3. Installation
Perform the installation of the enclosure in accordance with the following items.
3.1 Preparation Prior to Installation (Selecting a Location)
Install the enclosure in the following sort of location:
1. The location should be 1000m or less above sea level.
2. The ambient temperature should be between -5~40ºC.
• The location should not trap hot air from the enclosure.
• The room ventilation should be good. Poor ventilation can lead to a rise in
ambient temperature due to heat sources such as the unit itself.
3. The location should be free from corrosive gases or ocean spray which promote
rust and corrosion.
4. The location should be free from dripping of, or contact with, water.
Pay attention to the following when installing indoors.
• If the roof is a metal or glass type, there is a risk of water dripping from con-
densation.
• Water may drip from leaks in pipes.
• There is a risk of the enclosure contacting water if it is installed on concrete
that has not been thoroughly dried (particularly in the basements of buildings).
If this is the case, place a space heater within the enclosure and always keep the
internal temperature higher than the outside air.
5. The location should be free of dust or grime.
A dusty or dirty location runs the risk of degrading the contact of the contactors as
well as damage to the insulation.
6. The location should be free of vibration or shock.
7. The location should be free of explosive or flammable gas.
8. The location should have space for cleaning, inspection, and testing.
Always maintain this space. (Minimum front and back spaces are also regulated in
fire codes.)
3.2 Leveling
The floor surface of the enclosure installation location should be level to within ±3mm
across 1m

3.3 Linking of Enclosures (Row Enclosures)
When using row enclosures, link the together using joining bolts. There are four fastening
locations on each end of the enclosure. Always make sure that the front of each enclosure
is straight, and the enclosure does not fall over (
Figure 3.1 ).
The linking method differs between linking the same enclosures, and linking with other,
general, enclosures (
Figure 3.2 ).
