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

General Notes & Precautions
1. This product must be installed by 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 required 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.
INSPN P
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 3. 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 4.
