The PDM provides customer receptacle options for singleĆ and threeĆphase
applications. The PDM also has a hardwire output panel for mixing hardware and
receptacle output configurations.
NOTE: The PDM cannot be installed on units with a 127/220V configuration.
Only qualified service personnel (such as a licensed electrician) should
perform the PDM installation. Risk of electrical shock.
To perform the PDM installation, you need the following tools: a 1/4 I hexĆnut driver, a
small flatĆhead screwdriver, and a 1 3/8 I wrench. Make sure that you read all of the
caution and warning statements in Safety Considerations" beginning on page before
performing the installation.
The following instructions assume you have already installed the UPS and battery
cabinets according to the procedure in Installing the UPS and Battery Cabinets" on
page 34.
The critical load is deĆenergized during the PDM cabinet installation.
Make sure your UPS is shut down before performing any steps in this section
(see page 23).
