Description
All grounding requirements applicable to a stand-alone PLC-3 or PLC-3/10 processor also applies to backup systems. In addition, you need to do the following:
When using a 1775-P1 power supply, connect the system common studs together on the power supplies of the primary and backup processors. Use 1-inch braid or 8 AWG wire.
If the primary and backup processors are in separate enclosures, connect the ground bus plates of the primary and backup processors together. Use 1-inch braid or 8 AWG wire.
Connect the ground bus plate of either the primary or backup processor, but not both, to earth ground.
Use star washers to assure a positive ground connection between metal surfaces and ground lugs.
The chassis I/O to backup processor switch (switch 8) must be ON so the backup processor can receive inputs from the I/O chassis. The backup processor will not be able to receive inputs from the I/O chassis if switch 8 is set incorrectly.
