4. Avoid storage in humid environments or in
atmospheres that contain corrosive gases such
as sulferized gas, ammonia gas, or chlorine
gas.
NOTE: is stored or a
where construction work is still being done, keep
prorecred from exposure water and dust
is be placed in service.
INVERTER COMPONENTS AND COOLING
Refer to Figure 2-2 for identification and location of
inverter components. There are two types of cooling
methods depending on the installation method, “cooled
inside control enclosure’ and
outside control
enclosure’ (see Figure 2-3).
lnverters rated 200,250, and 300 HP can be mounted
“Cooled Inside Control Enclosure”. However, a
mounting pedastal will need to be constructed that
can support the weight of the inverter.
This pedastal should mount to the bottom of the
inverter.
NOTE: are shipped the mounted
for ‘cooling inside enclosure’. If outside
enclosure” is required, adapter must be
repositioned (see Figure 2-3).
The mounting adapter, positioned at either the top or
bottom of the enclosure, must be located in accordance
with the installation/cooling method.
With the “cooled outside the enclosure” method, the
cooling fan is mounted externally and approximately
60% of the total heat generated by the inverter is
discharged outside the unit.
NOTE: When cooling fan is
control enclosure, must be periodically cleaned
(especially in environments).
