GENERAL
DS and DSN Series products are designed to provide
the safety and functionality of a switch with the con-
venience of a plug & receptacle. They can safely be
used to make and break electrical connections and
are an approved 'line of sight' disconnect switch.
There are inherent dangers
WARNING
associated with electrical
products. Failure to follow safety precautions can result
DANGER
in serious injury or death. These instructions must be
followed to ensure the safe and proper installation, oper-
CAUTION
ation and maintenance of the MELTRIC devices. Before
installation, disconnect all sources of power to the circuit
NOTICE
to eliminate the risk of electrical shock.
ADVERTENCIA
RATINGS
DANGER
DS andDSN Series Switch Rated plugs & receptacles
are UL & CSA listed in accordance with UL 1682,
CAUTION
Subject 2682 and CSA 22.2 182.1. All are listed
as 'Branch Circuit Disconnect Switches' and most are
also horsepower rated and listed as 'Motor Circuit
AVISO
Disconnect Switches'. The amperage, voltage,
horsepower, switch and environmental ratings are
indicated on the product labels.
All DS/DSN devices are rated to make and withstand
short circuit currents with appropriate fusing as indi-
cated in Table 1. Some DS and DSN devices are pro-
vided with optional auxiliary contacts that make after
and break before the phase contacts. The ratings for
auxiliary contacts are shown in Table 2.

INSTALLATION
DS/DSN should be installed by qualified
personel in accordance with all applicable
local and national electrical codes.
Before starting, verify that the power is off, that the
WARNING
product ratings are appropriate for the application, and
that the conductors meet code requirements and are

General Notes & Precautions
1. Self-tapping screws are provided for use with
some polymeric accessories. High torque may
be required to drive them in. Once they are
seated, care should be taken in order to avoid
over-tightening them against the plastic material.
2. Various handles and cord grip 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. When used with handles, the
cable sheathing should extend into the handle to
ensure adequate strain relief.

The wire strip lengths noted on Table 4 are reference strip lengths
based on conductors with thinner insulation. Flexible cables with
thicker insulation may need to be stripped back further. Strip the
cable jacket back as necessary to ensure the conductor bottoms
out in the terminal.

WARNING! If these devices are installed in
motor power supply applications, warning
labels may be required to advise users not to
disconnect the device under load. Labels are
provided in the package, but should only be
used when required.
8. 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.

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 most DS/DSN are used as in-line connectors,
WARNING
finger drawplates should be installed on both the
receptacle and plug in order for the user to more easily
DANGER
provide the leverage required to connect the device.
On the larger sized devices, (DS100, DSN150 &
mm CAUTION
DS200) the finger drawplates are not needed because
16
an easy closing mechanism is provided as standard.

NOTICE
For poly handles with strain relief, adjust the bushing
19
diameter to fit the cable by removing inner sections
22
of the bushing as required. Insert the bushing into the ADVERTENCIA
19
strain relief, then insert the assembly into the handle
DANGER
30
and loosely install the compression nut. Insert the
19
cable through the handle, the thin black drawplate
gasket and finger drawplate (if applicable) and the CAUTION
19
color coded gasket. Strip the cable sheath to provide
22
a workable wire length, being mindful that the sheath
19 AVISO
must extend into the handle to achieve a secure cord
24
grip. Then strip the individual wires to the lengths
24
indicated in Table 4 and twist the strands of each
30
conductor together.
30
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
the proper terminals and tighten the screws with the
appropriate tool to the torque indicated in Table 5.
