To hardwire the PDM:
1.
If you are installing power management software, connect your
computer to the USB port or UPS communication port. For the
communication port, use only the serial cable supplied in the
accessory kit.
2.
Switch off utility power at the distribution point where the PDM will
be connected. Be absolutely sure there is no power.
3.
Verify that the PDM output circuit breaker is in the OFF position
(see Figure 10 on page 23).
4.
Verify that the bypass switch on the PDM is in the NORMAL
position (see Figure 9).

5.
Changing the PDM voltage switch setting.
When the PDM voltage
switch is set to the 240V position (the default) with 240V input, the
output voltage is 240/120V. When set to the 208V position with
208V input, the output voltage is 208/120V. See Table 1 for a list of
PDM input/output voltage settings. Figure 9 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.
