Xantrex Technology ENET-XFR3 manual Changing Internal Jumpers, Procedure for 1.2kW XFR

Installation and Configuration

Changing Internal Jumpers

Some of the settings on the Ethernet/RS-232 Interface card are user selectable by way of jumpers on the printed circuit board. The procedure for changing the jumpers varies depending on if you have a 1.2kW XFR, or a 2.8kW XFR.

CAUTION

If you remove the unit's cover, use proper static control techniques to avoid damage to static-sensitive components on the printed circuit board.

Procedure for 1.2kW XFR

Ensure that the input power connection has been disconnected and the unit is powered off before you attempt to remove the top cover. Remove all the screws holding down the top cover and then remove the cover. The printed circuit board that you need access to is upside down (component side down), so you must remove all the screws that are holding it in place. Refer to Figure 2-4to see which screws should not be removed.
