2.2 Mechanical Installation
This section outlines specifications, procedures, and the environment for proper mechanical installation of the
regenerative unit.
◆
Installation Environment
Install the regenerative unit in an environment matching the specifications in
performance life of the regenerative unit.
Table 2.1 Installation Environment
WARNING!
Fire Hazard.
When installing an IP00/IP20 regenerative unit in a closed panel or cabinet, sufficiently cool the panel or
cabinet with a cooling fan or air conditioner so that the air temperature entering the regenerative unit is 50
°
C or cooler. Failure to
comply could result in overheating and fire.
NOTICE:
Avoid placing regenerative unit peripheral devices, transformers, or other electronics near the regenerative unit as the noise
created can lead to erroneous operation. If such devices must be used in close proximity to the regenerative unit, take proper steps to
shield the regenerative unit from noise.
NOTICE:
Prevent foreign matter such as metal shavings and wire clippings from falling into the regenerative unit during installation.
Failure to comply could result in damage to the regenerative unit. Place a temporary cover over the top of the regenerative unit during
installation. Remove the temporary cover before regenerative unit start-up, as the cover will reduce ventilation and cause the
regenerative unit to overheat.
◆
Installation Orientation and Spacing
Install the regenerative unit upright as illustrated in
to maintain proper cooling.

Regenerative unit reliability improves in environments without wide temperature fluctuations.
When using the regenerative unit in an enclosure panel, install a cooling fan or air conditioner in the area to ensure that
the air temperature inside the enclosure does not exceed the specified levels.
Do not allow ice to develop on the regenerative unit.

Surrounding Area
Install the regenerative unit in an area free from:
• oil mist and dust
• metal shavings, oil, water, or other foreign materials
• radioactive materials
• combustible materials (e.g., wood)
• harmful gases and liquids
• excessive vibration
• chlorides
• direct sunlight.
