Periodic inspection and replacement of the gaskets may be
required to maintain water tightness in the pictured Type

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

OPERATION
To ensure safe and reliable operation MELTRIC
plugs and receptacles must be used in
accordance with their assigned ratings.
WARNING
MELTRIC plugs can only be used in conjunction
with mating receptacles or plugs manufactured by
DANGER
MELTRIC or another licensed producer of products
bearing the
technology trademark.
CAUTION
MELTRIC plugs & receptacles are designed with
different keying arrangements, so that only plugs and
NOTICE
receptacles with compatible contact configurations and
electrical 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, then orient the
CAUTION
plug as shown in figure 1 so that the red dot on the
outside of the casing lines up with the red dot just to
AVISO
the left of the latch on the receptacle casing. Using
a straight motion, 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 as shown in
figure 2 until it becomes securely latched in place.
On in-line connectors with drawplates, squeeze the
drawplates on both sides of the device together until
the plug latches in place.

On the DR150, DR250 & DR400 devices, an integral
mechanism provides easy connection of the plug to the
receptacle. With the DR150, DR250 & DR400 plug
partially inserted and rotated 30° so that it is positioned
for connection, place the wire clamps around the
boltheads as shown in figure 3
To pull the plug into the receptacle, simply push the
handles back along the side of the receptacle and then
push the plug into the receptacle until the plug
is latched in place, as shown in figure 4. The
electrical connection is now made. The mechanism
must be released to allow disconnection of the device.

Achieving Environmental Ratings and Watertightness
For devices rated Type 4, 4X or 3R, use only
with mating devices having identical markings to
maintain enclosure rating of the mated pair.
Rated ingress protection applies to the device when
WARNING
the plug and receptacle are mated and latched
together. It also applies to the receptacle when the lid
DANGER
is latched closed.
CAUTION
Lockout Provisions
NOTICE
Some MELTRIC plugs are provided with lockout
provisions. To lockout the plug, insert a locking device
ADVERTENCIA
through the hole provided in the casing. This will
prevent the plug from being inserted into a receptacle.
DANGER
Some receptacles may be purchased with optional
CAUTION
lockout provisions and used with 5/16-inch shank
locks. To lockout the receptacle, close and latch the
lid and then attach the locking device through the hole
AVISO
provided in the pawl. 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 of the receptacle 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
NOTICE
the 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.
Replace as required.
AVISO
• Verify the electrical continuity of the ground circuit.
• Check the 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
electrician. This should only be done with the power
off. It is accomplished by depressing the numbered
ring around the circumference of the interior on two
opposite points. This will allow the shutter to be
manually turned clockwise as required to permit access
to the contacts. Once the inspection is complete, the
shutter must be rotated counter-clockwise until it is
locked in the closed position.
