installation and safe use of the product.
WARNING
DANGER
precautions can result in serious injury or death. These instructions
must be followed to ensure the safe and proper installation, operation

RATINGS
ADVERTENCIA
The DN9c and DN20c products are manufactured and load-break
DANGER
rated in compliance with CSA Standard C22.2 No. 182.1. The product
ratings are indicated on the device's labels. Additionally the DN9c and
CAUTION
DN20c are HP rated for multiple HP loads as long as any single HP
load doesn't exceed the levels shown in Table 1. Their short circuit
AVISO
withstand levels and fuse ratings are shown in Table 2.

INSTALLATION
These products should be installed by qualified personnel
in accordance with all applicable local, state and national
electrical codes. Before starting, verify that the power is turned off; the
product ratings are appropriate for the application; and the conductor

General Notes & Precautions
1. Self-tapping screws are provided for use with some polymeric
CAUTION
accessories. NOTICE: Once they are seated, care should be
taken in order to avoid over-tightening them against the plastic
AVISO
material.
2 Various handles, cord grips or strain relief options may be used.
These instructions are based on handles provided with integral,
multi-layer, bushing cord grips.
3. Wire strip lengths are indicated in Table 4. Strip lengths for cable
sheathing will depend on the specific application.

4. Wiring terminals are spring-assisted to prevent loosening due to wire
strand settlement, vibration and thermal cycling. NOTICE: They
should not be over-tightened. Appropriate tools and tightening
torques are indicated in Table 5.

The DN9c and DN20c plugs and receptacles' contacts are labeled with
F or S numbers respectively. The F-number on the inlet has a
corresponding S-number on the receptacle. See table 6 for details.

Assembly for In-line Connections
Do not overtighten terminal or self-tapping screws. Tighten screws
to the proper torque to ensure a secure connection.
When the DN9c product is used as an in-line connector, finger
drawplates should be installed on both the receptacle and plug in order
WARNING
to provide the user with the leverage to connect the device.
DANGER
NOTICE: The longer screws provided with the finger drawplates must
be used when assembling devices with finger drawplates because the
CAUTION
shorter screws provided with the handle are not long enough to
properly secure both the handle and drawplates to the inlet or
receptacle and achieve a watertight connection.

Relief
Compression
Nut
Adjust the bushing diameter to fit the cable by removing the inner
sections as required. Insert the bushing into the strain relief, then
insert the assembly into the handle and loosely install the compression
nut. Insert the cable through the handle, the thin black (neoprene)
drawplate gasket, the finger drawplate (if applicable) and the color
coded gasket. Strip the cable sheath to provide a workable wire
length, being mindful that the sheath must extend into the handle to
achieve a secure cord grip. Then strip the individual wires to the lengths
indicated in Table 2 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 with the appropriate tool to the torque indicated in Table 3.
Verify that the cable sheath extends beyond the strain relief and into
the handle. Assemble the receptacle (or inlet), the color coded gasket,
followed by the finger drawplate, and the thin black (neoprene) drawplate
gasket (if applicable) to the handle and tighten the compression nut to
secure the cable.
Assembly for Mounted Receptacles (or Inlets)
In applications where the receptacles (or inlets) are mounted to wall
boxes, panels or other equipment, optimal operation is achieved when
the devices are installed with the latch at the top.
Insert the cable or wires through the wall box and cut to allow
adequate length. Strip the cable sheath as desired, then strip the
individual wires to the lengths indicated in Table 2 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 hand tighten the terminal screws to the torque indicated
in Table 3.
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 receptacles or plugs
WARNING
manufactured by MELTRIC ® or another licensed producer of products
bearing the
DANGER
MELTRIC ® plugs & receptacles are designed with different keying
CAUTION
arrangements so that only plugs and receptacles with compatible
contact configurations and electrical ratings will mate with each other.
NOTICE
Connection
ADVERTENCIA
To connect a plug and receptacle, first depress the pawl to open the
lid on the receptacle and orient the plug as shown in figure 1. Push
DANGER
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
CAUTION
circuit is 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 recom- AVISO
mended. 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
DANGER
power to the receptacle to eliminate the risk of electrical shock.
MELTRIC ® products require little on-going maintenance. However,
CAUTION
it is a good practice to periodically perform the following general
inspections:
NOTICE
• Check the mounting screws for tightness.
ADVERTENCIA
• Verify that the weight of the cable is supported by the strain relief
DANGER
mechanism and not by the terminal connections.
• Check the IP gaskets for wear and resiliency. Replace as required.
CAUTION
• Verify the electrical continuity of the ground circuit.
AVISO
• 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.
