Page 15: Receiving, Handling & Storage
Page 6 of 25 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 16: 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 17: 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-1V 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 Page 9 of 25 Installation & Adjustment Procedures A – Male Contact B – Blade Stop Figure 2: Contact Assembly 8. Preload the insulator as described under “Insulator Preload” in the following section. 9. If arcing horns are used, refer to Figure 3 and the unit assembly drawing for installation. Arcing horns should rub against the male contact with enough pressure to maintain contact but not so hard as to cause binding.

Page 10 of 25 Installation & Adjustment Procedures Installation of the EC-1V When Shipped Unassembled 1. Prior to assembly, all components should be checked for any obvious damage in shipment. If damage is noted, immediately file a claim with the carrier and notify the factory. - Page 20 Page 11 of 25 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 21 Page 12 of 25 Installation & Adjustment Procedures Jack Screws: Adjustment of switches consists mainly of getting the insulators properly aligned, which is easily accomplished with jack screws. Jack screws should be adjusted in pairs and equally. For example, to tilt the insulator in the direction of the arrow, loosen both nuts “B”...

Page 22: Contact Misalignments
Page 13 of 25 Installation & Adjustment Procedures Contact Misalignments Check for proper blade alignment. The blade segments should meet on centerline of base, on center of each other and the stop plug centered and touching (not jamming) the male contact stirrup (Figure 6). - Page 23 Page 14 of 25 Installation & Adjustment Procedures A. Misalignment “B”: Jack the left insulator to the right and the right insulator to the right until the stop plug is centered on the stirrup. Adjust insulators one at a time and in equal increments.

Page 27: Final Switch Adjustments (Tuning)
Page 18 of 25 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 180 o ± using an operator (manual or electrical). The interphase pipe controls the individual operation of each switch pole, using a push/pull control. - Page 28 Page 19 of 25 Installation & Adjustment Procedures 2.2. Worm gear operator (SEGO – Safety Enhanced Gear Operator) (Optional) 2.2.1. The weight of the vertical operating pipe should be supported by pipe collar by maintaining the ¼”-3/8” gap. 2.2.2. When the switch is properly adjusted the operator handle should hang freely in both the open and closed positions to permit the use of the customer supplied padlock.
- Page 29 Page 20 of 25 Installation & Adjustment Procedures 3. Preliminary Switch Settings: 3.1. Start with the disconnect switch and operating mechanism in the closed position. 3.1.1. The switch is in the fully closed position when the centerline of the male blade assembly is aligned with the centerline of the Female Blade Assembly.
- Page 30 Page 21 of 25 Installation & Adjustment Procedures 4.5. If the switch has too much toggle in either open or closed position, loosen the pipe clevis and adjust to allow for an equal toggle amount in both positions. 4.6. All poles of the fully adjusted disconnect switch should operate together, although a slight vari¬ance between poles is acceptable.

Page 31: Changing Disconnect Opening Direction
The following are instructions for making field modifications to the opening direction of the disconnect switch if it is determined that it is necessary. If parts or assistance are required please contact your Local Representative or Southern States Service Division, contact information provide on the back page. - Page 32 Page 23 of 25 Installation & Adjustment Procedures a. Leave the operator in the starting position as originally shown on the operating mechanism drawing. b. To achieve CLOCKWISE handle rotation to OPEN you must attach the adjustable arm 180 degrees from its original setup. The pipe clevis will also need to be rotated to the opposite side of the adjustable arm (side closest to the structure) but with the radius of the clevis still pointing toward the disconnect switch.

Page 33: 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 34: Patrolling Inspection (6 Months)
Page 25 of 25 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 35 THIS PAGE LEFT INTENTIONALLY BLANK...
