Installation 1-1

Installation

The ASCO 7000 Series Medium-Voltage Automatic Transfer Switch (ATS) is factory wired and tested.

Refer to the manual from the manufacturer of the metal-clad switchgear for section handling, installation, power connections, and testing.

Supporting Structure

The supporting foundation for the enclosure must be level and straight. Refer to the applicable enclosure outline drawing included with the transfer switch for all mounting details including door opening space.

Mounting

Refer to the outline and mounting diagram and mount the automatic transfer switch according to details and instructions shown on the diagram.

NOTICE

Protect the transfer switch from construction grit and metal chips to prevent malfunction or shortened life of the transfer switch.

Testing Power Conductors

Do not connect the power conductors to the transfer switch until they are tested. Installing power cables in conduit, cable troughs, and ceiling-suspended hangers often requires considerable force. The pulling of cables can damage insulation and stretch or break the conductor’s strands. For this reason, after the cables are pulled into position, and before they are connected, they should be tested to verify that they are not defective or have been damaged during installation.

Line Connections

Refer to the wiring diagram provided with the transfer switch. All wiring must be made in accordance with the National Electrical Code and local codes.

!DANGER

De-energize all conductors, open all circuit breakers, and rack out all voltage transformers before making any connections. De-energize any UPS, station battery system, or any similar system providing standby control power. Be sure that the Normal and Emergency line connections are in proper phase rotation. Place the engine generator starting control in the OFF position. Make sure engine generator is not in operation.

Engine-Generator Control

Connections

All customer connections, including the engine control contact connections, are located on terminal block TB. This terminal block is located on the interior left side of the control section. Refer to the wiring diagram provided with the automatic transfer switch. Connect the engine start wires to the appropriate terminals. See Figure 1-1 and Table A.
