General description Introduction Siemens type Vector® manual groupoperated air switch is precision built equipment designed to function efficiently under normal operating conditions. It is designed and manufactured to operate within the parameters established in ANSI/ IEEE and NEMA standards for disconnecting and load-interrupter switches. Performance requirements of these standards have been met or exceeded by these designs. Specific standards which apply include: ANSI/IEEE C37.
General description Scope These instructions cover the installation, operation and maintenance of a Siemens type Vector® manual group-operated air switch. The equipment designs described in this instruction manual consists of group-operated air switch for application up to 38.0 kV. A typical type Vector manual group-operated air switch is shown in Figure 1. All diagrams, descriptions and instructions apply to all of the above classes and designs unless noted otherwise.
Receiving, handling and storage Receiving Pipe guide assembly Each type Vector® manual group-operated air switch is securely blocked and braced for shipment on a pallet. It is crated, boxed or covered as required by shipping conditions. If special handling is required, it is so indicated. The type Vector manual group-operated air switch must be handled carefully when unloading.
Receiving, handling and storage 3. A ny visible damage must be noted on the delivery receipt and acknowledged with the driver’s signature. The damage should be detailed as much as possible. It is essential that a notation "possible internal damage, subject to inspection" be included on delivery receipt. If the driver will not sign the delivery receipt with damage noted, the shipment should not be signed for by the consignee or their agent. 4.
Receiving, handling and storage Lifting and moving There are a number of methods that can be used in handling the type Vector® manual group-operated switch that, when properly employed, will not damage the type Vector manual group-operated switch. The handling method used will be determined by conditions and available equipment at the installation site. The lifting method used in handling the type Vector manual group-operated switch is achieved via the single point hoist bracket.
Installation Installation Installation instructions for the type Vector manual group-operated air switch are detailed in the following steps: A 1. Drill two mounting holes 11/16" in diameter located per the user's construction standards and spaced per Siemens assembly drawing. 2. Install the mounting bolts in the holes. Mounting bolts to be furnished by others. 3. Using the single-point lift bracket, lift the air switch approximately 4' (1.

A grounding point (1/2-13 tapped hole) is provided in the side of the mounting bracket (refer to assembly drawing provided). 10.
Operating handle adjustment procedure Operating handle adjustment procedure The next series of steps address adjusting the position of the handle assembly and lock segment assembly so that the handle can be inserted into the OPEN and CLOSED slot correctly. Important: It is extremely important to adjust the handle position so it is impossible to place the operating handle in the CLOSED slot unless the air switch blades are fully closed.

Operational check out instructions 2. As the blade continues to rotate open, the interrupter lever must make full metal-to-metal contact with the contactor (refer to Figure 13: Contactor connection). At this point, the load then transfers from the auxiliary contacts to the interrupter's lever arm so that the interrupter now carries the full load. 3. As the blade continues to rotate open, the interrupter will trip thus interrupting the load.
Maintenance Maintenance Maintenance instructions for the type Vector® manual group-operated switch are detailed in the following steps: 1. P eriodically operate the switch and check for actions described in Operational check out instructions on pages 14-15. Lubricate the jaw, auxiliary contacts and the end of the blade with Dow Corning® Molykote FS1292 white grease. 2.
