Observe these additional cautions if taking the heatsink out of the panel from the opening in the control
D
panel to cool outside.
Install an oil-proof gasket on the fitting to prevent oil and dust from entering the unit.
D
Without a gasket, oil and iron particles may enter the control panel, corrosion of the electronic
parts and conductive parts may occur, and the resulting decrease of the insulation resistance may
result in a ground fault.
If oil is on the external cooling fan, decrease in the insulation resistance and in the life of the rotat-
D
ing section may occur over time.
Also, if oil and dust are on the heatsink, cooling efficiency may decrease due to the clogging of
the fins. Attach a filter onto the cooling-air intake and avoid taking in air in locations where the
oil mist is present.
To enhance the reliability of operation, the Inverter and Converter should be installed in an environment
free from extreme temperature increases. If the Inverter or Converter is installed in an enclosed environ-
ment, such as a panel, use a cooling fan or air conditioner to maintain the internal air temperature below
45°C (113°F).
Place a cover over the Inverter and Converter during installation to shield them from metal power produced
by drilling.
Always remove the covers from the Inverters and Converters after completing installation. Otherwise,
ventilation will be reduced, causing the Inverter and Converter to overheat.
The Inverter, Converter, and Motor must be stored under the following conditions.
Table 2.2 Storage Conditions
Temperature 0°C to 60°C (32°F to 140°F)
Humidity 5% to 95% with no condensation
The air at 40°C (104°F) with 50% humidity will condensate if the temperature drops to
28°C (82.4°F). Be sure that the place of storage does not have radical temperature changes.
Environment Indoors with no corrosive gas, mist, or dust.
