3.2.3 Location
Installation of multiple products
Keep sufficient space between products so that the air vented from one
product will not be taken in by other products.
Installation at indoor site (for air cooled type)
1. For a facility having a large installation area (that can vent the air
naturally):
Make an air outlet on a wall at a high level and air inlet on a wall at a low
level, to allow for adequate airflow.
2. For a facility having a small installation area (that can not vent the air
naturally):
Make a forced air exhaust vent on a wall at a high level and an air inlet on a
wall at a low level.
3. Using duct to exhaust the air:
In case the indoor site cannot accept the exhausted air from the product
or/and is air conditioned, ventilate by installing a duct on the outlet
ventilation of the product. Do not fasten the duct on the outlet ventilation of
the product directly. Have the space at least the duct’s diameter apart. Use
a fan for the duct that considered the ventilation resistance of the duct.

Do not install in a location which can be subjected to any of the
conditions in “3.2.1 Environment”.
The air cooled product radiates heat from the air vent of the cooling fan.
If the product is operated with insufficient air ventilation the internal
temperature can exceed 45
o
C, which can cause and affect the
performance and life of the product. To prevent this ensure that
suitable ventilation is available (see below).
