2. Mounting and installation of the <strong>VSA</strong> drive<br />
2.1 Environment<br />
The environment will directly affect the proper operation<br />
and the life of the VSD, so install the VSD in an environment<br />
that complies with the following conditions:<br />
Ambient temperature: 14 to 122F (-10 to 50C)<br />
Avoid exposure to rain or moisture.<br />
Avoid smoke and salinity.<br />
Avoid dust, lint fibres, and metal filings.<br />
Avoid electromagnetic interference (soldering machines, power machine).<br />
Avoid direct sunlight.<br />
Avoid corrosive liquid and gas.<br />
Keep away from radio active and flammable materials.<br />
Avoid vibration (stamping, punchpress). Add a vibration-proof pad if the situation can not be avoided.<br />
If several VSDs are placed in the same control panel, provide heat remoual means to maintain the temperature below 50C.<br />
See figure 3-1 for proper drive arrangement.<br />
