is installed with the pawl / latch at the top.
NOTICE: If the device is mounted to a wall box, make
sure that appropriate hole plugs are securely tightened
in any unused connection holes.
Insert the cable or wires through the wall box and
cut
to allow adequate length, strip the cable sheath,
as desired, strip the individual wires to the lengths
indicated in Table 3, and twist the strands of each
conductor together. Back out the terminal screws on
the receptacle (or inlet) far enough (but not completely)
to allow the conductors to pass, insert the conductors
fully into their respective terminals and tighten the
terminal screws to the torque indicated in Table 4, with
a hand screwdriver.
Assemble the receptacle (or inlet) and the color-coded
gasket to the box with appropriate hardware.
NOTICE: Over-tightening the screws may cause cracking
in polymeric components. Assemble the mating plug
(or receptacle) to the cord end as indicated in the
assembly instructions above for in-line connections,
except there will be no finger drawplate or associated
black gasket.
In cases where custom mounting is being performed
to an appropriate hazardous duty box or panel, the
clearance and mounting holes should be drilled as
indicated in the following diagram.

NOTICE: In order to maintain IP66/IP67 protection
in custom installations, watertight seals must be used
under the heads of the four mounting bolts and they
must be retained by a lock washer and nut on the inside
of the box or panel. Alternatively, four blind holes can
be drilled and threaded to accommodate #8-32 x 5/8"
mounting screws. The hole depth must be sufficient to
achieve adequate gasket compression.
OPERATION
To ensure safe and reliable operation,
MELTRIC plugs and receptacles must be used
in accordance with their assigned ratings.
They can only be used in conjunction with mating
receptacles or plugs manufactured by MELTRIC or
WARNING
another licensed producer of products bearing the
technology trademark.
DANGER
MELTRIC plugs & receptacles are designed with
different keying arrangements, so that only plugs
and receptacles with compatible contact configura-
CAUTION
tions and electrical ratings will mate with each other.
Connection
NOTICE
To connect a plug and receptacle, first depress the
pawl to open the lid on the receptacle, then orient
the plug 1. so that the red arrow on the outside of
the casing lines up with the red arrow just to the left
of the latch on the receptacle casing. Push the plug
partially into the receptacle until it hits a stop, then
rotate the plug in the clockwise direction until it hits
another stop after about 30° of rotation. At this point,
the circuit is still open. Push the plug straight into
the receptacle 2. until it becomes securely latched in
place. The connection is now made. For in-line connectors,
squeeze the drawplates on both sides of the device
together until the plug latches in place.

NOTICE: When making a connection, ensure that
the plug latch is secured behind the catch on the blue
pawl. A properly connected plug cannot be pulled out
of the receptacle.
Disconnection
To break the connection, simply depress the pawl
as shown in figure 3. This will break the circuit and
eject the plug straight out to the rest, or off, position.
The plug contacts are de-energized at this point. To
remove the plug, rotate it counterclockwise (CCW)
(about 30°) until it releases from the receptacle as
shown in figure 4. Close and latch the lid on the
receptacle.

Achieving Watertightness Ratings
DXN's have an IP66/IP67 rating for protection against
ingress of water, dust and other matter. IP66 provides
total protection against dust and water jets. IP67 adds
protection for temporary immersion in shallow water.
These ratings apply when the plug and receptacle
are mated. They also apply to the receptacle alone,
provided that its lid is latched in the closed position.
Optional plug caps are available for providing IP66/
IP67 protection on unmated plugs.
NOTICE: MELTRIC threaded handles come with
tapered style threads.The use of fitting seal tape is
recommended to maintain watertightness of all NPT
fittings and joints.
Lockout Provisions
All DXN plugs are provided with lockout provisions. To
lockout the plug, insert the locking device through the
hole provided in the casing. This will prevent the plug
from being able to be inserted into a receptacle.
Receptacles can be purchased with optional lockout
provisions. MELTRIC's Locking Pin must be used to
lockout the receptacle. Close and latch the lid. Slide
MELTRIC's Locking Pin through the hole provided in
the latch and place a padlock or other locking device
through one of the holes on the locking pin. This will
prevent the lid from being opened.
NOTICE: Attaching the receptacle locking device with
the lid open will not prevent the insertion of a plug.
