Installation & Adjustment Procedures
Preferred Switch Assembly Method
The Type EC-2V center break Vee switch is normally shipped assembled on insulators. Control
components are packed separately. 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.
1. Prior to mounting preassembled switches on the structure, each pole should be thoroughly
inspected for damage in shipment. If damage is noted, immediately file a claim with the carrier
and notify the factory.
2. Assemble the switch pole on the ground and hoist it to the structure as a complete unit.
4. Test each switch pole for free operation and blade alignment
.
When closed, the blades should
be in a straight line with the bearing stops touching. These stops can be adjusted if necessary.
5. After mounting the switch, shimming the base or other minor adjustments may be necessary.
6.
Using main sling attachment to the switch base only
and auxiliary sling attachment to keep
the switch upright, mount the switches on the structure as shown on the plan view of the operating
mechanism drawing. Be sure to orient each pole with the switch operating arm in the proper
position. When lifting, positively lock the switch closed. This can be done by using clamps, wire,
or straps to keep the switch operating arm (”E” on
) hard against the bearing stop.
To prevent overturning during assembly, the switch base must be securely
attached to a level, stable platform.
Lift fully assembled pole unit by the base only.
DO NOT
lift the pole unit by the
live parts.
