b.
Plug power supply into a wall socket. (CHUCK
comes with a universal power supply that will
operate on 120 VAC 60 Hz power or 240 VAC 50
Hz power.)
3.
Ground the CHUCK Brain.
a.
Connect ground wire to grounding stud on
CHUCK Brain (shown, right).
b.
Connect opposite end of ground wire to an
appropriate grounding point. The ring terminal is
sized for the #10 machine screws that are used
to mount the CHUCK Brain. We recommend you
ground at one of the mounting screws.
IMPORTANT: CHUCK box MUST be grounded to a point that is electrically connected to the
flange containing the instrumented bolts. Failure to establish a ground connection will result in
erratic bolt stress readings.
Installing CHUCK to Your Bolting Skid
Both the CHUCK Brain and its companion server can be attached to your skid.
If you’ve fabricated your skid according to the spec provided by Hex Technology, there will be
mounting brackets for both the CHUCK Brain and Server.
