TP-6447 10/1216 Section 2 Installation
2.5 Controller
Hazardous voltage.
Will cause severe injury or death.
Disconnect all power sources before
opening the enclosure.
DANGER
NOTICE
Electrostatic discharge damage. Electrostatic discharge
(ESD) damages electronic circuit boards. Prevent
electrostatic discharge damage by wearing an approved
grounding wrist strap when handling electronic circuit boards
or integrated circuits. An approved grounding wrist strap
provides a high resistance (about 1 megohm), not a direct
short, to ground.
The controller’s logic board is mounted in a plastic
housing on the inside of the transfer switch enclosure
door.
2.5.1 Controller Connection
Verify that the contactor harness is connected to the
controller (through the logic disconnect switch, if
equipped). See the controller Operation manual. See
list of Related Materials in the Introduction for document
numbers.
Note: Verify that the power is disconnected before
connecting or disconnecting the contactor
harness.
2.5.2 Controller Ground
Verify that the grounding wire is connected from the
controller to the stud on the door and to the inside of the
enclosure. This connection provides proper grounding
that does not rely upon the door hinges.
2.5.3 Other Connections
Refer to the transfer switch wiring diagram or the
controller Operation Manual for the following controller
and accessory connections.
D Inputs and outputs
D Communications connections
D Accessory connections
2.6 Electrical Wiring
The transfer switch is factory-wired and tested. Field
installation includes connecting the sources, loads,
generator start circuit(s), and auxiliary circuits, if used.
Note: An approved protective device such as a
molded-case circuit breaker or fused disconnect
switch MUST be installed on both sources of
incoming power for circuit protection and use as a
disconnect device.
Refer to the wiring diagrams provided with the transfer
switch. Observe all applicable national, state, and local
electrical codes during installation.
Install DC, control, and communication system wiring
in separate conduit from AC power wiring.
Accidental starting.
Can cause severe injury or death.
Disconnect the battery cables before
working on the generator set.
Remove the negative (--) lead first
when disconnecting the battery.
Reconnect the negative (--) lead last
when reconnecting the battery.
WARNING
Disabling the generator set. Accidental starting can
cause severe injury or death. Before working on the
generator set or connected equipment, disable the generator
set as follows: (1) Move the generator set master switch to the
OFF position. (2) Disconnect the power to the battery
charger. (3) Remove the battery cables, negative (--) lead
first. Reconnect the negative (--) lead last when reconnecting
the battery. Follow these precautions to prevent starting of the
generator set by an automatic transfer switch, remote
start/stop switch, or engine start command from a remote
computer.
Hazardous voltage.
Will cause severe injury or death.
Disconnect all power sources before
opening the enclosure.
