Chapter 9 Maintenance
Lots of factors such as ambient temperature, humidity, acid/alkali substances,
dust, vibration, internal component aging and wearing may raise the chance
of the occurrence of potential faults. Therefore, it is quite necessary to
conduct daily checking and periodical maintenance to the drives that are
operated or stored.
If the drive is transported from a distant place, routine inspections such as
integrity of components and tightening of screws must be done before using
the drive.
During normal operation, clean the dust inside the drive periodically, and
check if the screws become loose.
If the drive has not been used for a long time, it is recommended to energize
it every six months for more than half an hour to keep the internal electronic
elements in good conditions.
For the drive that has been stored for more than two years, when
supplying AC power to the drive, use a voltage regulator to raise the
input voltage to rated input voltage gradually, otherwise the drive may
be damaged
Danger
!
During drive's operation, the voltage is very high. Misoperation may
result in serious personal injuries.
Within a certain period of time after the power is cut off, dangerous
high voltage still exsit inside the drive.
Maintenance of drive shall only be done by qualified, trained
professionals.
Before maintenance, maintenance personnel must take off personal
metal articles such as: watches, rings. Working uniforms and tools
used during the operation must satisfy insulation requirements to
avoid electric shock.
