A HIGH RANGE lamp illuminates when the AC Power System is programmed to the high voltage range.
An LCD digital display shows the numeric value of all programmed output parameters. It also shows all error
messages and measured values.
A REMOTE lamp illuminates when the AC Power System has been addressed from the IEEE-488 interface.
3.4 REAR PANEL CONNECTIONS
(Refer to Figure 3-2 for all rear panel connections.)
3.4.1 POWER INPUT
TB3 is the terminal block for the 3-phase input voltage. Terminals 1, 2 and 3 connect to each leg of the 3-phase input.
Terminal 5 is the chassis connection which should be connected to the input mains ground.
3.4.2 POWER OUTPUT
TB1 is the power output terminal block. Refer to Table 3-1 for identification of the TB1 terminals. Terminal 3 and 4 are
used for a 1-phase system. Refer to Figure 2-2 for the output of all multiple power source power systems.
TB1 DESCRIPTION

3.4.3 EXTERNAL SENSE
J6 is the external sense input connector. The external sense input of the master 4500L must be connected to the
respective AC Power System output. If the inputs are not connected, an AMP FAULT error message will be generated.
Table 3-2 identifies the pins of connector J6.
