The DSDC series offers a NEMA 3R or IP54 /IP55
protection standard. NOTICE: An option for Type 4X
or IP66/IP67 protection is available 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 accomodate 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.
WARNING
They can only be used in conjunction with mating
receptacles or plugs manufactured by MELTRIC or
DANGER
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
Factory jumpers are installed on devices
DANGER
intended for applications of 600VDC and
750VDC. The figure below shows the location of
CAUTION
these jumpers, DO NOT REMOVE them.
WARNING
NOTE: 750VDC DEVICES NOT UL LISTED.
AVISO

CAUTION
NOTICE
Dual Circuit DC Wiring Instruction for
Non-Load Break Applications
ADVERTENCIA
Some applications require connections with 2 separate
DANGER
DC circuits. This requires 4 contacts (or 5 if a ground
contact is used). In these cases:
CAUTION
• L3 and L2 are used for the (+) and (-) of the up to
AVISO
250 VDC circuit with the highest voltage.
• L1 and N are used for the (+) and (-) of the up to
250 VDC circuit with the lowest (or equal) voltage.
Connection
Verify the power source is de-energized.
DO NOT ENGAGE ON AN ENERGIZED CIRCUIT.
WARNING
To connect a plug and receptacle, first depress the
pawl to open the lid on the receptacle, then orient the
DANGER
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
CAUTION
the left of the latch on the receptacle casing. Push
the plug partially into the receptacle until it hits a stop,
NOTICE
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
ADVERTENCIA
straight into the receptacle as shown in figure 2 until
it becomes securely latched in place. The electrical
DANGER
connection is now made. On in-line connectors,
squeeze the drawplates on both sides of the device
CAUTION
together until the plug latches in place.
AVISO
As an added safety feature, the DSDC2 is provided
with a "locking pawl" to prevent any unintended
connections. To mate the devices, loosen the thumb
screw on the pawl, and follow steps 1 and 2. On the
DSDC9 and DSDC2 devices, an integral mechanism
provides easy connection of the plug to the receptacle.
With the DSDC9 or DSDC2 plug partially inserted and
rotated 30° so that it is positioned for connection, place
the wire clamps around the bolt heads 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. On the
DSDC2, tighten the thumb screw on the pawl to prevent
any unintended disconnection. A locking device
should be used when the devices are mated.

Disconnection
Before disconnection, verify the power source
is de-energized. DO NOT DISENGAGE ON
AN ENERGIZED CIRCUIT.
WARNING
To release the connection after the power source
has been turned off, simply depress the pawl as
DANGER
shown in figure 5 . This will eject the plug straight
out to the rest, or off, position. To remove the plug,
rotate it counter-clockwise (about 30°) until it releases
CAUTION
from the receptacle as shown in figure 6 . Close and
latch the lid on the receptacle. As an added safety
NOTICE
feature, DSDC2 is proved with a "locking pawl" to
prevent any unintended disconnections. To disconnect
ADVERTENCIA
the devices, loosen the thumb screw on the pawl, and
follow steps 5 and 6.
DANGER
CAUTION
AVISO
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.
WARNING
Rated ingress protection applies to the device when
the plug and receptacle are mated and latched together.
DANGER
It also applies to the receptacle when the lid is
latched closed.
CAUTION
Lockout Provisions
NOTICE
All DSDC devices are provided with lockout provisions,
which are designed for a 5/16" lock shank. These
ADVERTENCIA
may be used to "lock" the devices together to prevent
unintended disconnection, or to lock out the receptacle
DANGER
or inlet. To prevent an unintended disconnection, lock
the devices together by inserting a locking device
CAUTION
through the hole provided in the pawl after the plug
and receptacle have been connected.
To lockout the plug, insert a locking device through
the hole provided in the casing. This will prevent the
plug from being inserted into a receptacle.
To lockout the receptacle, close and latch the lid and
then insert the locking device through the hole provided in
the pawl. This will prevent the lid from being opened
for the insertion of a plug.
MAINTENANCE
WARNING
Before inspecting, repairing, or
maintaining MELTRIC products,
DANGER
disconnect electrical power to the receptacle to 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:
ADVERTENCIA
• Check the mounting screws for tightness.
DANGER
• Verify that the weight of the cable is supported
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 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.
