Electrical connection
Two fittings are provided on the left side of the enclosure: the AC Power bulkhead fitting for power cable, and
the M300 TOC patch cable connection. Feed the power cable through the bulkhead fitting on the side-wall.
AC power connections are positioned on the right side of the printed circuit board. See Figure 3 for terminal
wiring. Ensure line fuse is properly installed. See product label for specified fuse size.

Introduce Sample Flow
Close the inlet needle valve by turning the adjustment knob fully clockwise. Slowly open the sample point
isolation valve, then slowly open the needle to start flow to the sensor. Allow approximately 3-5 minutes
for the sensor to fill, and observe flow at the drain tube. Once there is flow, check that there are no leaks
inside the sensor enclosure. With the needle valve fully open, allow the sensor to initially flush with sam-
ple water (4-24 hours is recommended). Close front cover and connect the M300 TOC patch cable to the
connector on the bottom left side of enclosure.
