Emerson 7ATB Installation, Remove Shipping Brackets / Angles From the Transfer Switch, Mounting

Page 5

SECTION 1 INSTALLATION

The ASCO 7000 Series Automatic Transfer & Bypass–Isolation Switch (ATB) consists of an upper bypass–isolation switch, a lower transfer switch, a monitoring and transfer controller, and door–mounted controls. The ATB is factory wired and tested. Installation requires removal of the shipping skid then securing the enclosure to the supporting foundation.

Remove Shipping Brackets / Angles

from the Transfer Switch

Open the lower front door(s). The Transfer Switch carriage is secured to the frame for shipment. Remove the three or four shipping brackets or L–angles (1 upper left, 1 upper right, 1 lower right, or 2 lower on 4000 A).

Remove the Shipping Skid

Open the front lower door and remove the two front lag screws securing the enclosure to the wood skid. Next remove the rear lower panel and remove the two rear lag screws securing the enclosure to the wood skid.

To prevent serious damage, remove 3 shipping angles from the transfer switch carriage. Do not turn the Isolation Handle until they are removed!

Supporting Foundation

The supporting foundation for the enclosure must be level and straight. Allow at least 35 inches in front of the enclosure for draw out of the Transfer Switch.

Refer to the enclosure outline drawing included with the ATB for all mounting details including door opening space.

If bottom cable entry is used, the foundation must be prepared so that the conduit stubs are located correctly. Refer to the appropriate enclosure outline drawing for specified cable entrance area and location. Provide cable bending space and clearance to live metal parts. When a concrete floor is poured, use interlocking conduit spacer caps or a wood or metal template to maintain proper conduit alignment.

Mounting

Refer to the enclosure outline drawing furnished with this switch and mount the 7000 Series ATB according to the details and instructions shown on the drawing.
