There will be clearances between adjacent modules when the extended temperature range base unit is used, and therefore
modules should be mounted using the white lines on the circuit board as markers.
Mount the module occupying two slots as shown below
• For the CPU module, align the long edge of the white line on the circuit board with the left side of the module, and then
mount on the base unit.
• For the modules other than the CPU module, align the short edge of the white line on the circuit board with the left side of
module, and then mount on the base unit.
