2: INSTALLATION INFORMATION

2:1 General

The basic AST3225 transfer switch includes all control wiring connections.

The electrical switchgear should be installed by a certified electrician, and all wiring

to/from the unit should agree with all applicable electrical codes, standards, and practices.

An engine controller or timing module (optional) is usually installed at the engine; this

installation can be performed by the electrician, or by a mechanic competent at engine

wiring. A diagram for wiring up a typical engine controller at the engine is included at

Section 5:4, Page 15

Interconnecting the engine controller or timer module controller to the transfer switch is

done simply with a 5-wire signal cable. We provide 50' as a standard length with each

order, but any length, in 25' increments can be provided upon request, for a nominal

charge.

The "cable assembly" has the transfer switch connector already mounted. Simply install

it in the Relay Board receptacle, pass the bare end through an appropriately located hole

in the enclosure, and run it to the engine controller or timer module. At the controller,

trim the wire to length, strip the color coded wires, and insert them into the appropriate

locations of the 5-pin connector supplied for the purpose. Then connect to the adaptor

harness. (Also supplied.)
