1.10.2 Detector Assembly To RF Strap Installation
WARNING - Risk Of Electric Shock
Ensure all RF power has been disabled before any work
is carried out on the tool.
1
Remove the tool panel cover to expose the RF transmission strap or rod.
2
Determine where on the RF strap or rod the Detector will be located. Because
the tool panel cover will need to be opened approximately 76 mm (3 in.) to
access the Detector Assembly to Converter connection (see
Figure 1-8 on
page 1-14 ), the interface between the Detector and RF strap/rod (see Figure
1-4 on page 1-8 ) must be within 203 mm (8 in.) of the Converter mounting hole
(see section 1.10.3 on page 1-9 ). If it is required that the tool panel cover be
opened more than 76 mm (3 in.), the distance between Detector and Converter
must be decreased accordingly.
3
Determine the orientation of the clamp when connecting the Detector Assembly
to the RF strap or rod. (See
Figure 1-4 .)
4
With the Detector and clamp surrounding the RF strap or rod, insert two thumb
screws through the Detector and then turn the screws into the clamp until finger
tight. (See
Figure 1-4 .)

5
If the detector is to be installed on a strap that has a bend causing the strap to
run along the side of the detector, or if the cable must be routed close to high
voltage, the minimum distance between the sensor and cable and any point of
high voltage must be 1 in. (25.4 mm). See
Figure 1-5 .
