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 and DSN Series Switch Rated plugs & receptacles
are UL & CSA listed in accordance with UL 1682,
Subject 2682 and CSA 22.2 182.1. All are listed as
CAUTION
'Branch Circuit Disconnect Switches', are horsepower
rated, and listed as 'Motor Circuit Disconnect Switches'.
AVISO
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.

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.

5. Wiring terminals are spring assisted to prevent
loosening due to wire strand settlement, vibration
and thermal cycling. NOTICE: Do not over-
tighten the terminal screws. Appropriate tools
and tightening torques are indicated in Table 5.
6. Some auxiliary contacts are factory prewired.
Proper lugs should be used and lugs should be
crimped with the proper tool.
7. NOTICE: MELTRIC threaded handles come with
tapered style threads. The use of fitting seal tape
is recommended to maintain watertightness of
all NPT fittings, joints. To maintain environmental
protection use listed cord grips.

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

provide the leverage required to connect the device.
On the larger sized devices, (DS100, DSN150 &
CAUTION
DS200) the finger drawplates are not needed because
an easy closing mechanism is provided as standard.
NOTICE
For poly handles with strain relief, adjust the bushing
diameter to fit the cable by removing inner sections

of the bushing as required. Insert the bushing into the
strain relief, then insert the assembly into the handle

and loosely install the compression nut. Insert the

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
AVISO
must extend into the handle to achieve a secure cord
grip. Then strip the individual wires to the lengths
indicated in Table 4 and twist the strands of each
conductor together.
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.
Verify that the cable jacket 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.
