GROUND CONNECTION AT TB1-8
At TB1-8 on the Mother Board Rear Panel a ground wire should be connected. Ideally this wire
should go directly to the sub-station ground bar, if this is not feasible, shorting the wire to TB1-7
(Chassis ground) is an alternate method. This will cause surge currents to pass through the Mother
Board and chassis before exiting to ground. Connecting directly to the sub-station ground bar is
preferred.
