  • Page 33: Output Connections To The Load

    2.9.1 SW 5550AE Output Connections The Model SW 5550AE can power 1-phase, 2-phase and 3-phase loads. Local or remote sensing can be used; if no sense lines are connected, the unit automatically reverts to local sense. Outputs may be directly paralleled for greater power. If the outputs are paralleled it is important to program the unit to the parallel mode before shorting the outputs together (refer to Figure 2–4).

    SW 5550AE • SW 3700AE • SW 1850AE Installation 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.

  • Page 36: Table 2-9 Recommended Wire Gauge Selection Guide

    Installation SW 5550AE • SW 3700AE • SW 1850AE Such a loss directly detracts from the quality performance specifications of this Elgar instrument. Frequently, these codes do not consider bundles of wire within a cable arrangement. In high performance applications, as in motor start-up and associated inrush/ transient currents, additional consideration is required.
  • Page 37 SW 5550AE • SW 3700AE • SW 1850AE Installation The following notes apply to Table 2–9 and to the power cable definition: The above figures are based upon insulated copper conductors at 25°C (77°F), two current carrying conductors in the cable plus a safety (chassis) ground.
  • Page 38 Installation SW 5550AE • SW 3700AE • SW 1850AE Aluminum wire is not recommended due to soft metal migration at the terminals, which may cause long term (on the order of years) poor connections and oxidation. If used, increase the wire gauge by two sizes (e.g., specify 10 gauge aluminum instead of 14 gauge aluminum).
