4 . 2 . 1 Transformer Wiring
One of two types of transformers is installed in the starter assembly.
Check the wiring configuration of the transformer before applying ac
power to the HPS.

Optional transformer
wiring An optional multi-tap transformer may be used for source voltages other
than 230 Vac and 460 Vac. The following figure shows the typical
wiring required for various voltages. Source voltages are applied to
terminals H1 through H5 as shown. An output voltage is tapped from
terminals X1 through X4. Check the output voltage with a voltmeter.
It should be 110 Vac for systems using 50 Hz power and 115 to 120 Vac for
systems with 60 Hz.
