POWER ADJUSTMENTS
If necessary, remove the power tap selection wire
(white wire) and reattach it to the desired power
tap. The numbers on the terminal strip indicate the
output in watts for a 70-volt paging system (on a
25-volt paging system, the output will be approxi-
mately 1/8 of that indicated (see Table 1)).
Reassemble the two halves of the speaker case
by reinstalling the eight bolts.
CONNECTION TO AMPLIFIER
Exercise special care in removing back cover of
explosion proof driver enclosure (Part 1) to avoid
damaging machined surfaces. Prior to reassem-
bly, make certain that joining surfaces of enclo-
sure are free of dirt. Tighten all cover bolts
completely. To provide the specified protection in
hazardous locations, please note that no com-
pound of any type is to be applied on machined
flange.
