QWI-DMCP-7.3-003 Rev “B“ Page 4 of 13 Ground Connector Fitting Installation Procedure
1.0 INTRODUCTION DMC Power Ground Connector fittings are used to join permanent electrical connections on copper conductors used in substation grounding for the electric utilities and the like. The connection is achieved by means of mechanically compressing a DMC Power Ground Connector fitting over the copper conductor using DMC Power Swaging Tools. The DMC Power Swaging Tools consist of a power unit, head assembly, and a hydraulic pump. The DMC Power Swaging Tool is activated by 10,000 Psi which is provided by the hydraulic pump. The power unit has a piston inside the power unit which is connected to the die block (shown in figure 1). The die block holds one swage die while the head holds another swage die. The Swage Tool is placed over the fitting after the DMC Power Ground Connector fitting is placed over the bare copper conductor. When the pump is activated, the piston inside the power unit will extend with the die block which swages the Ground Connector fitting onto the bare copper conductor. The swage is then checked using an inspection gauge.
The purpose of this manual is to provide instructions for the proper installation of the DMC Power Ground Connector fittings using DMC Power Swage Tools.
2.0 TRAINING DMC Power provides optional training at no additional cost to the customer. Training courses are designed to teach personnel how to properly install DMC Power Ground Connectors and operate DMC Power Swage Tools. The training will be conducted by a certified instructor or by an authorized DMC Power representative.

3.0 DMC POWER SWAGE TOOLING SYSTEM The DMC Power Tooling System consists of the DLT Power Swage Tool, DMC Power Ground Connector fitting, and a hydraulic pump. The DMC Power Swage Tool which is used to swage bare copper conductors sizes 1/2, 1, 1-1/4, 1-1/2, 1-7/8, 2, 2-1/4, and 2-3/4 inches is shown in figure 1 (table 1 shows the conductor size). There are 2 types of hydraulic pumps that can be used with DMC Power Swage Tools (refer to table 1).
CAUTION: THE EQUIPMENT USED IN SWAGING IS SUBJECTED TO HIGH PRESSURE. IMPROPER USE MAY RESULT IN TOOL FAILURE AND/OR SERIOUS PERSONAL INJURY.
IT IS NOT SAFE TO APPLY HYDRAULIC PRESSURE WHEN THE HEAD ASSEMBLY IS NOT ENGAGED WITH THE POWER UNIT.

4.0 INSTALLATION PROCEDURE
4.1 CUT AND CLEAN THE END OF THE BARE COPPER CONDUCTOR Cut the bare copper conductor so that the strand ends are even. Clean an area of 2-1/2 inches from the end of the conductor using a wire brush.
4.2 ASSEMBLING THE DMC POWER GROUND CONNECTOR FITTING Insert the bare copper conductor until it bottoms out making sure that the conductor is visible through the inspection hole as shown in figure 2.
Figure 2: Fully inserted conductor in the DMC Power Ground Connector fitting.
4.3 ASSEMBLING THE DMC POWER SWAGE TOOL Mount the Die Block onto the Power Unit and make sure it is locked in place with the pushpin. Slide the Power Unit and Head together. Properly align the Head and the Power Unit such that the face is flush as shown in figure 3.

4.4 SWAGING THE DMC POWER GROUND CONNECTOR FITTING Position the Swage Tool as shown in figure 4 ensuring that the Swage Dies’ teeth are aligned between then fitting end and the swage line. Start the Hydraulic Pump to actuate the tool. Swaging is complete when the Die Block makes contact with the Head and the pressure reaches 10,000 psi. Disengage the Head from the Power Unit once the Die Block fully retracts.

5.0 TOOL MAINTENANCE This section covers regular inspection and cleaning of the DMC Swage Tools. The quick disconnects and hoses are all rated for 10,000 psi and are not to be substituted. In handling the tools, do not hold tools by the quick disconnect or the hose.
Refer to table 3 for Preventive Maintenance.
PROCEDURE FREQUENCY
Ensure the swivel is secured tightly. Before each use
Ensure the quick disconnect is tight and works properly. Before each use
Ensure the piston is retracted to its lowest position. Before each use
Ensure the head sliding areas are free of dirt and damage. Before each use
Ensure the pushpin in the die block is operating properly and ensure the die block engages properly with the piston.
Before each use
With the Head Assembly attached to the Power Unit, actuate the Swage Tool a few times.
Before each use
Check swage dies for foreign material between slots and for any cracks. Clean the dies using a wire brush to remove metal chips accumulated between the slots of the dies. Clean the head and die block.
Before each use
Apply DMC Power Swage Lube on head and lower die block. Frequently, after dies and head are cleaned.
Perform die penetrate inspection on the cylinder and head At lease once a year Table 3: Preventive Maintenance.

DMC Power Ground Connector Assembly Instructions
Step 1: CUT AND CLEAN THE END OF THE COPPER CONDUCTOR Confirm that the DMC Power Ground Connector fitting matches the cable or rod size. Also, confirm that the Swage Tool matches the Ground Connector fitting size. Cut the copper conductor so that the strand ends are even. Clean an area of 2 inches from the end of the conductor using a wire brush.
Step 2: ASSEMBLE THE DMC POWER GROUND CONNECTOR FITTING WITH THE COPPER CONDUCTOR Insert the copper conductor into the Ground Connector fitting making sure that the conductor is visible through the inspection hole as shown in figure 1.
Step 3: ASSEMBLE THE DMC POWER SWAGE TOOL Mount the Die Block onto the Power Unit and make sure it is locked in place with the
pushpin/setscrew. Slide the Power Unit and Head together.
Step 4: CONNECT THE HYDRAULIC PUMP TO THE POWER UNIT Connect the DMC Power Swage Tool to the hydraulic pump via the quick disconnect (threaded or push-pull) fitting to the hydraulic hose line. Properly align the Head and the Power Unit such that the face is flush as shown in picture 2.
Step 5: PERFORMING A SWAGE
Position the Swage Tool over the DMC Power Ground Connector fitting. Ensure that the Swage Dies’ teeth are
aligned between the end of the fitting and the Swage Line mark as shown in figure 1. Start the Hydraulic Pump to
actuate the tool. Swaging is complete when the Die Block makes contact with the Head and the pressure reaches
10,000 psi. Disengage the Head from the Power Unit once the Die Block fully retracts.
Step 6: INSPECT THE SWAGED CONNECTOR FITTING Use the Inspection Gauge (figure 2) to verify that the swage is good by positioning the Inspection Gauge
on the swaged portion of the fitting as shown in picture 3. If there are no Inspection Gauges available, refer to table 1 for “Depth of Swage” dimension for the swage inspection.
REPEAT STEPS 1 THROUGH 6 FOR EACH GROUND CONNECTOR FITTING END.
