GENERAL
PN, DSN and DS Multipin products are used for power
and control. They can carry loads as well as low level
signals and information. These multipin devices comply
with applicable IEC standards.
Please follow the instructions below to ensure the proper
installation, operation and maintenance of this product.
There are inherent dangers
WARNING
associated with electrical
products. Failure to follow
DANGER
safety precautions can result in serious injury or death.
These instructions must be followed to ensure the safe
and proper installation, operation and maintenance of
the MELTRIC CAUTION
® devices. Before installation, disconnect
all sources of power to the circuit to eliminate the risk of
electrical shock.
NOTICE

INSTALLATION
PN, DSN and DS Multipins should be installed by
ADVERTENCIA
qualified electricians in accordance with all
applicable local and national electrical codes.
DANGER
Before starting, verify that the power is off, that the
product ratings are appropriate for the application, and
WARNING
CAUTION
that the conductors meet code requirements and are
within the capacities of the terminals noted in Table 1.

Bonding of Metallic Components
Where required by code, typically systems exceeding 50V,
the casing and corresponding metallic accessories must
be bonded to the ground contact.
The PN12c, and DS37 are provided with two bonding
leads. The shorter lead is to be terminated to the ground
contact, the longer lead terminated to the mounting
accessory. The ground conductor from the cable should
be terminated to the ground screw on the mounting
accessory. See Figure A
A
The DS24 is provided with a four-port terminal "wire
nut" assembly. The terminal block is provided with 2
pigtails installed. The shorter lead is to be terminated at
the ground contact, the longer lead is to be terminated
to the mounting accessory. The remaining 2 ports are
for connecting the lead from the device casing and
terminating the ground conductor from the cable.

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
(in AWG)
1
terminal for approximately 30 seconds.
While heating, apply the soldering wire into the hole
Maximum
at the bottom of the terminal and let it penetrate by
14 capillary action. Let it cool down without any
mechanical stress.

6. Slide the Heat Shrink Insulation Sleeve over
14
the contact until it butts up against the contact
14
shoulder.
14
NOTICE: Sleeve must be applied to maintain
14
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.
Assembly Disassembly
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 wire. Please reference your local codes for
WARNING
specific electrical requirements.
Mounting Accessories
DANGER
When fastening the device to the mounting accessory,
please use the screws provided with the mounting
CAUTION
accessory. When installing onto poly mounting
accessories, a torque of 10-15 in-lb should be applied.
When installing onto a metallic mounting accessory, a
torque of 15 in-lb should be applied.
NOTICE
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.

Cable Entry
Devices mounted to the end of a cable require a

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
