Enhanced PLC-5 Programmable Controllers Prepare to Install the Controller Installing the controller is one part of setting up the hardware in your system. WARNING If you either insert or remove any module while backplane power is on, OR connect or disconnect any cable with power applied to this module or the device on the other end of the cable, an electrical arc can occur. This could cause an explosion in hazardous location installations.
Enhanced PLC-5 Programmable Controllers 11 Configure the I/O Chassis Configure the I/O chassis by doing the following: 1. Set the backplance switches. Pressed in at top ON (closed) Pressed in at bottom OFF (open) Switch 1 on O1 N O F F off 2 3 Always Off Last State 1 Outputs of this I/O chassis remain in their last state when a hardware failure occurs. 1 Outputs of this I/O chassis are turned off when a hardware failure occurs.
