INSTALLATION INSTRUCTIONS
Each G3USB option card comes with a cable for communications from the
main G3 operator interface PC board. It also comes with three screws for
attaching the option card to the inside of the G3 operator interface’s rear cover.
To install the option card remove all power and communication cables from
the unit. The chassis ground connection to the rear cover may be left connected.
The G3 operator interface literature contains instructions for removing the rear
cover, refer to the “Battery & Time Keeping” section.
Using the three screws provided connect the option card to the rear cover as
shown in Figure 1.
Connect the cable from the option card to CN11 on the main board of the G3
operator interface as shown in Figure 2. Be sure both ends of the cables are
firmly seated into their appropriate connector housing.
Carefully replace the rear cover by reversing the previous instructions for
removing the rear cover.
Caution: The option and main circuit boards contain static
sensitive components. Before handling the cards, discharge
static charges from your body by touching a grounded bare
metal object. Ideally, handle the cards at a static controlled clean
workstation. Also, handle the cards by the edges only. Dirt, oil,
or other contaminants that may contact the cards can adversely
affect circuit operation.
Warning: Depending upon the G3 operator interface, high voltage
may be present inside the operator interface. Be sure to remove
all power before removing the rear cover of the operator interface.
