6 .1 Installation
The BGT can be installed in any position.
Install in clean environment ensuring enclosure IP 54 or
higher, whereby no condensation is permitted.
It must be ensured that the module subrack is well ven-
tilated, in order to avoid overheating.
perforated plate
In the case of several module subracks mounted on
top of one another, we recommend removing the per-
forated plates from between the module subracks, and
inserting a rack-mounted fan underneath the module
subracks.
6 .2 Old-new PFA exchange
When exchanging the old PFA 700 (Order No. 8 439
510 0) for the new PFA 700, the mains voltage on the
new units must be selected in accordance with the ap-
plication requirements:

A PROFIBUS plug connector with an internal additional
EMC protective circuit will be delivered with the new
PFA 700 when ordered as a replacement for the old PFA
700. If the new PFA is operated in an old module sub-
rack with the Order No. 8 440 228 3, this plug connec-
