7.4 Relay Board Installation
I MPORTANT: Components are static sensitive. Take ESD precautions - use a wrist
grounding strap
Materials needed for option board installation:
· Relay option board
· Connector panel for Relay option board
· Screws (4)
· 4-40 x 1/4" screws (2)
A phillips head screw driver is needed to install the relay option board.
1. Disconnect all cables from the Model 2002.
2. For the installation of an option board you must have access to both the front and rear of
the Model 2002. Remove the instrument from its mounting panel if necessary.
3. Remove the option blanking panel from above the power inlet module on the rear panel.
Replace it with the relay board connector panel supplied in your upgrade kit. Install the
panel so that the text on the panel is oriented to the top and bottom of the unit.
4. Un-snap the bezel from the front of the case. Remove the four screws from the front panel,
then carefully remove the front panel.
5. Insert the relay option board (screw heads on the terminal strip should be closest to the top
of the Model 2002 case) into the back panel using the supplied 4-40 x 1/4" screws.
6. Connect the ribbon cable of the option board to the I/O port (P1) on the main PC board.
The brown wire of the cable denotes pin one and should be installed toward the front of the
case.
7. Reattach the front panel (take care not to kink the ribbon cable). Snap the bezel onto the
front of the case.
