Page 14: Receiving, Handling & Storage
Page 5 of 22 Receiving, Handling & Storage Receiving, Handling & Storage These switches are top-heavy and unstable unless bolted down. To prevent personnel injury or equipment damage, use extreme care when uncrating. Unpacking Unpack the equipment and check for damages or material shortages immediately. The bill-of-material from the Unit Assembly (switch) and Operating Mechanism drawings should be used for this purpose. -
Page 15: Installation & Adjustment Procedures
Contact your local representative or the factory if questions should arise. Southern States Service Department is available for field installation assistance along with providing parts support for all Southern States products. -
Page 16: Preferred Switch Assembly Method
Installation consists of mounting the switch pole on the structure and installing the operating linkage. These instructions give the general procedure for adjusting EC-2V switches. It may be necessary to make adjustments not described in the manual. If any questions should arise concerning the installation or adjustment of its equipment, please call your local Southern States representative or the factory direct. -

Page 18: Contact Misalignments
Page 9 of 22 Installation & Adjustment Procedures 5. Place counterbalance arm directly on the other bearing hub and other intrapole arm on top. Be certain the angle between the two arms is set correctly. Bolt insulators directly to the intrapole arm plate. - Page 19 Page 10 of 22 Installation & Adjustment Procedures Figure 4: Misalignment “A” A. Misalignment “A”: Jack the left insulator to the left and the right insulator to the left until the stop plug is centered on the stirrup. Adjust insulators one at a time and in equal increments.
- Page 20 Page 11 of 22 Installation & Adjustment Procedures Figure 7: Misalignment “D” D. Misalignment “D”: The stirrup striking the trailing edge of the female contact is the result of the intrapole linkage being too short. Lengthen this linkage as required for smooth closing without interference or dragging.

Page 25: Final Switch Adjustments (Tuning)
Page 16 of 22 Installation & Adjustment Procedures Final Switch Adjustments (Tuning) 1. The operating mechanism is intended to fully open and fully close the disconnect switch by rotating the vertical operating pipe about 180 using an operator (manual or electrical). The interphase pipe controls the individual operation of each switch pole, using a push/pull control. - Page 26 Page 17 of 22 Installation & Adjustment Procedures Be aware that there is an adjustable stop on the operator. Do not over operate as damage will occur to the operator. Figure 15: Type SEGO (Safety Enhanced Gear Operator) 2.3. Swing handle operator 2.3.1.
- Page 27 Page 18 of 22 Installation & Adjustment Procedures 4.1. Before making any adjustments always check that none of the pinned joints have slipped. If slippage occurs, correct it and repeat the operation to verify that adjustment is really needed. 4.2. Open the disconnect switch with the operator. The switch is in the fully open position when both blades are approximately 90 to the switch base.
- Page 28 Page 19 of 22 Installation & Adjustment Procedures the closed position, because this will help to prevent the disconnect switch from trying to open during a fault condition. 4.8. Final Check: 4.8.1. Once all final adjustments are complete, be sure that all nuts are tightened to their specified torque (Refer to Table 2).

Page 29: Recommended Inspection Maintenance
Recommended Inspection Maintenance Recommended Inspection Maintenance Southern States’ disconnect switches are designed to operate with minimum maintenance. While disconnecting switches are not readily serviced at frequent intervals, periodic inspection is important for satisfactory operation and maximized overall life. Frequency of inspection and maintenance depends on the installation site, weather, atmospheric conditions, experience of operating personnel, and any special operation requirements. -
Page 30: Patrolling Inspection (6 Months)
Page 21 of 22 Recommended Inspection Maintenance Patrolling Inspection (6 Months) The patrolling inspection is a largely visual inspection on an energized unit in service. The frequency of the inspection is determined by the local conditions and policies of the owner of the equipment. Inspect the insulators for breaks, cracks, burns, or cement deterioration. - Page 31 Page 22 of 22 Recommended Inspection Maintenance Comments:...
