Crimped/Soldered Terminal Wire Connections:
For 18 AWG and 16 AWG wire, the use of ferrules is required:
1. Strip each conductor to 25/64-inches (10-mm).
2. Insert ferrule into contact. For 16 AWG wire, use ferrules marked
MEC7177071. For 18 AWG wire insert ferrule 22170-13 into ferrule
MEC7177071.
3. Insert stripped wire end into ferrule.(Perform either step 4 or 5)
4. For Crimping the Contacts, use either North American Contact
Crimping Tool 4CN30 (using crimping slot 12-10) or Crimp contact
with European Contact Crimping Tool 61-CA500 (using 4 MM slot).
*With 4CN30 - Double crimp, once near the terminal opening and a
second crimp slightly above the first, rotated 180 degrees.
*With 61-CA500 - Double crimp, once near the terminal opening and
a second time slightly above the first location, rotated 90 degrees.
5. NOTICE: Soldering of the wire into the contact must be performed
with the contact out of the Interior Insulator to prevent damage to the
insulator.
• Using tin solder and a 50W soldering iron, heat the terminal for
approximately 30 seconds. While heating, apply the soldering wire
into the hole at the bottom of the terminal and let it penetrate by
capillary action. Let it cool down without any mechanical stress.
6. Slide the Heat Shrink Insulation Sleeve over the contact until it butts
up against the contact shoulder. NOTICE: Sleeve must be applied to
maintain creepage and clearance distance. Please see picture.
7. With a Heat Gun that has a temperature range of 600°F to 950°F,
apply heat evenly 360° around the sleeve until it shrinks around the
contact and wire.
Assembly of Contacts
Once wired, the contacts must be inserted into the rear of their respective
insulating block. The rear side of the inlet/plug or receptacle/connector is
considered as the flat surface of the 4-bolt hole mounting surface.
1. NOTICE: Before insertion of a contact into an insulator, please review
the insulator's contact numbering scheme so the ground and each
contact (phase) is placed into the proper hole.
2. Push the wired contact into the insulating block until it stops and
snaps into place.
3. Ensure its correct mounting by slightly pulling on the contact.
4. The male contacts are solid for their entire length and are inserted
with the contact tip first into the rear of the inlet/plug.
5. The female contacts consist of a flexible braid and spring and are
inserted with the contact tip first into the rear of the lidded receptacle/
connector.
6. Insert the Provided Hole Plugs into the unused holes in the front of
each insulating block. NOTICE: If a new Receptacle or Inlet is to
mate with a previously installed device, pay particular attention to the
number of contacts and numbered position in the Receptacle or Inlet.
Continuity will not be obtained unless the male and female contacts
are appropriately mated.
Disassembly of Contacts
1. To remove the contact from the insulating block, the provided
Multi-Contact Removal Tool 61-CA593 must be used. From the front
side of the insulating block, slide the contact removal tool over the
contact.
2. Push until the contact pops out the back side of the insulating block.
3. NOTICE: Each contact is designed to be removed from the insulating
block a maximum of 3 times. New contacts should be used if contacts
are removed more than 3 times.
Voltage Labels
Always have a qualified electrician complete the installation and
apply the supplied voltage labels that best describe the voltage
application level.
WARNING: For safety reasons, it is always recommended to use a ground WARNING
wire. Please reference your local codes for specific electrical requirements.

Mounting Accessories
CAUTION
When fastening the device to the mounting accessory, please use the
screws provided with the mounting accessory. When installing onto poly
mounting accessories, a torque of 10-15 in-lb should be applied. When
NOTICE
installing onto a metallic mounting accessory, a torque of 15 in-lb should be
applied.
Assembly for In-Line Connections (DSN/DS)
When DSN and DS Multipins are used as in-line connectors, finger
drawplates should be installed on both the receptacle and plug in order for
the user to more easily provide the leverage required to connect the device.
Bushing
Compression
Nut
Cable Entry
Devices mounted to the end of a cable require a MELTRIC
handles are provided with either a molded-on or factory installed cord grip.
Assembly for In-Line Connections using a Handle with a Molded-On
Cord Grip (All)
Adjust the bushing diameter to fit the cable by removing inner sections of it
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 drawplate gasket and 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
25/64" and twist the strands of each conductor together.
Verify that the cable sheath 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 compression nut to secure the cable.
Assembly for In-line Connections using a Factory Installed Cord Grip
Factory installed cord grips are installed with the appropriate torque. When
tightening the compression nut the cord grip should be held with a wrench
or pliers to avoid transferring torque through the cord grip body to the
handle. See Figure C
Poly handles provided with a ½" NPT cord grip (12 conductor and 24
conductor part numbers containing a "B", Ex. 711P0BP6) should have a
torque of 33.3 in-lb applied to the compression nut. All other poly handles
should have a torque of 66.4 in-lb applied to the compression nut.
Metallic handles provided with a ½" NPT cord grip (12 conductor part
numbers containing a "B", Ex. 791P0BS3) should have a torque of 55.3
in-lb applied to the compression nut. All other metallic handles should have
a torque of 88.5 in-lb applied to the compression nut.
Stainless steel handles should have torque applied to the compression
nut that is adequate to prevent slipping, but not in excess of the values
indicated in the table below. The letters B, C, D, and E in the handle part
number indicate the NPT size of the cord grip. Ex. 7X3P0DS1

OPERATION (DSN/DS)
CAUTION
Connection
NOTICE
To connect a plug and receptacle, first depress the pawl 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
latch on the receptacle casing. 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. The electrical connection is now made.
On in-line connectors, squeeze the drawplates on both sides of the device
together until the plug latches in place.
Disconnection
To break the connection, simply depress the pawl as shown in figure 3.
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 figure 4 . Close and latch the lid on the receptacle.
Connection and Disconnection of Stainless Steel DS
Operation of the stainless steel DS is similar to the standard DSN operation
with the following two exceptions:
1. The stainless steel DS utilizes two pawls to latch the plug to the
receptacle. Thus to disconnect the plug from the receptacle both
pawls must be depressed.
2. The stainless steel DS24c plug casing does not have a red dot that
can be used for proper alignment before insertion. Instead, the thicker
groove in the plug casing should be aligned with the thicker
protruding screw in the receptacle and the thinner groove should be
aligned with the thin protruding screw.
3. The stainless steel DSN37c casings do not utilize red dots for
alignment. For proper alignment before insertion, align the arrow on
the plug with the "off" position on the receptacle.

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.
NOTICE: MELTRIC
The use of fitting seal tape is required to maintain watertightness of all NPT
fittings and joints.
Lockout Provisions
PN and DSN 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 optional hole provided in the pawl. This will
prevent the lid from being opened for the insertion of a plug. This feature is
not available on SS devices.
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.
