Summary & Introduction
Introduction
Southern States 550kV Type EV-1 is a heavy duty, single phase (Pole) operated vertical break air
disconnect switch. The switch is specifically designed to carry the mechanical and electrical stresses
of higher voltage and amperage ratings. The switch can be operated using a manual operator or
electrical motor operator. The installation procedure for this disconnect switch and operating
mechanism is explained herein.
Note: All drawings in this manual are for illustration only. Actual switch components may differ slightly
in appearance. Switch operating mechanism drawings must be used for assembly of each switch.
The installation procedure for all mounting positions and operating schemes is similar and explained
herein. A system of pipes, bearing, and adjustable length arms is utilized to open and close the switch
from a ground level operator.
The instructions contained within this manual are necessary for the safe installation, maintenance,
and operation of the Type EV-1 switch. A qualified person, familiar with this of type equipment, should
carefully read and follow the instructions.
These instructions are intended to provide a general guideline for the installation, adjustment, and
maintenance of the Type EV-1 switch. It is not possible to cover all details, equipment variations, and
potential conditions. Contact Southern States, LLC in the event conditions associated with a specific
application are not sufficiently addressed.
All photographs and sketches in this manual are for illustration purposes only and may not be to scale.
Refer to the Unit Assembly drawing or the Operating Mechanism drawing provided with each
disconnect switch for specific details. During installation, it may be necessary to make adjustments
other than those described in this manual. Contact your local representative or the factory if questions
should arise.
Southern States After Sales and Service Department is available for field installation assistance along
with providing parts support for all Southern States products.

Typical Disconnect Switch
In general, installing a disconnect switch consists of the following:
•Refer to the Unit Assembly drawing included with the disconnect package for assembling
disconnects.
•Assemble disconnect switch on level surface, verify the switch base is perpendicular and level.
•Mount the insulators to the switch base. Verify that insulators are plumb (straight up and down)
and rotating insulator is true (No “Wobble”).
•Mount the live parts to the insulators. Verify that live parts are level and shim or adjust if
necessary.
•Mount the switch base to the structure. Refer to the Operating Mechanism Drawings for
structure and mounting details.
•Install operating mechanism components.
•Final adjustment and tuning.

Receiving, Handling & Storage
Receiving, Handling & Storage
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.
If damage or a shortage is noted, file a claim immediately with the carrier and contact the factory.
Storage
All components of the EV-1 vertical break disconnect switch are suitable for outdoor use and do not
have any special storage requirements. Keep bearings out of standing water. Keep upright and
support live parts with base. If a motor operator is furnished, be sure to connect the heater circuit
using the provided external wiring, while the unit is in storage. Discard the wiring upon installation.
Typical crating is intended for storage of less than 1 year. If long term storage is required please
notify factory at time of order placement so that special crating can be used.

Removal of the Live Parts
1. Open the switch completely by manually rotating the switch arm clock-wise.
2. Make reference marks (Match-marks) as shown in Figure 1to ensure correct orientation
during reassembly.
Failure To Open The Switch Completely Prior To Removing The
Mounting Bolts May Result In Severe Injury And/Or Death

Installation & Adjustment Procedures
Figure 1 - Switch Match-marks
3. To remove the jaw (Clip), remove the bolts holding the jaw to the base adaptor and retain all
of the ½” spacer(s). (See Figure 6)
4. Remove the bolts holding the hinge and yoke assembly. Carefully remove these parts as a
unit and set aside.
Mounting the Base
It is preferable to assemble the disconnect switch on the ground, but if this is not possible. Install
the switch base on top of the structure prior to mounting the insulators and live parts.
Mounting the Insulators
1. Prior to installing insulators on the base, verify that you have the correct insulators on hand
((2) PX0792 & (1) PX0794)) each consisting of a bottom, middle and top section.
2. Level the mounting plate (Figure 2“C”) prior to mounting the insulator on the switch base.
3. Mount the insulator to the mounting plate (4 bolts).
4. Use a plumb line and minimum 3’ level to insure that the insulators are level.

Installation & Adjustment Procedures
Rotating Insulator Adjustment
1. For proper adjustment of the rotating insulator for concentric rotation (Wobble) please refer to
Figure 3& Figure 4.
2. Refer to Figure 2
a. To adjust the insulator stack angles, loosen four nuts (B). Tilt the insulator to the
required position by screwing up or down on nuts (A). Mounting plate (C).
Figure 2: Insulator Adjustment

Page 9 of 20
Installation & Adjustment Procedures
Figure 3: Method for locating center of rotating insulator cap
STEP ONE
Use a piece of scrap lumber or metal
and attach it to the top of the non-
rotating insulator to use for a reference.
Place the point of the lumber/metal over
the center of the rotating insulator. The
rotating insulator should be up against a
bearing stop
(Full open or closed
position).

Page 10 of 20
Installation & Adjustment Procedures
Figure 4 – Adjusting the Rotating Insulator for Concentric Rotation
Do Not Re-Adjust the center stack once it rotates true. Make all subsequent adjustments to
the other two insulator stacks as required.
STEP TWO
Rotate the insulator to the opposite
bearing stop. Observe for eccentric
rotation (“wobble”).
STEP THREE
If during rotation the insulator has
wobbled, leave it against the bearing
stop in step two. Use the jacking bolts
mounting the rotating insulator to the
bearing to tilt it back ½ the distance to
the reference point on the marker.
STEP FOUR
Rotate the insulator back to the starting
position. Loosen the marker and place the
reference point over the center of the
insulat
or again. Repeat the last three
steps until the insulator rotates true. (Up
to 1/4” wobble is acceptable.) This
method works whether the rotating
insulator is out of adjustment axially,
laterally, or any combination in between
