Assemble the receptacle (or inlet) and the color coded
gasket to the box with the appropriate hardware. 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.
Hole Pattern for Custom Mounting
In applications where custom mounting to a panel or box
is desired, the clearance and mounting holes should be
drilled as indicated in the following diagram and Table 7.

NOTICE: In order to maintain the IP protection provided
by DN models in custom installations, watertight seals
should 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 may be drilled and threaded to accommodate the
mounting screws, provided that the hole depth is 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
WARNING
receptacles or plugs manufactured by MELTRIC or
another licensed producer of products bearing the
DANGER
™ technology trademark.
CAUTION
MELTRIC plugs & receptacles are designed with different
keying arrangements so that only plugs and receptacles
with compatible contact configurations and electrical
NOTICE
ratings will mate with each other.
ADVERTENCIA
Connection
DANGER
To connect a plug and receptacle, first depress the pawl
to open the lid on the receptacle and orient the plug as
CAUTION
shown in figure 1. Push the plug partially into the receptacle
until it hits a stop and then rotate the plug in the counter-
clockwise direction about 30°. At this point, the circuit is
AVISO
still open. Push the plug straight into the receptacle 2.
until it becomes securely latched in place. The electrical
connection is now made. For in-line connections, the use
of finger drawplates is recommended. When finger drawplates
are used, squeeze the drawplates on both sides of the
device together until the plug latches in place.

Disconnection
To disconnect, simply depress the pawl 3. This will open
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 clockwise about 30˚ until it
releases from the receptacle 4. Close and latch the lid
on the receptacle.
Achieving Rated Watertightness
Rated ingress protection applies to the device when the
plug and receptacle are mated and latched together.
It also applies to the receptacle when the lid is latched
closed.
Lockout Provisions
Some MELTRIC receptacles may be purchased with
optional lockout provisions. To lockout the receptacle,
close and latch the lid and then attach the locking device
through the hole provided in the pawl or shroud. This will
prevent the lid from being opened for the insertion of a
plug.
NOTICE: Attaching the receptacle locking device with
the receptacle lid open will not prevent the insertion of a
plug. Lockout is only accomplished when the lid is locked
closed.
MAINTENANCE
WARNING
Before inspecting, repairing,
or maintaining MELTRIC
products, disconnect electrical power to the receptacle to
DANGER
eliminate the risk of electrical shock.
CAUTION
MELTRIC products require little on-going maintenance.
However, it is a good practice to periodically perform the
NOTICE
following general inspections:
• Check the mounting screws for tightness.
ADVERTENCIA
• Verify that the weight of the cable is supported
DANGER
by the strain relief mechanism and not by the
terminal connections.
CAUTION
• Check the IP gaskets for wear and resiliency.
AVISO
Replace as required.
• Verify the electrical continuity of the ground circuit.
• Check the pin contact surfaces for cleanliness and
pitting.
Deposits of dust or similar foreign materials can be
rubbed off the contacts with a clean cloth. Sprays should
not be used, as they tend to collect dirt. If any significant
pitting of the contacts or other serious damage is observed,
the device should be replaced.
Receptacle contacts may be inspected by a qualified
technician. This should only be done with the power
turned off. The inlet contacts can be inspected by pressing
on opposite ends of the numbered face. This will make it
easier to check the contacts for pitting or damage.
