Installation Instructions

LINK---C

DEADBREAK CAM LINK OPERABLE CONNECTOR SYSTEM

The Link is a 600 amp, connector designed to: 1.) provide a fully shielded, fully submersible hot stick operable connection
between the cable and the apparatus. 2.) provide 200 ampere tap, for 15kV and 25kV.

WARNING: The following ratings apply to this product:

600 Ampere Deadbreak Interface --- 600 or amperes load current and 25,000 amperes short circuit

current for 10 cycles.

200 Ampere Loadbreak Interface --- 200 amperes load current and 10,000 amperes fault--- close current.

For higher short circuit current: 1) thisinterface should only beoper --­ated de---energized; and 2) elbows used for taps or grounding must
be adequately secured such as with a bail.

DANGER

All apparatus must be de--energized during installation
or removal of part(s). For loadbreak products follow
operating instructions. All deadbreak connectors must
be de--energized before operating. All 200A deadbreak
connectors must be mechanically secured with bails
when connected.

All apparatus must be installed and operated in
accordance with individual user, local, and national
work rules. These instructions do not attempt to
provide for every possible contingency.

Do not touch or move energized products.

Excess distortion of the assembled product may result
in its failure.

FOR MORE INFORMATION ON PARTS, INSTALLATION RATINGS AND COMPATIBILITY, CALL THE NEAREST ELASTIMOLD OFFICE.

Inspect parts for damage, rating and compatibility with
mating parts.

This product should be installed only by competent
personnel trained in good safety practices involving
high voltage electrical equipment. These instructions
are not intended asa substitute foradequate training or
experience in such safety practices.

Failure to follow these instructions will result in
damage to the product and serious or fatal injury.

If this product is supplied with a protective shipping
cover(s), remove this shipping cover(s) and replace
with the appropriate HV insulated cap(s) or
connector(s) before submerging or energizing the
circuit.

IMPORTANT

1. Check contents of package to ensure they are complete
and undamaged.

2. Check all components to ensure proper fit with cable
and/or mating products.

3. Read entire installation instructions before starting.

4. Have all required tools at hand and maintain cleanliness
throughout the procedure.

STEP 1

Install the 600 amp elbow onto the cable according to the installation instructions supplied with the elbow, such that it will
align with the stand ---off plug.

STEP 3 MOUNTED STAND---OFF PLUG INSTALLATION (Where Applicable)

1. Weld studs to faceplate per customer standard practice to dimenisons shown. Studs to be 3/8 ---16 x 2” long.

2. Check prepack for the following: 6 hex nuts and 3 lockwashers.

3. Install the 3 hex nuts onto the 3 studs per the dimensions indicated or use (3) spacers (not supplied).

IMPORTANT: The 3 hex nuts are needed to support the stand ---off plug so that it is in---line with the bushing. These
supports (nuts) may not be needed if the bushing in your application are welded Elastimold bushings.

4. Install SOP over the 3 studs and resting on the nuts or spacers.

5. IMPORTANT: Install lockwasher and hex nut on each of the 3 studs and tighten to 12 foot lbs torque.

The top surfaces of the bushing and stand---off plug must be in---line, if not re---adjust the nuts as required.

STEP 4

1. Clean and lubricate the apparatus bushing and both interfaces of the 600 amp bushing extender with ELASTIMOLD

supplied lubricant. IMPORTANT: Bushing extender interfaces must be thoroughly lubricated to allow for proper
removal of the link.

2. Install bushing extender onto the apparatus bushing. Insert the 600ATM into the retainer contact and engage the
internal hex broach.

3. Insert the retainer contact into the bushing extender and thread into apparatus bushing using a suitable tool applied to
the 1” hex portion of the 600ATM, torque to 50--60 ft--lbs.

4. Clean and lubricate the epoxy standoff plug and both interfaces of the 600 amp elbow with ELASTIMOLD supplied
lubricant. IMPORTANT: Elbow interfaces must be thoroughly lubricated to allow for proper removal of the link.

5. Install the elbow onto the epoxy standoff plug. Insert the 600AMT into the retainer contact and engage the internal hex broach.

6. Insert the retainer contact into the 600 amp elbow through the hole in the compression lug and thread into the epoxy
standoff plug using a suitable tool applied to the 1” hex portion of the 600AMT, torque to 50--60 ft--lbs.

STEP 8

1. The elbow must begrounded. Feed a #14 AWG or #12 AWG solid copper wire throughthe groundingeye on the elbow,
twist tight and connect to ground.

2. Clean and lubricate the 200 amp interface on the Link.

3. Ground, then install the desired mating product on the 200 amp interface per the installation instructions supplied with
the mating product.

4. The cable must be grounded:

D if concentric neutral cable is used, twist the concentric neutral wires together and connect to ground using an

appropriate connector.

D if 20MA or 21MA grounding devices are used, connect the ground lead from the 20/21MA device to ground

using a suitable connector.

For three-- phase installations all grounds from all three phases must be tied to a common ground point.
