7 Maintenance
To ensure the proper operation of products, maintenance tasks and periodical visual
inspections are required.
The products have been designed for permanent and unsupervised operation. Neverthe-
less you have to perform checks every now and then. When doing so, you can detect and
remove dirt in the vicinity of or within equipment racks, so the air supply and heat dissipa-
tion of the products is always ensured.
The current status of the hardware components can be monitored via a connected
NMC-511 FaultManager. For more information on the NMC-511 FaultManager, please
refer to the product documentation of the NMC-511 FaultManager.
7.1 Maintenance tasks
Soiling may impair the air supply and the heat dissipation and thus affect the operation.
For this reason, the activities listed below should be performed in the interval specified.
Maintenance tasks
Task/s Interval/s
Replace the fan after 30,000 operating hours
Replace the air filter pad Depends on the environmental conditions
Early fan replacement
Independent of the ambient data at the installation site, the fan may have to be replaced
earlier. For this reason, please comply with the following recommended visual inspec-
tions and intervals.
7.2 Periodical visual inspections
The table below lists the recommended tasks for maintaining the products. The visual
inspections should be performed in the intervals specified to be able to respond in due
time, e.g. in the case of changes at the location that may result in improper operation.
We recommend logging the results of the test.
