Wall Mounting
Optional metal and plastic enclosures are available
to mount the Model 330 to a wall when no other
enclosure is used. The enclosure is first attached
to the wall using fasteners through its mounting
holes.
After wiring, the transmitter may be attached to the
enclosure with the terminal headers facing in using
the slots in the mounting flanges. As an alternate
mounting arrangement, the Model 330 may be
fastened to the box cover using double-sided
adhesive tape.
Electrical Installation
All connections to the Model 330 are made to screw
terminals on removable headers.
Power Supply Wiring
The Model 330 requires 12-24 Volts AC or DC to
operate. The power connections are made to the
ORANGE header. The connections are labeled beside
the header. Observe the polarity shown on the label.
If a Data Industrial plug in type power supply
(A-1026 or A-503) is used connect the black/white
striped wire to the terminal marked positive (+) and the
black wire to the terminal marked negative (-).
Note:
Included with every Model 330 is a 330IK kit
containing a screw, lock washer and ground lead to
connect the Model 330 to Earth Ground. This will
help prevent electrical interference from affecting the Model 330s normal operation.
