3.3.2 Changing the Ventilators
The device is to be separated from the network and is to be pulled out from the wall for changing the
ventilators. It is essential to wear an ESD-strap. The ventilators are in the initial part of the EPP-tube and can
be reached by removing the sealing plugs.
The identically constructed ventilators are interpolated sideways in the tube and can also be subsequently
easily extracted. It is to be thereby noted that all connection cable are separated before extraction and are
again connected during the reassembling according to the connection plan (refer to chapter 3.5.3).
