For Hazardous and Corrosive Applications
Please read this entire document
before beginning any work.
1. Safety Instructions
Installation and maintenance of these plugs and receptacles
should only be performed by skilled and experienced
personnel in accordance with the National Electrical Code
(NEC) (NFPA 70) and any local regulations which relate to
hazardous (classified) locations.
CAUTION:
∗ Disconnect power supply before installing or servicing
these plugs and/or receptacles.
∗ A modification to this product, other than noted on this form,
is not permitted.
∗ Operate only undamaged and clean plugs & receptacles with
observations of the operating parameters in section 2.
∗ For a Class I Zone 1 conduit installation, conduit seals are

conduit installation NO seals are required.
∗ Use only approved wiring methods for the location, with the
associated conduit/cable fittings.
∗ The receptacle is suitable for use on a circuit capable of
delivering not more than 10,000 rms symmetrical amperes,
600V maximum, when protected by properly sized Class J
fuses.
2. Technical Data
Please refer to the technical data on the nameplates.

3. Receptacle Installation
3.1 Enclosure mounting
Securely mount the receptacle in a vertical position using four
1/4" (6 mm) screws and suitable washers. Dimensions are
marked on the back of the receptacle housing.
3.2 Conduit/Cable Installation
For conduit installation, connect rigid conduit to the hub and
avoid misalignment.
For cable installation, connect a listed cable fitting.
Conduit or cable fittings should not be tightened more than 50
ft-lbs (68 N-m) of torque.
3.3 Wiring
Open the terminal cover and connect the supply conductors. If
is < 45°C, use 75°C rated wire; if T
T
a
is > 45°C use
a
90°C wire. The terminals accept up to two wires which are 14
AWG through 8 AWG per terminal. Allow proper length for
bending and cut the conductors to length. Strip the conductor
insulation 13/32" (10 mm) from the end. Insert the conductors
into the appropriate terminals which are marked to correspond
with the markings inside the plug. Torque all terminal screws to
16 in-lbs (1.8 N-m); including all unused terminals.
3.4 Installation of Auxiliary Contact Block (optional)
One or two blocks, either for I.S. or
non-I.S. circuits can be installed by
snapping them into either side of the
main terminal block. These contact
blocks also can be retrofitted and
must be installed according to IOM
Form No. K1289. See Parts and Accessories for block types.
3.5 Installation of Additional Entries
Additional top and side wiring entries can be installed in the
receptacle by punching through hole(s) 1-3/8" nominal dia. for
1" NPT. Use the mounting kit P/N YOST8571801290. The kit
contains one brass bonding plate, two locknuts with two 1"
NPT threaded holes and one bonding jumper with connection
screw. Insert entry fitting through the enclosure hole, tighten
into the bonding plate and secure with locknut. Connect the
bonding jumper to the terminal marked . A second 1" NPT
bottom fitting can be installed by removing the close-up plug
and installing a 1" NPT fitting with locknut in it’s’ place. See
Parts and Accessories.

5. Wiring of Plug VSI30P
5.1 Cord Type
Select a flexible cord with copper conductors of the
appropriate insulation, ampacity, and temperature (75°C or
90°C) rating. For installations in the U.S., refer to the
NEC, section 400.4, 400.5, 501.140, 502.140 and 503.140.
NOTE: Cords with O.D. between 0.6" and 1.1" can be
used. Maximum wire range for plug terminals is 1 x
14 AWG up to 1 x 8 AWG.
5.2 Cord Preparation
Cut the cord cleanly - Do not strip away cord jacket or
conductor insulation at this time.
5.3 Opening the Plug
Referring to Figure 1 above, loosen screws (1) and remove
the plug housing
(2). Then unscrew the compression collar
(3) and remove the close-up disc (4) and discard it. Then
remove the friction washer (5) and grommet (6).
5.4 Insert the Cord
Guide the compression collar (3) and the friction washer (5),
over the cord.
5.4.1 Install Cord Grommet
The grommet (6) is a universal onion ring style which
accommodates several cord diameters by removing (cutting
out) the inner undersized diameters. The grommet should fit
snugly on the cord. The grommet may require lubrication in
order to slide over the cord. Use talcum powder or an
equivalent material rated for use on electrical products. Slide
the grommet over the cord with the cuts toward the plug
housing (2).
NOTE: If the grommet slides freely over the cord, there will be
insufficient sealing for Class II and Class III Hazardous
Locations.
5.4.2 Install Strap and Plug Housing on Cord
Slide the strap ring (8) and the plug housing (2) over the
cord.
5.5 Cord Preparation
Dress the cord by removing the outer jacket and fillers for a
length of 2 ½" (63 mm) and strip 2 ½”
the insulation off of each ½”
conductor a distance of ½"
(12 mm) from the end.
Figure 1
5.6 Connection to Terminals
Flip the strain relief (7) out of the way. Attach the leads to the
appropriate terminals and torque with 16 in-lbs (1.8 N-m).
CAUTION: The Equipment Grounding Conductor (green wire)
is to be connected to the terminal marked
.
5.7 Strain Relief
Open the clamp (7) and adjust the clamping size to the O.D. of
the cord (this may require removing 1 or 2 of the clamp inserts,
if necessary). Then flip the strain relief back and clamp the
cord using 14 in-lbs (1.6 N-m) torque.
5.8 Plug Assembly
Rejoin the two parts of the plug enclosure paying careful
attention to the orientation of the alignment tap and reinstall
the three screws (1). Slide the grommet (6) into position in the
receiving cavity of the plug housing, then place the friction
washer against the grommet and turn on the compression
collar until a good compression is achieved.
6. Maintenance
The only maintenance is a periodic inspection for damage and
proper operation. The surface of the plug pins and the pin
chamber should be kept clean. Keep cap (9) on plug when not
in use. Any damaged equipment should be replaced promptl y
to ensure the electrical safety and explosion protection of the
system.
