Inverter placement (Installation of Filterpack)
1.5.4
Installation precautions
(1) Above inverter
Heat is blown up from inside the inverter by the small fan built in the unit. Any equipment placed above the inverter should be
heat resistant.
(2) Arrangement of multiple inverters (Filterpacks)
(3) Arrangement of ventilation fan and inverter (Filterpack)
When multiple inverters (Filterpacks) are placed in the
same enclosure, generally arrange them horizontally as
shown in the right figure (a). When it is inevitable to
arrange them vertically to minimize space, take such
measures as to provide guides since heat from the
bottom inverters (Filterpacks) can increase the
temperatures in the top inverters (Filterpacks), causing
inverter (Filterpack) failures.
When mounting multiple inverters (Filterpacks), fully take
caution not to make the surrounding air temperature of
the inverter (Filterpack) higher than the permissible value
by providing ventilation and increasing the enclosure
size.
Arrangement of multiple inverters (Filterpacks)
Heat generated in the inverter (Filterpack) is blown up from the
bottom of the unit as warm air by the cooling fan. When
installing a ventilation fan for that heat, determine the place of
ventilation fan installation after fully considering an air flow. (Air
passes through areas of low resistance. Make an airway and
airflow plates to expose the inverter (Filterpack) to cool air.)
