1.1.7 Fault Monitoring
The following conditions can initiate a PDU shutdown and trip the PDU main input
breaker CB1. These features can be enabled, disabled, or configured by an Eaton
Customer Service Engineer.
S
Overload Shutdown – An overload beyond a pre−set level is detected. This level can
be set at 100%, 110%, or 125% of maximum rated output, or at a
customer−specified level.
S
Over or Under Voltage Shutdown – An over or under voltage beyond pre−set levels is
detected. This level can be set at ± 5% of the nominal voltage detected for a period
greater than 5 seconds.
S
Over or Under Frequency Shutdown – An over or under frequency beyond pre−set
levels is detected. This level can be set at ± 15% of the nominal frequency
detected for a period greater than 5 seconds.
S
Phase Rotation Shutdown – A phase wiring error is detected.
S
Phase Loss Shutdown – A phase loss is detected on both the input and the output.
S
Ground and Neutral Overcurrent Shutdown – A ground or neutral overcurrent is
detected beyond a pre−set value.
1.1.8 Installation Features
Cabinets can be permanently bolted to the floor or left standing on leveling feet.
Power and control wiring can be routed through the top or bottom of the cabinet with
connections made to easily accessible terminals.
Optional X−Slot connectivity cards are quickly installed at the front of the unit and are
hot−pluggable.
1.1.9 Expansion
The PDU supports custom configurations and scalability to adapt to changing and
future power and distribution needs. See paragraph 1.2 for available options.
1.2 Options
The following options are available to enhance the performance of your system.
Contact an Eaton sales representative for information about any of these available
options.
1.2.1 Distribution Panels
Optional output 225A distribution panels distribute the output power from the AC
source to the load. The PDU contains up to two 42−circuit breaker panels
(Cutler-Hammer bolt-on type BAB or QBHW, or plug-on type HQP or QPHW) that can
be configured to meet facility needs. The distribution panels are behind the hinged
doors on the front of the PDU.
1.2.2 Subfeed Breakers
Optional output subfeed breakers distribute the output power from the AC source to
larger loads or remote power panels. The subfeed breakers are enclosed behind the
hinged doors on the front of the PDU. The PDU can contain up to eight 225A F"
frame subfeed breakers.
