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. The adjustable arm will now rotate toward the structure
instead of away from it.
c. Attach all other items as shown in the operating mechanism drawing.
d. If the mechanism was originally setup for PUSH to OPEN it has now been
changed to PULL to OPEN and vice versa.
3. Horizontally mounted disconnect switches with EVG-1 ground switch – PARTIAL
DISASSEMBLY WILL BE REQUIRED. Please contact Local Representative or Southern
States Service Division immediately. New brackets for the ground switch and a new
main switch operator will be required to make this change.
3.1. Disconnect adjustment
3.1.1. With the disconnect phase on the ground, remove the ground switch and
mounting bracket as a complete assembly.
3.1.2. If the insulators have not been installed, unbolt the live parts from the switch
bearings and flip the paddle arms on each bearing along the long axis of the
switch base. Reinstall all items as described in Error! Reference source not
found. .
3.1.3. If the insulators have been installed, unbolt the male and female blades from the
insulator. Unbolt the insulators from the switch bearings and flip the paddle arms
on each bearing along the long axis of the switch base. Reinstall all items as
described in Error! Reference source not found..
3.1.4. Minor adjustments maybe required to the operating rod to achieve proper open
close operation as described in Section 2 above.
3.2. Ground Switch Adjustment
3.2.1. Rotate the ground switch jaw 180 degrees and reattach to disconnect blade.
3.2.2. Install new support bracket to the switch base. The ground switch must be
installed on the OPEN side of the disconnect. Adjust the jacking bolts on the
bracket until ground switch fits properly into its jaw.
3.3. Operator and Operating linkage adjustment
3.3.1. Both operators must move to the opposite leg(s) of the structure directly across
from their current position
3.3.2. Operator
1. Setup operating linkages as shown in revised operating mechanism
drawings that will be provided.
2. Please note that a new operator will be needed for the main switch. The
ground switch operator is the same.
