INSTALLATION
PN Series plugs and receptacles should be
installed by a qualified person in accordance
with all applicable local and national electrical
codes.
Before starting, verify that the power has been
disconnected, all product ratings are appropriate
for the application and the conductors meet code
requirements and are within the capacities of the
terminals noted in Table 2. NPT Guidelines are
detailed in Table 3.

General Notes & Precautions
INSPN J
1. This product must be installed by a certified
personnel.
2. NOTICE: Do not tin terminal wire ends.
3. NOTICE: Do not use moisture repellent sprays on
the contacts.
4. Do not back terminal screws fully out.
5. Self-tapping screws are provided for use with some
polymeric accessories. High torque may be
required to drive them in. NOTICE: Once they
are seated, care should be taken in order to avoid
over-tightening them against the plastic material.
6. NOTICE: Meltric threaded handles come with
tapered style threads. The use of fitting seal tape
is recommended to maintain watertightness of
all NPT fittings and joints.
7. Various handles and cord grip options may be
used. These instructions are based on handles
provided with integral multi-layer bushing cord grips.
8. If the plug and receptacle are stainless steel then
stainless steel accessories must be used.
ENVIRONMENTAL
Optimum operating conditions are achieved by installing
IP66/IP67 plugs and receptacles with the latch at the top.
NOTICE: To prevent water ingress, non-watertight plugs/
receptacles must always face downwards when not mated.
Wire Strip Length
Wire strip lengths are indicated in Table 4. Strip
lengths for cable sheathing will depend on the
specific application. When used with handles, the
cable sheathing should extend into the handle to
ensure secure cord gripping.

Terminal Screw Tightening Torques
The wiring terminals are spring-assisted to prevent
loosening due to wire strand settlement, vibration and
thermal cycling. NOTICE: Avoid over-tightening. Appropriate
tools and tightening torques are indicated in Table 5.

Wiring the Terminal Connections
Verify that power has been disconnected prior to
wiring the conductors to the plug and receptacle.
Wiring must be made according to all applicable
local and national electrical codes. Check that
the rating is correct for the installation.
Follow the conductor-coding and terminal markings
detailed in Table 6. WARNING: This product must
be electrically grounded. A grounding terminal is
provided on all metal accessories, with a green screw
and a washer.
For Screw Type Terminals
Insert cable through handle and strip cable jacket to
adequate length. The cable jacket should extend at
least 1/2" into handle. Back out terminal screws only
far enough for conductor to clear. Strip each conductor
per Table 4. Twist the strands of each conductor
together and insert fully into the terminal. Tighten
terminal screws to torques indicated in Table 5.
PN12c Crimped/Soldered Terminal Wire Connections:
1. Strip each conductor to 25/64-inches (10-mm).
2A. For 18-16 AWG wires, insert Ferrule into contact.
2B. For 14 AWG Wires (max), the Ferrule is not required.
3. Insert stripped wire end into Ferrule or contact.
(Perform either step 4 or 5)
4A. 18-16 AWG Wires – 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).
4B. 14 AWG Wires – For Crimping the Contacts,
use either North American Contact Crimping Tool
4CN30 (using crimping slot 8) or Crimp contact
with European Contact Crimping Tool 61-CA500
(using 4 MM slot).
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.
NOTE: Sleeve must be applied.
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 PN12c 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.
