INSTALLATION, OPERATION & MAINTENANCE DATA SHEET
VSQ SERIES 30 AMP INTERLOCKED SWITCHED RECEPTACLES
APPLICATIONS
•
VSQ series dead front interlocked receptacle with
switch is suitable for use in hazardous locations.
•
Designed for supplying power to fixed or portable
electrical equipment.
ELECTRICAL RATING
•
Maximum voltage - 600 VAC @ 50-400Hz.
Continuous Current - 30Amperes.
INSTALLATION
•
Carefully Read and understand the following
instructions before installation & operation of this
device.
•
Note: All Installations must comply with Applicable
Local, National Electrical Code and/or Canadian
Electrical Code.
•
Note: VSQ covers can not be used on VWSQ
mounting boxes, which are intended for nonhazardous location installations.
•
Warning: Make sure the receptacle assembly is
suitable for use in desired location per applicable local
and/or National Electrical Code. Serious damage
and/or injuries may result due to improper
applications. Electrical power must be turned OFF
before and during the installation & maintenance.
Fatal injury and/or damage may result by not
following these instructions.
•
Mounting Arrangement: Receptacle assembly must
be mounted securely onto a column, wall, or other
structure that is able to support the device and the
associated conduit system. The structure is to be
prepared for use of four (4) 3/8” steel bolts (furnished
by others) using the lugs on the housing. The
spacings are as shown in Fig. 1. The device is
equipped with factory installed hinges. It must be
mounted with the hinges on the bottom and the
receptacle in the downward direction.
•
Conduit Installation:
1.
1” NPT conduit entries are provided on the top and
bottom of the housing.
2.
All conduit entries must be sealed within 18” of the
enclosure as per National Electrical Code.
3.
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 sufficient length of supply
conductors to connect to the enclosed terminals.
3.
Strip the conductors to the length shown in table.
4.
Loosen the switch terminal screws and wrap the
stripped conductors securely around the terminal
screws. Tighten the terminals to the torque specified
in the table.
4. Connect the conductors to the ground and phase
terminals securely and tighten to the values shown in
the table.
•
Inspect & Clean Flange: The machined flange
surface of both the box and cover must be smooth,
free of nicks, scratches, dirt, or any foreign particle
build-up that would prevent proper seating. Surfaces
must seat fully against each other to provide a proper
flame path joint. Clean surfaces by wiping with a
clean, lint free cloth. Apply a light coating of “LUBG”
lubricant to flange surface.
•
Cover Securement: Close the cover then install and
tighten all cover bolts to 25 ft.-lb. Make sure no cover
bolts are omitted. Use only those bolts supplied with
the device. Check the bolted joint with a .0015” feeler
gauge. The gauge must not enter the joint more than
1/8” at any point.
•
Caution: Missing bolts or an improper joint can result
in an explosion, creating the potential for serious or
fatal physical injury and/or property damage.
•
Cover Replacement: The power must be
disconnected before removing the cover. Remove the
bolts and reverse the wiring procedure. Once the
conductors have been detached, remove the screws
that hold the cover to the hinges (4 total). Line up the
new cover with the hinges and reinstall the hinge
screws. Once the hinges are attached repeat the
wiring, inspect & clean flange and cover securement
procedures.

OPERATION
•
Caution: The switch cannot be turned ON without
fully inserting an approved plug (see list below). A
plug cannot be inserted or withdrawn unless the
switch is OFF. To remove the plug turn the switch to
the OFF position and pull back on the locking pin
knob while pulling on the plug.
•
Note: Switch cannot be operated until the locking pin
has fully engaged the plug.
ROUTINE INTERLOCK VERIFICATION
•
Warning: Perform this test before energizing the
receptacle.
•
Before inserting the plug verify that the switch can
not be turned to the ON position.
•
Insert the plug, turn the switch to the ON position, pull
on the locking pin knob and verify that the plug can
not be withdrawn without turning the switch to the
OFF position.
•
If the receptacle does not perform
properly
discontinue use immediately!
ELECTRICAL TEST
•
Warning: Perform this test before energizing the
receptacle.
•
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.
MAINTENANCE
•
Electrical and mechanical inspection of all
components must be performed regularly. It is
recommended that an inspection be performed a
minimum of once a year.
•
Inspect all terminals for tightness (Retorque).
Discoloration due to excessive heat is an indicator of
possible problems and should be thoroughly
investigated and repaired as necessary.
•
Inspect grounding and bonding for correct installation
and secure connection (Retorque).
•
Warning: 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.
•
Inspect gaskets for deterioration and replace if
necessary.
•
Clean exterior surfaces making sure nameplates
remain legible.
•
Torque all bolts and screws as described in the
instructions before reusing the device.
•
Inspect 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.
