Siemens SINUMERIK 828D Series User Manual

Boundary condition
It is important that the reinforcement plates must always be installed when operating the S120
Combi with the external fan unit:
WRONG:
S120 Combi and external fan unit without rein‐
forcement plates
CORRECT:
S120 Combi and external fan unit with instal‐
led reinforcement plates
Note
Shutdown as a result of excessively high temperature if the reinforcement plates are missing
Operation without the reinforcement plates is not permissible.
If the reinforcement plates are incorrectly fixed, this can result in an excessively high heat sink
temperature and cause the S120 Combi to prematurely trip.
4.10.13 This is how you clean the heat sink of the S120 Combi
Cleaning the heat sink
The S120 Combi heat sink should be cleaned at regular intervals using either compressed air
or high-pressure water jets. To clean the heat sink, the air baffle plate at the rear of the S120
Combi must be removed.
