1Operation Instructions MN650047EN May 2017
CAUTION
Eaton’s Cooper Power series 600 A T-OP II™ terminator
is designed to be operated in accordance with normal
safe operating procedures. These instructions are not
intended to supersede or replace existing safety and
operating procedures.Terminators must be de-energized
during operation or maintenance. Visible break and
adequate grounding must be provided before cable
work proceeds.
T-OP II terminators should be installed and serviced only
by personnel familiar with good safety practice and the
handling of high-voltage electrical equipment.

Operation
Isolating and grounding a cable requiring repair
Step 1
De-energize cables
 Open switches at both ends of cable to be isolated.
(Refer to Figure 4.)
 Determine that there is adequate working room around
the terminators for parking the insulated standoff
bushings and training cables.
 Determine that there is adequate working room for
handling hotstick around apparatus cabinet.
 Place insulating rubber blanket on the ground directly in
front of terminators.
 Inspect and test all operating equipment for serviceability.
 Connect grounding elbow of appropriate voltage class, to
system ground.
 Connect ground leads of protective caps to system ground.
Figure 4. De-energized cables
Step 2
Determine that cables are de-energized
 Remove 200 A protective cap or arrester from T-OPII
terminators using hotstick and set aside in a clean,
protected area.
 Insert test probe of phasing stick on volt meter into 200
A interface. (Refer to Figure 5.)
 Determine that all cables are de-energized.
Figure 5. Test for voltage with phasing sticks
WARNING
Do not proceed until cables are de-energized.
Step 3
Provide a visible break
 Clean and lubricate T-OP II insulated standoff bushing.
 Mount T-OP II insulated standoff bushing in the apparatus
parking pocket using a hotstick. Tighten eyebolt to
ensure secure mounting. Ensure that the copper stud is
properlyinstalled in the bushing before moving cable.
(Refer to Figure 6.)
Figure 6. Mount T-OP II standoff bushing
 Clean and lubricate, mating interface of the O&T/Torque
tool with an approved lubricant.
 Grasp eye of the O&T/Torque tool with a hotstick, pull eye
fully into the stick.

 Using the hotstick, insert the O&T/Torque tool into the
throat of the 200 A bushing portion at the LRTP. Engage
the rotating nut. (Refer to Figure 7.)
 Turn the O&T/Torque tool counterclockwise until both the
threaded connection and the interference fit of the T-OP
II is broken.

ote:N The initial disconnect of the T-OP II may be difficult
until the installation torque is overcome.
 Using the hotstick, lift the T-OP II termination off the
apparatus bushing and place it on the insulated standoff
bushing. (Refer to Figure 8.)
 While pushing the T-body onto the standoff bushing, turn
the O&T/Torque tool clockwise to make the threaded
connection, turn until tight.
 Remove O&T/Torque tool.

Step 4
Provide a visible ground
 After securing cable end of grounding elbow to the
system ground, firmly grasp the pulling eye of the elbow
with the hotstick.
 Close the grounding elbow into the 200 A bushing of the
LRTP. (Refer to Figure 9.)
 Attach drain wire of 600 A T-OP II protective cap to
system ground.
 Clean and lubricate mating interface of cap.
Figure 9. Install the grounding elbow into the
200 A bushing
 Grasp pulling eye of cap with hotstick and pull fully into

exposed apparatus bushing by threading the cap on to
the bushing stud.
 Turn until tight and remove hotstick.
 Repeat this procedure on both ends, for each cable to
be grounded. (Refer to Figure 10.

switch if it is closed. (Refer to Figure 11.)
 Grasp 600 A protective cap with shotgun. Rotate
counterclockwise, until threads are disengaged.
 Remove protective cap from the bushing and set aside in
a clean, protected area.
 Using, a volt meter, test apparatus bushing to determine
that the bushing is de-energized. (Refer to Figure 12.)
WARNING
Do not proceed until apparatus is de-energized.
Figure 12. Test for voltage with volt meter
Step 2
Connect cable to apparatus bushing
 Grasp pulling eye of the grounding elbow with shotgun,
pull firmly to remove elbow from the LRTP of the T-body.
 Set elbow aside in a clean area.
 Grasp O&T/Torque tool with the shotgun and pull fully
into hotstick.
 Using the shotgun, insert the O&T/Torque tool into the
throat at the LRTP and engage the rotating nut. Rotate
tool counterclockwise until both the threaded connection
and the rubber interference fit is broken.
 Lift the T-OP II termination from the insulated standoff
bushing to the apparatus bushing.
 While pushing the T-body on to the apparatus bushing,
turn the O&T/Torque tool clockwise to make the threaded
connection. Turn until torque head rachets (20-25 ft-lbs.).
An audible click will be heard. (Refer to Figure 13.)
