5.2. When Bridge Connection is Required
Step 1. Strip the speaker cable jacket as shown at right.
Step 2. Detach the rear case.
Remove the 4 screws holding the rear case.
Note
Gaskets are used to seal the unit’s rear case and screw holes. Since
these must be used again when reattaching the rear case, take care
not to lose or damage them.
Step 4. Mount the cable gland to be added.
Notes
• Prepare the cable gland of PGB9-09 size separately.
• Ensure that the cable gland is securely tightened. If loosely tightened,
water may get inside the rear case.
Step 5. Run one each of speaker cables through the cable gland.
Step 6. Connect the speaker cables with the same polarity to each terminal
according to the polarity indication at the screw terminal.
Step 3. Punch a knockout hole.
Punch out the knockout on the rear case by tapping the center
of the knockout with a screwdriver or other tool.
Note
Clean burrs off the knockout hole after removing the knockout.
If the cable gland is attached with the burrs left in the hole,
water may get inside the rear case.
