Nrill Safety Clip

The cabinet and the grill both have a small loop of plastic line. The 
grill’s loop has a clip attached. Using the grill clip, attach the grill to 
the cabinet’s loop. This will help prevent the grill from falling should 
it become detached.

2. 

Secondary Support Tab

Loudspeakers can potentially generate substantial vibration. In 
addition to ensuring all hardware is properly installed and secured, 
you must use the secondary support tab on the enclosure to secure 
the loudspeaker to an appropriate structural support. This will 
minimize the chance of the loudspeaker falling from the ceiling 
in the event the primary mount fails. Any cable or wire used as a 
secondary support line must be strong enough to support several 
times the weight of the loudspeaker. Do not use rope, string, twine 
or other textile-based line in the secondary support system as it is 
easily cut or burned. The secondary support attachment point and 
any fasteners used on the building’s structure must also be strong 
enough to support several times the weight of the loudspeaker.

Refer to 

— Figure 4

Connections 

Connect signal wires either directly to ceramic terminal block noting correct polarity or to 
the supplied plastic terminal block assembly. W hen using the plastic terminal assembly, 
connect the four pin receptacle to the ceramic block observing polarity. Connect the signal 
wires to the screw terminals of one of the two pin plugs observing correct polarity. The 
other two pin plug can then be used as pass through to daisy chain the signal to another 
speaker or it can be left unused.
