FC 6571 PDM Models: Changing the PDM voltage switch setting. When
the PDM voltage switch is set to the 208V position (the default)
with 208V input, the output voltage is 208V/120V. When set to the
240V position with 240V input, the output voltage is 240V/120V.
See Table 11 for a complete list of PDM input/output voltage
settings. Figure 17 shows the voltage switch.
NOTE In most applications, the voltage switch does NOT need changing.
To change the switch position, remove the bracket screw and turn
the switch. Flip the bracket around to fit the new position and
reinstall.

Neutral-to-Ground Bonding. The PDM has a neutral-to-ground (N-G or
neutral-to-earth) bonding screw as required under safety regulations
issued by various regulatory agencies. If the neutral-to-ground
connection is not needed, remove the screw to remove the bond
between neutral and ground.

Plug the input and output cords of the PDM into the input and
output power connectors on the UPS rear panel (see Figure 18).
