Fixed cable connection
The Yi8 and Yi12 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. Remove the knockout opening in the cover plate
[1] and
attach the rubber grommet
[2] correspondingly.
2. Insert the connection cable through the rubber grommet.
3. Undo the four screws of the connector panel.
4. Connect the cable wires to the screw terminal.
Þ
Observe the correct polarity!
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 all screws.
