Instruction manual

The right subpanel has a liquid crystal display and a REMOTE lamp.

The liquid crystal display shows the numeric value of all programmed output parameters. It

also shows all error messages and measured values.

The REMOTE lamp illuminates when the AC power system has been addressed through the

IEEE-488 interface (GPIB).

3.4. REAR PANEL CONNECTIONS

(Refer to Figure 3-2 for all rear panel connections.)

3.4.1. POWER INPUT

TB1 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 4 is the chassis connection which should be

connected to the input mains ground.

3.4.2. POWER OUTPUT

TB3 is the power output terminal block. Refer to Table 3-1 for identification of the TB3

terminals. Refer to Figure 2-2 for the output of all multiple power source power systems.

Table 3-1: Terminal Identification

TB3 DESCRIPTION

1 Phase A Output HI

2 Phase B Output HI

3 Phase C Output HI

4 Output Neutral

3.4.3. EXTERNAL SENSE

TB2 is the external sense input connector. The external sense input of the master power

source must be connected to the respective AC Power System output. If the inputs are not

connected, an OUTPUT FAULT error message will be generated. Table 3-2 identifies the

pins of connector TB2.
