Installing the Logic Pcb

Following installation and wiring of the Backplane Pcb, the Logic Pcb is installed by plugging

it onto the two Backplane connectors. Aligning these connectors requires care and some

practice because you are working blind. Mis-aligning them can result in bent or broken pins.

Press the connectors firmly home without exerting undue pressure on the Logic PCB.

CAUTIONS

The Logic Pcb must only be installed or removed from the Backplane Pcb with the power

supply disconnected.

Take great care to ensure that the two connectors between the Backplane and Logic Pcbs

are correctly located. The L-shaped layout of the connectors is designed to assist with

correct location.

Once the two Pcbs are firmly mated, refit the M3 screw and washer.
