Installing the Control's Circuit Board
To install the circuit board in the cabinet, perform the following steps:
Step Action
1
Install the nylon standoffs (supplied) into the top corner holes of the mounting plate (Figure 3-3, Detail A.)
Insert the top of the circuit board onto the two standoffs at the top of the mounting plate.
2
Place the board flat and secure to the mounting plate with the three accompanying screws and spacers as
shown (Detail B.)
NOTES:
• Make sure that the mounting screws are tight. This ensures that there is a good ground connection between the PC
board and the cabinet.
• Dress field wiring away from the microprocessor (center) section of the PC board. Use small holes in the sidewalls of
the cabinet for anchoring field wiring using tie wraps (Figure 3-3).
