Verify that the cable jacket extends beyond the strain relief
and into the handle. Assemble the receptacle (or inlet), the
color coded gasket, the finger drawplate, and the thin black
drawplate gasket to the handle with the four self-tapping
screws provided. Adjust the cable location so that it will not
be under tension inside the handle and tighten the compres-
sion nut to secure the cable.
Assembly for Mounted Receptacles (or Inlets)
In applications where DS or DSN receptacles (or inlets)
are mounted to wall boxes, panels or other equipment,
optimal operation is achieved when the device is installed
with the latch at the top and with the force from the cable
being exerted in a downward direction opposite the latch.
Mount with the latching pawl at
the top to counteract the weight
and strain of the plug & cable.
Mount the receptacle
at a downward angle
whenever possible.
the receptacle (or inlet) far enough (but not completely) to
allow the conductors to pass, insert the conductors fully
into their respective terminals and hand tighten the terminal
screws to the torque indicated in Table 5.
Assemble the receptacle (or inlet) and the color-coded gas-
ket 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.

NOTICE: In order to maintain the Type 4X or IP 66 & 67
protection provided 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 specified ratings.

ADVERTENCIA
To connect a plug and receptacle, first depress the pawl
terminal screws on
to open the lid on the receptacle, then orient the 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 the left of the
CAUTION
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 DS100, DSN150 & DS200 devices, an
integral mechanism provides easy connection of the
plug to the receptacle. With the DS100, DSN150, or
DS200 plug partially inserted and rotated 30° so that
it is positioned for connection, place the wire clamps
around the latches 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 electri-
cal connection is now made. The mechanism must be
released to allow disconnection of the device.
Disconnection

To break the connection, simply depress the pawl
as shown in figure 5 . 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 counter-clockwise (about
30°) until it releases from the receptacle as shown in
'C'
figure 6 . Close and latch the lid on the receptacle.

Achieving Environmental Ratings & 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 is latched.
DANGER
Lockout Provisions
CAUTION
All DS and DSN plugs are provided with lockout
provisions. To lockout the plug, insert a locking device
NOTICE
through the hole provided in the casing. This will pre-
vent the plug from being inserted into a receptacle.
ADVERTENCIA
DS and DSN receptacles may be purchased with
optional lockout provisions and used with 5/16-inch
DANGER
shank locks. To lockout the receptacle, close and
latch the lid and then attach the locking device
CAUTION
through the hole provided in the pawl. This will prevent
the lid from being opened for the insertion of a plug.
AVISO
NOTICE: Attaching the receptacle locking device
with the receptacle lid open will not prevent the in-
sertion of a plug. Lockout of the receptacle is only
accomplished when the lid is locked closed.
MAINTENANCE
Before inspecting, repairing,
WARNING
or maintaining MELTRIC
products, disconnect electrical power to the receptacle
DANGER
to eliminate the risk of electrical shock.
CAUTION
MELTRIC products require little on-going mainte-
nance. However, it is a good practice to periodically
NOTICE
perform 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 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.
