This device cannot be used as a replacement for
VSQ series or other hazardous location devices.
VSQ & VWSQ covers are NOT interchangeable.
1. APPLICATIONS
• VWSQ series dead front interlocked receptacle
with switch
• Designed for supplying power to xed or
portable electrical equipment.
2. ELECTRICAL RATING
Maximum voltage – 600 VAC @ 50-400Hz.
Continuous Current – 30 Amperes.
Mounting Arrangement:
1. Receptacle assembly must be mounted
securely onto column, wall, or other structure
that is able to support the device and associated
conduit system. Structure is to be prepared for
use of four (4) 3/8” steel bolts (furnished by
others) using lugs in the enclosure spaced as
shown in Fig. 1. Device is equipped with factory
installed hinges. Device must be mounted with
the hinges on the bottom and the receptacle
mounted in downward direction.
Conduit Installation:
1. 1 ½” NPT conduit entries are provided on top
and bottom of the housing.
2. Make sure conduit entries are clean before
installing conduit/close-up plugs/reducers
etc. Killark “LUBG” thread lubricant is
recommended for this application.
Wiring
1. Develop and establish the wiring pattern
for your system. Locations having different
voltages and/or frequencies must not have
interchangeable attachment plugs. Always test
before energizing.
2. Make sure to pull sufcient length of supply
conductors to connect the enclosed terminals.
3. Strip the conductors to the length shown in
table.
WARNING: Use only copper cable or wire for the range
indicated in the table. 75°C rated conductors (minimum).
Wire Range Strip Length Torque
Switch #10 - #8 0.750 inches 20 lb-in.
Ground #16 - #6 0.500 inches 20 lb-in.

4. Loosen switch terminal screws and wrap
stripped conductors securely around the
terminal screws. Tighten the terminals to the
values per table.
5. Connect the ground terminal securely and
tighten to the values shown in table.
Inspect & clean the machined ange joint
surface of both the cover & box. Surface must
be smooth, free of nicks, scratches, dirt, or any
foreign particle build-up that would prevent a
proper seal. Surfaces must seat fully against
each other to provide proper joint. Clean
surfaces by wiping with a clean, lint free cloth.
Apply a light coating of “LUBG” lubricant to
ange surface and close the cover. Install and
tighten all cover bolts to 25 ft. lbs. Make sure
no cover bolts are omitted. Use only those bolts
supplied with the device.
2. OPERATION
CAUTION: The plug assembly cannot be
removed until the handle is in the “OFF”
position. The switch cannot be turned “ON”
without the plug inserted into the receptacle.
NOTE: Refer to the label attached on the
operator housing of the receptacle assembly.
Plug Insertion: While inserting the plug into
the receptacle the release button will snap into
place locking the plug into the receptacle.
Switch Control: The switch can be turned “ON”
when the plug is inserted. The plug is locked
in receptacle when the unit is turned “ON”.
The switch handle can be locked in the “OFF”
position.
Plug Removal: Turn “OFF” the switch. Pull
out the release button while removing the plug
from the receptacle (Refer to the label attached
on the operator housing of the receptacle
assembly).
3. ELECTRICAL TEST BEFORE
ENERRGIZING
Do not connect to power before conducting the
following electrical tests:
• Test continuity of wiring to verify correct
polarity, phasing and grounding connections.
• Measure insulation resistance to be sure the
system does not have any shorts or unwanted
grounds.

WARNING
Electrical power supply MUST BE OFF before
and during installation and maintenance.
DISCONNECT primary power source and LOCK
OUT. Installation and maintenance procedure
must be performed by a trained and competent
electrician.
4. MAINTENANCE
Electrical and mechanical inspection of all
components must be performed regularly. It is
recommended that inspection be performed a
minimum of once a year.
• Inspect all contact wire box terminals for
tightness (Retorque). Discoloration die to
excessive heat is an indicator of possible
problems and should be thoroughly investigated
and repaired as necessary.
• Check grounding and bonding for correct
installations and secure connections
(Retorque).
WARNING
If any parts of the plug, receptacle or switch appear
to be missing, broken or show signs of damage:
DISCONTINUE USE IMMEDIATELY!
Do not modify these devices in any way.
Replace with proper replacement part(s)
supplied by Killark before continuing service.
Failure to do so could cause serious or fatal
personal injury and/or equipment damage.
• Check gaskets for deterioration and replace if
necessary.
• Clean exterior surfaces making sure
nameplates remain legible.
• Inspect clamp guide assembly and cable grip
tightness to ensure proper cable gripping.
• Torque all screws as described in instructions
before reusing device.
• Inspect housing parts and replace those which
are broken or excessively worn.
• Check contacts for signs of excessive arcing or
burning and replace if necessary.
• Check receptacle thread used for plug locking
ring for proper lubrication. Apply Killark “LUBG”
type lubricant or equivalent to thread surfaces
as required to prevent galling between the
receptacle and locking ring threads.
In addition to these required maintenance
procedures, we recommend an Electrical
Preventive Maintenance Program as described
in the National Fire Protection Association
Bulletin NFPA No. 70B.
