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 ventilated,
in order to avoid overheating.
perforated plate
In the case of several module subracks mounted on top of one
another, we recommend removing the perforated plates from
between the module subracks, and inserting a rack-mounted
fan underneath the module subracks.

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 application requirements:
