Eaton TMCX Terminator II Informations D'installation Et D'entretien

TMCX Terminator™ II cable gland
Installation & maintenance information
SAVE THESE INSTRUCTIONS FOR FUTURE REFERENCE
APPLICATION
TMCX Terminator II cable fittings are designed for use with
™
Type MC/MC-HL jacketed metal-clad cable, interlocked armor
and continuous corrugated armor, TECK, ITC and Type TC
tray cable in hazardous (classified) locations when installed, in
accordance with NEC/CEC. TMCX Terminator II cable fittings
are cULus Listed for hazardous locations (with TSC epoxy
sealing compound and Chico LiquidSeal only) according to UL
®
WARNING
To avoid risk of electrical shock, electrical power must be OFF
before and during installation and maintenance conductors,
and top off if necessary.
RECOMMENDATIONS FOR INSTALLATION
For all versions, suitable grease must be used on the thread body,
union nut and back nut. Suitable grease must be non-setting,
non-metallic, non-combustible and must maintain bonding/
earthing. Eaton's Crouse-Hinds series type HTL or STL lubricants
are recommended.
CABLE PREPARATION
1. Remove jacket (and armor, if applicable) from the cable to
expose a sufficient length of conductors required for the job.
When using Type MC cable, leave a length of armor exposed
as specified in the table below:

Prepare cable. For Type MC, remove all fillers and shielding
back to armor. For Type TC, remove fillers back to cable
jacket. Separate uninsulated ground conductors back to
armor or sheath to allow sealing of individual strands.
1a. For Chico LiquidSeal installation: Use the provided
hardwood stick and Chico X fiber to fill in all of the
internal voids of the cable armor. Be sure to pack the
Chico X fiber tightly in between the conductors and over
the cable insulation. CAUTION: Chico X fiber shall not
extend past cable jacket or armor. SEE PICTURE OF
CABLE ON NEXT PAGE.

standards 514B and 2225, and CSA standard C22.2 No. 174.
They are suitable for use in NEC/CEC Class I, Divisions 1 & 2,
Groups A, B, C, D; Class II, Divisions 1 & 2, Groups E, F, G; and
Class III, when installed in accordance with NEC/CEC, and using
appropriately approved cable.
Explosionproof cable fittings should be installed, inspected and
maintained by qualified and competent personnel.
2. Install TMCX into hub, wrench-tight.
3. Apply electrical tape to tip of conductors, and slide through
integral dam until armor or TC jacket contacts the dam or
armor stop.
4. Tighten back nut wrench-tight and visually inspect that
environmental seal has collapsed 360° around cable jacket. If
desired, use included torque table as a guideline.
CAUTION
To avoid risk of ignition:
1. Tools must not be allowed to damage the tapered flame
path surfaces. Do not handle sealing chambers roughly,
or use tools that might damage or scratch the tapered
surfaces.
2. Any excess sealing compound must be removed from
the exterior tapered surface of the sealing chamber
immediately.
3. The sealing chamber must be fully bottomed to the rear
assembly before assembly to the thread body.
4. Before reassembly, examine the tapered joint surfaces of
the thread body and sealing chamber. Surfaces must seat
fully against each other to provide a proper explosionproof
joint. Remove any dirt or other foreign matter from both
surfaces, including the mating threads. If either surface is
scratched, marred, corroded or otherwise damaged, do not
reassemble. Replace the fitting.
5. After packing sealing chamber with TSC, allow compound
to cure 8 hours before installation.
5. Unscrew union nut and remove rear assembly from thread
body.
5a. For Chico LiquidSeal installation: Remove electrical tape
and separate conductors. Secure the gland with the
sealing chamber up. Mix liquid compound per included
instructions. Pour liquid compound until it reaches
the top of the sealing chamber. Wiggle and separate
conductors to make sure compound settles between
conductors, and top off if necessary. Maintain assembly
in vertical position until compound has gelled. See cure
graph for gel and energizing times. Minimum storage
temperature for LSC is -60°C.

5b. For TSC installation (with cables containing more
than four (4) conductors, Chico LiquidSeal is
recommended): Unscrew and remove sealing chamber,
remove electrical tape and separate conductors.
Mix two-part epoxy sealing compound provided by
kneading and folding until a uniform color is obtained
(approximately 2-3 minutes). Pack a sufficient amount
of compound between and around conductors, using
the length and I.D. of the sealing chamber as a guide
for shaping the compound. Insert conductors into
sealing chamber and slide the sealing chamber down
over the sealing compound. As compound is getting
compressed, use a hardwood stick or dowel to remove
excess compound and prevent it from getting into the
mating threads. Screw sealing chamber into mating
thread and pack more sealing compound from the
top of the sealing chamber, making sure conductors
are properly sealed around, and the sealing chamber
is completely full. Wipe off any compound from
the sealing chamber's exterior immediately. Allow
compound to sufficiently harden before moving
conductors to avoid creating voids. Allow TSC to cure
for 24 hours before energizing equipment. Minimum
storage temperature for TSC is 40°F (4.4°C).
6. Insert the rear assembly into the thread body. Tighten
union nut wrench-tight. Assembly is complete.
