4.1.1 Connections
The required supply voltage for the inverter is 380v/50Hz to 480v/60Hz. For other available three-phase
voltages including 460v, an autotransformer is provided to supply the proper voltage to the inverter. See
Section 1.4, Operating Tests, with regards to the verification of the output voltage from the autotransformer
to the inverter.
Power and control circuit connections are made to X1 terminal as follows:

A minimum of two collectors for each runway conductor shall be used with inverter use.
In addition, the use of a ground shall be utilized, either through the frame ground or a conductor ground.
Proper grounding is important with inverter use. A poor ground could cause damage to the inverter or could
create a shock hazard to personnel.
