The cables to the terminals on the motherboard are run through the two side chan-

nels from the bottom or from the top.

On the PCD2.M170 and the PCD2.M480, the terminals on the motherboard are ac-

cessible without removing the cover.

Following these rules will ensure that the LEDs are visible and the bus connections

remain accessible.
