1.2.1 AC Input Connections
Before beginning any work inside the charger
enclosure ensure that all incoming AC supply and DC
load wires are de-energized. Verify that no voltage is
present inside the case by using a voltmeter at all
input and output terminals. Check that the source
voltage and frequency match the charger front
nameplate specifications. Select wire size, using
Table 3 to the right.
NOTE: These are recommended sizes. All National
and Local Wiring Codes must be followed
