5.3.1 When the Output Terminal Is Not Grounded (Floating)
The output terminal of the PAT is isolated from the protective conductor terminal.
By connecting the GND wire of the power cable to the ground terminal of the
switchboard, the chassis of the PAT is set to ground potential as shown in Fig.5-3.
Pins 10 through 26 of the J1 connector on the rear panel (for external control and
output monitoring) are at approximately the same potential as the - (neg.) output
terminal of the PAT. Cables and devices that are connected to these pins must also
have an insulation capacity that is greater than or equal the isolation voltage of the
PAT.
