Fixed cable connection
The 27S-SUB and 27A-SUB 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.
