    Installation TW 5250 • TW 3500 • TW 1750 The output power and sense leads should be shielded and the shield connected to the chassis to prevent noise pickup (or radiation to sensitive circuits in the vicinity). Again, the shield should be connected to chassis ground. Due to the high voltages present, 312 VRMS line-to-neutral and 437 VRMS line-to-line cables rated to these voltages must be used for both the Power and Sense leads.
  • Page 35: Table 2-8 Recommended Wire Gauge Selection Guide

    TW 5250 • TW 3500 • TW 1750 Installation In high performance applications, as in motor start-up and associated inrush/ transient currents, additional consideration is required. The cable wire gauge must consider peak voltages and currents that may be up to ten times the average values. An underrated wire gauge adds losses that alter the inrush characteristics of the application and thus the expected performance.

If two TW supplies are “chained” (multiple TW units connected in a Master/Slave configuration), the system ampacities are multiplied.
  • Page 64 Operation TW 5250 • TW 3500 • TW 1750 Place the master TW into master mode by either setting the mode up in the menu system or through the SCPI system. SCPI: • If there are two slaves, GPIB Send to the master: SYST:CHASSIS 3 The chassis number counts the master chassis as one of the chassis.
  • Page 65 TW 5250 • TW 3500 • TW 1750 Operation Now turn off the TW while it reads “Sys Restart” or after the display reads “Chained n”. Re-run steps 7 through 9 for each slave, incrementing the slave address each time. The TW unit output and master sense conductors need to junction in one spot at the “load junction terminal strip”.
