The DR products are manufactured and rated in
compliance with applicable UL and CSA standards.
The products ratings are indicated on the device labels.
Some DR, DR7 and DS7 devices are provided 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 secure cord gripping.

loosening due to wire strand settlement, vibration
and thermal cycling. NOTICE: They should not
be over-tightened. Appropriate tools and
tightening torques are indicated in Table 5.
5. 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 these products are used as in-line connectors, WARNING
finger drawplates (or a drawbar mechanism) should be
installed on both the receptacle and plug in order for DANGER
the user to more easily provide the leverage required
to connect the device.

AVISO
Adjust the bushing diameter to fit the cable by
removing inner sections of it as required. Insert the
bushing into the strain relief, then insert the assembly
into the handle and loosely install the compression
nut. Insert the cable through the handle, the thin black
drawplate 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 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 their respective
terminals and tighten the terminal screws with the
appropriate tool to the torque
indicated in Table 5.
Verify that the cable sheath 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.

Insert the cable or wires through the wall box and
cut to allow adequate length, strip the cable sheath
as desired, 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 their respective terminals and hand tighten the
terminal screws to the torque indicated in Table 5.
Assemble the receptacle (or inlet) and the color-
coded gasket to the box with the appropriate hardware.
Assemble the mating plug (or receptacle) to the cord
end as indicated in the assembly instructions above
for in-line connections, except there will be no finger
drawplate or associated black gasket.
