1.0 INTRODUCTION
Gravitas X75 is an ultra-compact, integrated DC power system. The base system is a 1RU
shelf holding up to three hot-swap rectier modules. This system produces up to 1950 watts
output at -54.4, +27.2 or +13.6VDC. It can also be operated as a 2+1 redundant system with
up to 1300 watts output. The expanded system consists of a base shelf plus an expander
shelf with a 2RU total height. This system holds up to six rectier modules with up to 3900
watts output; it can be operated as a 5+1 redundant system with up to 3250 watts output.
Each rectier module is cooled by a fan that operates at a speed which is a function of load
and temperature.
There are up to ve circuit-breaker protected DC outputs or up to 10 GMT fuse protected
outputs on the base system. A battery string breaker and a low-voltage battery disconnect
are standard features. The expander shelf comes with a ribbon cable and connectors to link
the signals between the two units at their rear panels. It also comes with bus bar links to
parallel the rectier output bus bars.
The base and expander shelves can also be operated as a battery backup, single feed power
system (without load circuit breakers or fuses).
The remote access controller has LED visual indicators and Form C relay alarms. It is
programmed by means of a remote PC web page display with communication by Ethernet
LAN. Temperature compensated rectier output is provided by means of an accessory TC
probe. The X75 can be quickly installed by a qualied technician.

3.0 SAFETY WARNINGS
3.1 The X75 Compact DC Power System operates at voltages that could potentially be
hazardous. Furthermore, inadvertent short circuiting of the system battery and/or
rectier by mis-connection or other error could be harmful. This product should be
handled, tested and installed only by qualied technical persons who are trained in
the use of power systems and are well aware of the hazards involved.
3.2 All connections to the X75 should be carefully checked for errors before applying
power to it.
3.3 SpecicConsiderationsforRackMountedEquipment
3.3.1 Elevated OperatingAmbient - If installed in a closed or multi-unit rack
assembly, the operating ambient temperature of the rack environment may be greater
than room ambient. Therefore, consideration should be given to installing the X75
in an environment compatible with the maximum ambient temperature of 50°C at
full rated load, and at 70°C at derated load at a derating factor of 2.5%/°C from
50°C to 70°C.
3.3.2ReducedAirFlow- Installation of the X75 in a rack should be such that the
amount of air ow required for safe operation of the equipment is not compromised.
3.3.3MechanicalLoading- Mounting of the X75 in the rack should be such that a
hazardous condition is not achieved due to uneven mechanical loading.
3.3.4CircuitOverloading- Consideration should be given to the connection of the
X75 to the supply circuit and the effect that overloading of the circuits might have
on over-current protection and supply wiring. Appropriate consideration of the X75
nameplate ratings should be used when addressing this concern.
3.3.5ReliableEarthing- Reliable earthing of rack-mounted equipment should be
maintained. Particular attention should be given to supply connections other than
direct connections to the branch circuit (e.g. use of power strips).”
3.4 TheX75isintendedonlyforinstallationina“RESTRICTEDACCESSLOCATION”.
3.5 Input/output short circuit ratings are 5KAAC for terminals connected to breakers
and 450AAC for terminals connected to GMT type fuses.

5.0 UNPACKING AND INSPECTION
5.1 This X75DCpower system was carefullytested,inspectedandpackagedfor shipment
from our factory. Upon receipt the unit should be carefully unpacked and inspected
for any damage in shipment.
5.2 If there is evidence of damage, donotattempttoinstalltheunit. The freight carrier
should be notied immediately and a claim for the cost of the X75 should be led
with the carrier for direct reimbursement. Be sure to include the model and serial
number of the damaged unit in all correspondence with the freight carrier. Also

7.1 85-264VAC is supplied directly to each of the rectiers which produce a nominal
-48VDC, +24VDC or +12VDC output.
7.2 Following a current shunt to measure the rectier current, the rectier DC output
is fed to the battery terminals via the LVD (Low Voltage Disconnect, current shunt
and a 100A circuit breaker.
7.3 The rectifier DC output is also fed to the loads via up to 5 circuit breakers
(conguration A) or 10 fused circuits (conguration B).
