GENERAL ARRANGEMENT
All cable glands should be of an equivalent NEMA/IP rating to that of the unit
and integrated with the unit such that this rating is maintained.
Once termination is complete, carefully push the cover back onto the unit, avoid-
ing damage to the mating surfaces. Tighten the 6 off cover screws evenly, to
ensure maintenance of the required gap between the cover and enclosure.
3. OPERATION
The unit is initiated directly from the power source.
For all versions, a 5-way DIL switch selects the tone required from the list shown.
The DB3P includes two 5-way DIL switches to select any two tones from the list.
These units can be switched between any two of the tones listed by either:-
· Reversing the polarity of the power supply, or
· By a 3 wire common +ve system, switching between the two –ve lines.
