Dual Switch
This configuration uses two cables. One connects the Preva to the first switch
and the other connects the first switch to the second switch.
1. Route one cable from the Preva to the first switch location either through
conduit or on the surface of the wall.
2. Route the other cable from the first switch location to the second switch
location either through conduit or on the surface of the wall.
3. Thread the first cable end with the handset connector through the opening in
the wall mount cover from the inside and connect it to the Operator Panel. If
the cable is routed on the surface of the wall, it should enter the wall mount
cover through the notch on the left of the power switch.
4. For a parallel connection, connect the cable conductors of both cables to
terminal block J1 on the PCB of switch enclosures #1 as shown in Figure 44
.
The (2) indicates that two green wires will join together in terminal 1 of J1,
etc. For a series connection, connect the wires as shown in Figure 45.
