INSTALLATION
The sensi!ve axis of the transducer can be oriented in any direc!on. To ensure clean response
to high frequency vibra!ons, the transducer must be securely mounted to a flat machined
surface using four #6 (or 3mm) socket head screws. If a bracket is required, it should be of
rigid construc!on to prevent spurious mechanical resonances in the pass band.
WIRING
In ordinary, nonhazardous loca!ons the transducer should be wired according to Page 4
(drawing 7623, Sheet 2).
In hazardous loca!ons the wiring method depends upon the area classifica!on.
1. In Class I, Div 1, Groups A, B, C & D or IEC Zone 0, Group IIC hazardous loca!ons, the
transducer may be connected through a zener diode safety barrier to the safe area
receiver in accordance with Page 5 (drawing 7623, Sheet 3).
2. In Class I, Div 2, Groups A, B, C & D loca!ons the transducer may be wired as in (1), or it
can be wired without a safety barrier if wired in accordance with Page 6 (drawing 8096).
