Controller Ground
A grounding wire must be connected to the controller’s
lower left mounting stud. Be cause the controller is
mounted on the enclosure door, a conductive strap must be
used between the enclosure and t he door. This connection
provides proper grounding which does not rely upon the
door hinges.
Harnesses
The transfer switch is connected to the left side of the
controller by a plug–in harness (two plugs).
Auxiliary Circuits
Connect auxiliary circuit wires to appropriate terminals on
transfer switch. Note the control features that are fur-
nished on this switch. Make the necessary auxiliary
connections by referring to Section 5, Control Features.
Functional Test
The Functional Test consists of three checks: manual
operation, voltage checks, and electrical operation.
Do these checks i n the order presented to
avoid damaging the automatic transfer switch.
!
Read all instructions on the Wiring Diagram and labels
affixed to the automatic transfer switch. Note the control
features that are provided and review their operation
before proceeding.
1 – Manual Operation Test
A manual oper ator handl e (detachab l e on 225 – 400 amp.
sizes) is provided on the Transfer Switch for maintenanc
e
purposes only
. Manual operation of the transfer switch
should be checked before it is energized (operated
electrically).
Do not manually operate the transfer switch
until both power sources are disconnected:
open both circuit breakers.
