Plug-Receptacle PDM Installation
The following steps explain how to install the PDM.
NOTE Do not make unauthorized changes to the UPS; otherwise,
damage may occur to your equipment and void your warranty.
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. Verify that the PDM output circuit breaker is in the OFF position
(see Figure 8).
3. Verify that the Bypass switch on the PDM is in the NORMAL
position (see Figure 7).

4. Changing the PDM output voltage. When the PDM voltage
switch is set to the 240V position (the default), the output
voltage is 240V/120V. When set to the 208V position, the output
voltage is 208V/120V. See Table 1 for a complete list of PDM
input/output voltage settings. Figure 7 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.
