• All output lines are wired to a common line inside the intrinsically safe equipment (one common line per intrinsically safe circuit).

• All input lines are wired to a common line outside the intrinsically safe equipment (one common line per intrinsically safe circuit).

• Each output line of the EB3L makes up one independent intrinsically safe circuit of a pilot light or buzzer.

• The following example illustrates the wiring for a total of 10 contacts used by three illuminated

(A maximum of 16 channels of EB3L and EB3C can be wired to a common line.)

EB3P consisting of one

enclosure

One intrinsically safe circuit

(16 circuits maximum)

Note:

When using two or more EB3L's

to set up one intrinsically safe circuit

in the common wiring configuration,

interconnect two neutral terminals

(N1 through N10) on each EB3L

between adjacent EB3L's in parallel.
