Drive converter cabinet units
Operating Instructions, 10/2008, A5E00288214A
461
Description
The average service life of the device fans is 50,000 hours. In practice, however, the service
life depends on other variables (e.g. ambient temperature, degree of cabinet protection, etc.)
and, therefore, may deviate from this value.
The fans must be replaced in good time to ensure that the cabinet unit is available.
Preparatory steps
Disconnect the cabinet unit from the power supply.
Allow unimpeded access.
Remove the protective cover.
Removal steps
The removal steps are numbered in accordance with the figure.
1. Remove the busbar (6 screws).
2. Remove the retaining screws for the fan (3 screws).
3. Disconnect the supply cables (1 x "L", 1 x "N").
You can now carefully remove the fan.
CAUTION
When removing the unit, ensure that you do not damage any signal cables.
Installation steps
For installation, carry out the above steps in reverse order.
CAUTION
The tightening torques specified in the table "Tightening torques for connecting current-
conducting parts" must be observed.
Carefully establish the plug-in connections and then ensure that they are secure.
The screwed connections for the protective covers must only be tightened by hand.
