6K-ERB08 User's Guide Installing the 6K-ERB08

Caution! Be careful not to pinch the cable when you replace the cover — if this cable is cut, the resulting

short circuit can damage the computer.

Connect the other end of the power cord to the connector labeled

PC POWER connector (P18) on the 6K-

ERB08.

Set the POWER IN jumper (JP1) for +5PC.

External +9V AC power adapter connections

You can power the 6K-ERB08 using the AC power adapter (MCC part number CB-PWR-9). This adapter

provides 9 volt, 1 amp DC power, 110 VAC power. To connect the AC adapter, do the following.

Turn off power to the computer.

Connect the CB-PWR-9 cable to the

9V EXTERNAL POWER connector (P19).

Plug the AC adapter into a power outlet.

Configure the POWER IN jumper (JP1) for 9V EXT.

Relay logic

Use jumper JP2 to select inverting or non-inverting logic to control the relays. Refer to for the

location of this jumper. The relay logic jumper is shown here configured for NON-INVERT (digital high). This

is the default position.

 When set to non-invert, the relay activates when the DIO signal is high (1), and becomes inactive

(non-energized) when the DIO signal is low (0).

invert, the relay activates when the DIO signal is low (0), and becomes inactive

(non-energized) when the DIO signal is high (1).
