Fixed cable connection

The 10A and 10A-D loudspeakers are each supplied with a cover

plate [1] and a rubber grommet feed through [2]. For indoor

operation, these items can be used to hide the connector panel, if

required. For unprotected outdoor operation, the connector panel

must be covered, i.e. both items must be used to achieve an IP

degree of protection of IP34.

To install the fixed cable connection, proceed as follows:

Tools required: Philips screw driver (#PH2).

1. Prepare the rubber grommet and the connection cable.

2. Remove the knockout opening in the cover plate and attach

the rubber grommet correspondingly.

3. Insert the connection cable through the rubber grommet and

connect the cable wires to the screw terminal.

Þ Observe the correct polarity!

4. Undo the four screws of the connector panel.

5. Push the cover plate towards the connector panel until it fits

into place.

6. Finally fix the cover plate together with the connector panel

using the four screws.
