Important SafetyInstructions
This manual contains important instructions that should be followed during installation and for
maintenance of the MPDU™system.
CAUTION
Install the MPDU™system in a temperature-controlled indoor environment where it is clean, dry, and
free of conductive contaminants.
CAUTION
For safety, please ensure that all individual circuit breakers are in the OFF position prior to installing the
MPDU™system to the Q-LS™system. Serious injury or death may result from failure to ensure that
all power connections are OFF.

1. INTRODUCTION
1.1 Description
The Main Power Distribution Unit™(MPDU) is designed with three-phase 120/208 VAC input. The unit supplies
single-phase 120 VAC and three-phase 120/208 VAC output power. The MPDU comes in four varieties with
different power output options: The Weapons Tactical Trainer (WTT), the Training System Support Center (TSSC),
Parts Task Trainer (PTT), and the Virtual Maintenance Trainer (VMT). The MPDU serves as the main source of AC
power into the training device(s). The MPDU monitors the status and distributes power to all equipment requiring AC
power within the training devices.
The MPDU features a user-friendly touchscreen to access data, which is monitored by sophisticated software. The
intelligent monitoring software is easily accessible through the user-friendly touchscreen on the front side of the unit as
well as remotely through a TCP/IP Ethernet connection. Using the software, the user can access real time data and
event history of the unit, as well as data and historical event data from both the MPDU and the attached Q-LS™system.
