Connect the riser cables to TB5 in the desired style,
using 18-14 AWG twisted, shielded pair. The other
ends of the risers connect to the OCC-1 terminal
block. Refer to the OCC-1 Installation Instructions,
P/N 315-090918, for further details.
For connections to other connectors and terminal
blocks, refer to the appropriate module installa-
tion instructions. (See also Figure 3 or Figure 4,
as appropriate.)
CAUTION: Keep the riser cables away from the AC power lines, the 24 VDC
supply lines, and the wires carrying the amplified audio signals.
