3.3 Rear Panel Controls
1. DUT POWER INPUT CONNECTOR
This connector provides the Line and Neutral input power connections on pin 1 and 2
respectively. An external single phase unbalanced AC power supply with a single Hot or Line
conductor should be connected here, to supply power to the DUT while performing the
leakage test. This input is rated for 0-277 volts 50/60 Hz.
2. L TERMINAL
This output terminal is where the LINE power connection from the adapter box is plugged into
the run test or Touch Current test. Line power is supplied to the DUT during the run test or
Touch Current test through this terminal and High Voltage is supplied to the DUT through this
terminal during the Dielectric Withstand or Insulation Resistance. This terminal and the “N”
Terminal are shorted together when Dielectric Withstand or Insulation Resistance are being
performed.
3. N TERMINAL
This output terminal is where the NEUTRAL power connection from the adapter box is
plugged into the run test or Touch Current test. Line power is supplied to the DUT during the
run test or Touch Current test through this terminal and High Voltage is supplied to the DUT
through this terminal during the Dielectric Withstand or Insulation Resistance. This terminal
and the “L” Terminal are shorted together when Dielectric Withstand or Insulation Resistance
are being performed.
