7.3 Periodic maintenance
Operational lifespan of electronic components are closely related to
using environment, using condition and maintenance situation.
Lifespan of vulnerable parts under normal using conditions are as
shown in Table 7-2.
Table 7-2 Replacement time of components
Component name
Lifespan
Cooling fan
2~3 years
Capacitor 4~5
years
PCB 5~8
years
Periodic service conditions of above components are:
1. Ambient temperature: 10~35
℃
;
2. Load coefficient: 85% below;
Users determine replacement period according to actual situation.
7.4 Storage
1. Store cabinets in well-ventilated places, and avoid high
temperature, humidity and dustiness;
2. Long time storage will lead to deterioration of electrolytic
capacitors. So ensure connection the cabinet to power supply at least
once in two years. And input voltage slowly raises rated value by the
voltage regulator.
