Mechanical design

Installation of the Active Interface Modules:

The filter modules of the Active Interface Modules have to be mounted to the backside

of a mounting plate (resp. to mounting rails), in correspondence with their fixing holes.

The mounting plate / mounting rails can be mounted to the backside of the cabinet, as

shown in Fig. 1. If installation of the mounting plate / mounting rails to the backside of

the cabinet is not possible, spcial attention has to be paid on a stable mounting of the

mounting plate / mounting rails (see Fig. 2).

Additionally, a fixation of the filter module will be required in the front zone. For that,

the laterally provided fixation bores with diameter 7mm can be used.

The reactor of the Active Interface Module is prepared for installation underneath the

filter module. The reactor has to be mounted underneath on a mounting base or

mounting plate, acc. to their fixation holes. A stable setup and a uniform load

distribution over a large area are essential, owing to the mass of the reactor.

Therefore, the reactor support area on the mounting base or mounting plate on the

reinforced cabinet frame should be as large as possible.

An additional fixation of the reactor in the top zone, with a stable fixation in the bottom

ares is not required .

Screws and tightening torques

For fabric-base laminates, synthetics, aluminium, copper, captive nuts, welding nuts,

blind rivet nuts, rivet nuts and hard materials (steel), screws of strength class

≥ 8.8 have to be used.

Insofar, as there are no differing specifications mentioned in the technical

documentation, the tightening torques indicated in table 1 shall apply for electrical

and mechanical connections.
