Installing Cable to SL220 Frame
CAUTION: Failure to properly tension cables (J1) may
result in damage to ceiling tile framework.
1. Thread each cable (J1) completely through cable lock (J2),
corresponding hole in corner of SL220 frame (B), and
completely through opposite side of cable lock (J2) (See
Figure 8).
2. Adjust cable tension until SL220 frame (B) is supported
entirely and evenly by all four support cables, but not so
tight as to distort ceiling tile framework.
CAUTION: Cable lock (J2) will allow cable to enter from
only one direction per side, indicated by arrows on lock.
Depress spring loaded pins on cable lock (J2) to release
cable tension.
