Receiving and handling
Every effort is made to ensure that the Enclosed PXM equipment
arrives at its destination undamaged and ready for installation .
Crating and packing are designed to protect internal components
as well as the enclosure . Do not remove protective packing until
the equipment is ready for installation .
When the equipment reaches its destination, the customer should
inspect the shipping container for any obvious signs of rough
handling and/or external damage that occurred during transportation .
Record any external and internal damage for reporting to the
transportation carrier and Eaton, once a thorough inspection is
complete . All claims should be as specific as possible and include
general order numbers .
A plastic bag of instruction booklets and/or CDs will be found in the
shipping container . Store these documents in a safe place .
Storage
Although well packaged, this equipment is not suitable for storage
outdoors . And if the equipment is to be stored indoors for any period
of time, it should be stored with its protective packaging in place .

installation and wiring
General
Enclosed PXM devices are factory wired and tested . Installation
requires solidly mounting the enclosed unit and connecting field
wiring . Included in this booklet are diagrams of the factory wiring
and various field wiring options . Review and understand the
appropriate diagrams for the catalog number of the unit you
have ordered .
The system voltage application is assumed to be a three-phase,
four-wire system for both the models with and without a CPT . For
a model with a CPT, the primary voltage is assumed to be 480 Vac
with a secondary voltage of 120 Vac . It is also assumed that there
will be five CTs used in the application for monitoring the current of
the system . For applications that are three-phase, three-wire, and
different CT configurations, please see Chapter 3 of the
User and
Installation Manual
IM02601004E for further details and configuration
options . All models containing an I/O card and RJ45 communications
connections will be required to have the external wires connected
directly to the PXM device .
Mounting location
Choose a location that offers a flat, rigid mounting surface capable of
supporting the weight of the equipment (
Figure 1
through
Figure 3
) .
Units will weigh 85 lbs (38 .6 kg) maximum . Mount the equipment
in a suitable environment . These enclosures are designed for
NEMA 12, 3R, and 4X environments . The catalog number identifies
the enclosure . If there are any doubts as to location suitability,
discuss them with your Eaton representative . Check to make
certain that there are no pipes, wires, or other mounting hazards
in the immediate mounting area that could create a problem .
Carefully remove all packing material from the unit . Even though
an equipment inspection was made when the equipment was
received, make another careful inspection of the enclosure and the
devices inside as packing material is removed . Be especially alert for
distorted metal, loose wires, or damaged components .
Mounting procedure
The enclosures are provided with four elongated mounting holes,
two at the top mounting flange and two at the bottom .
Knockout procedure
Use an appropriate knockout punching tool for incoming power
connections . In addition, the use of an appropriate NEMA-rated
hub is required to maintain enclosure NEMA rating .
