Inspection and installation
WARNING
There are dangerously high voltages present within
the enclosure of the power supply system. Under no
circumstances should any person reach within the
enclosure of this equipment. All service to this piece
of equipment should be performed by qualified
personnel only.
Unpacking
Upon receipt of the unit, visually inspect for shipping
damage. If any damage is found, the Purchaser must
contact the Carrier immediately and file a shipping
damage claim.

Be sure to remove top and side panels and inspect
inside unit for shipping damage.
Eaton should be notified if the nature of damage is such
that operation of the equipment has been impaired. Please
call 1-800-809-2772, option 4, and then option 2.
Storing
If it is necessary to store the unit for a period of time
before it is installed, be sure to place the unit in a clean,
dry area. To prevent excessive dust from accumulating on
the unit, it is advisable to protect it by replacing it in the
original container. The unit must be handled at all times with
the same care you would give to any piece of precision
industrial equipment.
Choice of location
The unit has been completely inspected and extensively
tested under various load conditions prior to shipment.
Care to install it at a proper location will ensure long
trouble-free operation.
The unit is air cooled with the air intake at the bottom
and exhausts at the top, front or at the sides. Therefore,
it should be installed in a clean, dry place with enough
clearance to allow a free flow of air. Allow at least
4.00 inches (101.6 mm) of space between the unit and
the wall or other equipment. Allow enough space for
maintenance on all four sides of larger units.
Inspection
A. Remove top and side panels (not applicable on 225 kVA
and larger).
B. Check all electrical connections to be sure none have
loosened during shipment. Tighten if necessary. Check
for any internal damage.
C. Check the spec. plate on the front of the unit to be
sure that the voltage and frequency match the available
power supply. Under no circumstances should the
unit be connected to a power source which does not
conform to the spec. plate rating.
Installation procedure
A. Verify that the input voltage to the unit matches the
unit’s specification plate.
B. Refer to installation diagrams on
page 27
–
page 35
for input and output connection recommendations and
conduit locations.
Input wire size, grounding, and output wiring
A. Conduit should be used for both input and
output wiring.
B. Minimum ground wire size is based on 2011 National
Electrical Code
®
Table 250.122.
C. Input wire size is based on 2011 NEC
®
Table 310.15(B)(16)
specifying not more than three conductors in a raceway
based on ambient of 30 degrees Celsius, and wire rated
at 75 degrees Celsius.
D. Output neutral to ground is already bonded during
manufacturing of the Power-Sure 700.
E. Output requires four (five including ground wire)
conductors in a raceway assuming neutral as a
current carrying conductor. This requires conductors
to be derated by using a multiplier of .8, reference
2011 NEC Article 310.15(B)(3)(a).
Example
1. Assume #10 wire maximum current = 25 A.
2. Multiply 25 x .8 = 20.
3. 20 A is maximum current for #10 wire in a raceway
with four conductors.

Installation is subject to local codes—verify with a
local electrical inspector.
