    2. Installation 2.1 About this chapter This chapter provides information on unpacking and installing the iL Series AC power source. If you are setting up this instrument for the first time, please study this chapter carefully before proceeding. If the AC source has already been setup, this chapter can be used for periodic inspection of the setup.

  • Page 19: Bench Operation

    Do not block the fan exhaust at the rear of the unit. Figure 4 Outline Diagram 2.6 Rack Mounting Due to their size and weight, iL Series AC power sources are frequently rack mounted. The three iL models weigh 87.7 kg (193 lbs). Note: Obtain adequate help when moving or mounting the unit in the rack.

  • Page 20: Input Connections

    In order to maintain phase current balancing, the power service should be a dedicated line with only iL Series AC sources drawing current from it. A disconnect box located near the AC source is recommended for all installations and is mandatory for direct-wired installations.

    Series User Manual Figure 5 Connecting the Power Cord 2.7.2 Output Connections The power output terminal block has a termination for each of the output phases and a floating neutral line for the phase return connections. A separate earth ground terminal is located near the output terminals.

  • Page 22: Table 6 : American Wire Gage (Awg) Characteristics

    Series User Manual 2.7.3 Wire Considerations Current Ratings Fire Hazard: To satisfy safety requirements, load wires must be large enough not to overheat when carrying the maximum short- circuit current of the AC source. If there is more than one load, then any pair of load wires must be capable of safely carrying the full-rated current of the AC source.

  • Page 23: Figure 7 Remote Sense Connections

    Series User Manual 2.7.4 Remote Sense Connections During operation, the AC source senses the output voltage at the output terminals on the back of the unit. External sense terminals on the back of the unit allow the output voltages to be sensed at the load, which compensates for impedance losses in the load wiring.

  • Page 24: Ovp Considerations

    Series User Manual 2.8 OVP Considerations The overvoltage protection circuit senses voltage near the output terminals, not at the load. Therefore the signal sensed by the OVP circuit can be significantly higher than the actual voltage at the load. When using remote sensing, you must program the OVP trip voltage high enough to compensate for the voltage drop between the output terminals and the load.
