The Lifetime of Machinery Parts

DC Bus Capacitor
DC bus capacitor will be deteriorated by the affection of ripple current. Its lifetime is
determined by the surrounding temperature and operating conditions. If it is operating in an
air-conditioned site, its lifetime can be up to 10 years.

Relay
The contact will be worn due to power-on or power-off which leads to poor contact. The
lifetime of relay is influenced by the power supply capacity; thus, the accumulative time of
turning on or off the power is about 100,000 times.

Cooling Fan
In continuous operation, the lifetime of the cooling fan is 2 to 3 years and it has to be
replaced then. However, if there is any unusual noise or vibration during inspection,
replacing a new one is a must.
