1. Series E50 Speaker models have in-out wiring
terminals that accept two #12 to #18 American
Wire Gauge (AWG) wires at each screw
terminal. Strip leads 3/8 inches and connect to
screw terminals.

circuits to assure integrity of circuit
supervision as shown in Figure 2. The polarity
shown in the wiring diagrams is for operation
of the appliances.
