Eaton TMCX Terminator II Manuel D'installation Et Maintenance

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/TC-ER/TC-ER-HL 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 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.
WARNING
To avoid risk of electrical shock, electrical power must be OFF
before and during installation and maintenance.

RECOMENDATIONS 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 maintaining
earthing. It can be Eaton's Crouse-Hinds series type HTL or STL
lubricants.
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.
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.

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 should be removed from
the exterior tapered surface of the sealing chamber
immediately.
3. The sealing chamber should 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. If either surface is scratched, marred, corroded
or otherwise damaged, do not reassemble. Replace the
fitting.
5. After packing sealing chamber with TSC, be sure to allow
compound to harden before moving conductors.
5. Disassemble union nut and remove rear assembly from thread
body.
IF 1647
5a. For Chico LiquidSeal installation: remove electrical tape and
separate conductors. Mix liquid compound per included
instructions. Hold cable gland upright and pour liquid compound
until it reaches the top of the compound chamber. Wiggle and
separate conductors to make sure compound settles between
conductors; use a hardwood stick or dowel if needed to work
around larger cable bundles. 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 Chico LiquidSeal installation with dispenser cartridge: follow
mixing instructions included with the cartridge, then follow the
pouring instructions from 5a.
5c. 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).
