INSTALLATION INSTRUCTIONS
Open Line/Load Reactor Installation
MTE line/load reactors are available in open
construction and in NEMA 1 enclosures.
Open reactors are designed for mounting within
an appropriate electrical equipment
enclosure. Reactors rated 300 amperes RMS
and under are designed for mounting in both a
vertical and horizontal position. Larger
reactors must be mounted in a horizontal
position typically on the floor of the enclosure.
Include the power dissipation of the reactor
along with all the other components located in
the enclosure to determine the internal
temperature rise and cooling requirements
of the enclosure.
Reactors may be located in any region of the
enclosure where the ambient temperature
does not exceed 45 degrees C. Allow a minimum
side clearances of four (4) inches and vertical
clearances of six (6) inches for proper heat
dissipation and access. Do not locate the
reactor next to resistors or any other component
with operating surface temperatures above
125-degree C.
Select a well ventilated, dust-free area away from
direct sunlight, rain or moisture. Do not install in or
near a corrosive environment. Avoid locations
where the reactor will be subjected to
excessive vibrations.
NEMA 1 Line/Load Reactor Installation
Top conduit entry recommended for
NEMA 1 enclosed reactors.
MTE line/load reactors mounted in enclosures
with part number, CAB-8, are designed for
wall mounting. All other enclosures are
designed for floor mounting.
WARNING
MTE NEMA 1 enclosures designed for floor
mounting must be mounted with the
enclosure base horizontal for proper
ventilation. Wall mounting a floor
mounted enclosure with the base against
the wall will cause the reactor to over heat
resulting in equipment damage.
Allow a minimum side, front, and back
clearances of twelve (12) inches and vertical
clearances of eighteen (18) inches for proper
heat dissipation and access. Do not locate the
enclosure next to resistors or any other
component with operating surface temperatures
above 125-degree C.
Select a well ventilated, dust-free area away
from direct sunlight, rain or moisture
where the ambient temperature does not
exceed 40 degrees C.
Do not install in or near a corrosive environment.
Avoid locations where the reactor will be
subjected to excessive vibrations.
Where desirable, enclosures may be mounted
on vibration isolating pads to reduce audible
noise. Standard vibration control pads made
from neoprene or natural rubber and
selected for the weight of the enclosed reactor
are effective. Using flexible conduit is also
helpful in abatement of audible noise.
