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.
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.
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

∗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.
3.3 Wiring
Open the terminal cover and connect the supply conductors. If
Tais < 45°C, use 75°C rated wire; if Tais > 45°C use
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

-22°F to +131°F (-30°C to +55°C). screw. Insert entry fitting through the enclosure hole, tighten
into the bonding plate and secure with locknut. Connect the
2.3 Storage temperature range:
-67°F to +212°F (-55°C to +100°C). bonding jumper to the terminal marked . A second 1" NPT
bottom fitting can be installed by removing the close-up plug
2.4 Environmental protection: IP 66 / Type 3, 4, 4X.
Covers must be tight when plug is not inserted to maintain
environmental protection. Observe the labels on the plug and
and installing a 1" NPT fitting with locknut in it’s’ place. See
Parts and Accessories.
