3.2 Wire the CPU Power Connector and Tamper Switch
CAUTION:
UNPLUG CONTROLLER FROM POWER OUTLET. Do not attempt to wire the connectors while
the power supply is “hot”. Wiring a controller while it is “hot”
can cause electrical shock, serious
injury, death, damage to equipment, or system failure.
OBSERVE POLARITY! Failure to obey polarity can cause electrical shock, injury, death, equipment damage.
1.
CPU Power connection:
Use the 2-pin orange connector supplied with CPU.
a)
The CPU connectors will always install in the topmost slot –
you will notice the Tamper switch is spliced
into the ground wire of the power harness where the CPU will be installed
.
b)
Connect the Black (GND) wire from the Controller Power Harness to pin-2 of the power connector.
Connect the RED (+12 VDC) wire from the Controller Power Harness to pin-1 of the power connector. .
2.
Wire the CPU Tamper connection:
Use the 4-pin orange connector supplied with the CPU board
a)
Wire the Tamper switch to Pin-3 of the Tamper Connector.
b)
NOTICE that the Tamper Switch is already spliced into the Ground (BLACK) Wire from the Controller
Power Harness.
