purposes. Leave 3 feet
(914 mm) between the Bypass and
any other Bypass or VFD.
