2 Mounting

2.1 Location Requirements

• Location in the existing electrical circuit varies with the application and the type of switch.

• Location and wiring must comply with the contract drawings.

• There must be a service disconnect in the commercial power line ahead of the transfer switch.

• Choose a vibration-free mounting surface that supports the weight of the switch.

• Avoid locations that are near flammable liquids or gases, or are hot, moist, or dusty.

WARNING

An electrical arc occurs during transfer that can ignite a flammable atmosphere, resulting in

severe personal injury or death. The switch must not be located near batteries, fuel tanks,

solvents, or other sources of flammable liquids or gases, or in areas sharing ventilation with

such sources.

2.2 Wall Mounting

1. Check the location to be sure that no wires or plumbing, gas, or exhaust lines run behind the wall.

2. Install two mounting bolts in the wall for the top cabinet mounting keyholes.

3. With the shipping box standing so the cabinet is upright, carefully remove the top and sides of the

box.

4. Raise the cabinet and mount it on the two mounting bolts in the wall.

WARNING

Improper lifting can cause severe personal injury. Have sufficient manpower for lifting and

mounting the cabinet.

5. Install two bottom mounting bolts, but do not tighten. (Do not remove the cabinet support until all

bolts are installed.)

6. Push the cabinet against the wall. If the cabinet does not align flush against the wall, shim the

mounting bosses as required.

7. Tighten all mounting bolts.

2.3 Seismically Certified Installations

Seismically certified transfer switch installations (feature code A080-7) have special requirements, as

defined by IAA-VMC (Independent Approval Agency, the VMC Group).

1. The design of post-installed anchors in concrete used for the component anchorage; is prequalified

for seismic applications in accordance with AC1 355.2 and documented in a report by a reputable

testing agency (for example, the Evaluation Service Report issued by the international Code

Council).
