Southern States EV-2 Installation Reference Manual

INSTALLATION REFERENCE GUIDE 1 This guide is intended to be used as a recommended sequence of work steps but does not supersede the instruction manual (IB-101-EV2) or assembly drawings. For assistance, contact the Southern States Service Division (available 24/7) at 770-946-4565. MOUNT PHASES PER ENGINEERING DRAWINGS 3 6 PIERCE VERTICAL BEARING SET-SCREW COMPLETELY NOTE: This will be the only piercing until step 13. Ensure the full weight of the vertical pipe is supported by the vertical bearing and maintain the gap required between the coupling and gear operator. Then pierce collar. Also, confirm auxiliary arm assembly is correctly mounted per the operating mechanism drawing. INSTALL ADJUSTABLE ARM & DRIVE PHASE CLEVISES Typical Mounting Bolt Locations Refer to operating mechanism drawing for pole orientation and mounting Vertical Bearing Set Screw (Pierce Bolt) Drive Phase Clevis Adjustable Arm Refer To Instruction Book Section: Installation & Adjustment Procedures Refer To Instruction Book Section: Installation & Adjustment Procedures Refer To Instruction Book Section: Installation & Adjustment Procedures REVIEW BILL OF LADING (BOL) A. Check the materials received against the packing list B. Report any shortages or damaged equipment to Southern States 2 REVIEW BILL OF MATERIAL (BOM) A. Inventory all parts against the BOM found on the op-mech sheet inside the drawing package B. Report any missing or damaged parts to Southern States TERMINOLOGY OVERVIEW A: Live Parts B: Insulator C: Base D: Jaw E: Blade F: Counterbalance G: Contact Fingers H: Switch Operating Arm I: Bearing J: Arcing Horns A B C C. A typical shipment will include: - 3 phase switch (base, insulators, & live parts) - Operating mechanism box - Operating pipe MOUNT VERTICAL BEARING, PIPE, & OPERATOR 4 1/4” to 3/8” gap Vertical Bearing Support Vertical Pipe Operator Refer To Instruction Book Section: Installation & Adjustment Procedures 5 7 CONNECT & TIGHTEN DRIVE PIPE BETWEEN ADJUSTABLE ARM & AUXILIARY ARM OF DRIVE PHASE WITH APPROPRIATE CLEVISES Refer To Instruction Book Section: Installation & Adjustment Procedures NOTE: DO NOT PIERCE UNTIL STEP 13 8 MATCH-MARK CLEVIS CONNECTIONS, ADJ. ARM, & OPERATOR COUPLING TO MONITOR SLIPPAGE Refer To Instruction Book Section: Installation & Adjustment Procedures Drive Pipe D E F G H I J Mounting Bolt Locations Vertical Bearing Support Special Handling Required - A qualified rigger and lift plan are required due to possible off center, high, center of gravity. Lift by switch base only. WARNING SLING ATTACHMENT Publication No. QSG101-EV-2 R0 12172020 SECURE BLADE WITH TIES DURING LIFTING Because the phase is top heavy, the base must be bolted to the structure before removing lifting straps to prevent tipping. CAUTION Note: All material is marked with JO number Vertical Pipe

C. Blade must enter center of jaw G. Reach rod on op-mech should be toggled (snapped in) when it reaches the full closed position (toggle in full open position also preferred if possible) 11 IF ADJUSTMENTS ARE STILL NEEDED, REFER TO STEPS BELOW BASED ON THE SWITCH AND OPERATOR POSITION: 10 INSTALL INTERPHASE PIPE CONNECTING DRIVE PHASE WITH OTHER TWO PHASES - SECURE WITH CLEVIS BOLTS & ADJUST 12 ENSURE REMAINING TWO PHASES FULLY CLOSE AND OPEN PER STEP 11 GUIDELINES 13 FINAL CHECK & ASSEMBLY B. Test operate to ensure specification is met. D. Pierce all set-screws. E. If motor operator is being used, ensure limit switches are set. F. Ensure all accessories from the op-mech package are installed (ground shunt, VM-1 swing handle, etc.). A. Install any and all switch accessories (whips, interrupters, MACI ®, arcing horns, etc.) per their assembly drawings. All three phases should now be in adjustment. If a phase blade angle adjustment is needed, you can loosen the stop bolt / jam nut to adjust the open angle. Contact SSLLC if further adjustment issues occur. F. Blade angle must be at least 90O in the full open position if horizontally mounted (70O for vertical and underhung mounting) 9 Loosen Bolts/Adjust Pipe & Arm Once the interphase pipe is installed, test operate. If step 11 criteria are not met, loosen interphase clevis and adjust by 1/4” increments as needed. Ensure the switch is fully closed by pushing on the lever arm, then re-tighten the clevises. Refer To Instruction Book Section: Installation & Adjustment Procedures Refer To Instruction Book Section: Installation & Adjustment Procedures Refer To Instruction Book Section: Installation & Adjustment Procedures A. Blade contacts should be centered front to back B. Contact fingers must be centered on the blade tip in the full closed position D. Contact bar must be within “+” or “-” 5 degrees from flat in the full closed position E. Blade must fully rest on the blade stop inside the jaw in the full closed position NOTE: FOR ARCING HORN ADJUSTMENTS, REFER TO INSTRUCTION MANUAL IF Operator Reaches Full Open Position & Switch Is Not Fully Opened: • Check for slippage • Return switch to almost closed but not toggled • Match-mark adjustable arm and pipe clevis • Lengthen both the adjustable arm radius & pipe clevis by 1/4” increments until full switch opening and operator rotation is achieved IF Switch Is Fully Opened Before Operator Reaches Full Open Position: • Check for slippage • Return switch to almost closed but not toggled • Match-mark adjustable arm and pipe clevis • Shorten both the adjustable arm radius & pipe clevis by 1/4” increments until full switch opening and operator rotation is achieved Refer To Instruction Book Section: Installation & Adjustment Procedures C. Land conductors to terminal pads and retest switch. Readjust switch if necessary. Refer To Instruction Book Section: Installation & Adjustment Procedures
