3.5 Serial Number Label
To determine if your drive is within the warranty time frame, find the bar code label or look in the lower
left of the technical nameplate. The serial number can be broken down as follows:
• yywwxxxx = yy ... year of manufacture
• ww ... week of manufacture
• xxxx....sequential number drive during that week.
3.6 Conduit Usage
The Vacon 50X drive in the IP66 enclosure is rated for 70 bar washdown from 15 cm. To keep this rating,
the use of a sealed conduit is required. The use of a Romex-type conduit will not prevent water entry into
the enclosure. If the approved conduit is not used, all warranty claims against water damage will be void.
3.7 Condensation
The washdown process of an Vacon 50X drive may create a temperature and humidity change in and
around the drive. If the unit is mounted in a cool environment and washed down with higher-temperature
water, as the drive cools to room temperature, condensation can form inside the drive, especially around
the display. To prevent this from happening, avoid using sealed connectors around rubbercoated cables
to seal the drive. These do not allow any air transfer and hence create a level of condensation and humid-
ity that exceeds the drive’s rating.
