5.6 - MAINTENANCE
5.6.1 - Procedure after a long time storage
5.6.2 - Warranty
Opening of the housing will cancel the warranty.
5.7 - OPERATING ENVIRONMENT CONDITIONS
Cooling fluid temperature
5 % to 85 % without condensation
Clean air (pollution degree 2)
Drive must be protected against conducting dust
< 1 year: no restrictions
> 1 year: re-format the power capacitors
according to section 5.6.1.
MECHANICAL INSTALLATION CONDITIONS
The drive must be mounted on a stiff surface, in rooms or additional housings without hindering the
heatsink and the fan. The reliability may be increased by installing a cooling system (take care of
condensation).
Other installation conditions must be specially analysed and subjected to a technical specification in
agreement with INFRANOR.
Mechanical mounting
Vertical, on the cabinet rear wall.
Vibrations
Vibrations must remain within the limit values of the IEC 60721-3-3, class 3M1 standard for fixed
equipment.
After a long time storage, the leakage current of electrolytic capacitors increases dramatically.
In order to avoid any risk of damage or explosion, DC bus capacitors must be reformatted.
When the drive has been stored for 2 years or more, proceed as described below:
1. With a variable AC power supply, apply 25 % of the rated voltage on the mains input
during 30 min,
2. With a variable AC power supply, apply 50 % of the rated voltage on the mains input
during 30 min,
3. With a variable AC power supply, apply 75 % of the rated voltage on the mains input
during 30 min,
4. With a variable AC power supply, apply 100 % of the rated voltage on the mains input
during 30 min,
In order to avoid this procedure, the drive can also be powered at rated voltage every year
