Ground jumper setting
The backplane of the Wall-Mount Chassis is equipped with a jumper setting, W1,
that allows the output to be configured as floating, negative voltage or positive
voltage referenced to ground. The unit is set at the factory to provide negative
voltages (-24 Vdc/-48 Vdc) for Teleline/TeleLite installations.
The configurations are well indicated on the backplane at the different locations
where W1 can be installed.
