QC-300 Series User’s Guide
Assembling the mounting stand
The QC-300 is secured to the swivel slots of the mounting stand by a shoulder
screw, a cap screw and associated washers.
Assemble the QC-300 to the mounting stand as shown.
Tighten the shoulder screw (1), and then tighten the cap
screw (5) and washers (3 & 4) so that the QC-300 will
be secure when adjusted to the desired tilt position.
Safety considerations
The QC-300 is completely enclosed and no hazardous out-
puts can come in contact with the user. Safety considerations
are related to power connections and physical mounting.
WARNING
If the QC-300 falls from its mounting location, serious personal injury or damage to
the equipment can result.
Power cord and plug
Do not locate the power cord where it can be walked on or will create a tripping hazard. Connect the 3-wire
power plug to only a 3-wire grounded outlet. Never connect 2-wire to 3-wire adapters to the power cord
or remove the third ground wire to fit the plug into a 2-wire electrical outlet. Modifying or overriding the
third-wire ground creates a safety hazard and should not be permitted.
DANGEROUS VOLTAGE
Always disconnect the power cord from the source of AC power before unplugging
it from the QC-300 power connector. The AC voltage available at electrical outlets is
extremely dangerous and can cause serious injury or death.
Electrical wiring and connections
Perform regular inspections of all connections to the QC-300. Keep connections clean and tight. Locate
cables away from moving objects. Do not create tripping hazards with power cords, input/output cables or
other electrical wiring.
Use shielded cables to connect to the serial RS-232 port. Make certain that cables are properly terminated
and firmly connected on both ends.
