TP-6126 8/02 9Section 2 Installation
2.5 Electrical Wiring
All internal electrical connections are factory-wired and
tested. Field installation includes connecting the
sources, loads, generator start circuit(s), and auxiliary
circuits, if used.
Note: Do not connect the wiring harness to the
controller until instructed to do so in the voltage
check procedure, Section 3.7.2.
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 metal conduit separate from AC power wiring.
It is not necessary to remove pole covers from the
transfer switch for cabling. If you do remove them,
reinstall them carefully.
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.
DANGER
Hazardous voltage.
Will cause severe injury or death.
Disconnect all power sources before
servicing. Install the barrier after
adjustments, maintenance, or
servicing.
DANGER
Making line or auxiliary connections. Hazardous voltage
can cause severe injury or death. To prevent electrical
shock deenergize the normal power source before making any
line or auxiliary connections.
Grounding electrical equipment. Hazardous voltage can
cause severe injury or death. Electrocution is possible
whenever electricity is present. Open the main circuit
breakers of all power sources before servicing the equipment.
Configure the installation to electrically ground the generator
set and related equipment and electrical circuits to comply with
applicable codes and standards. Never contact electrical
leads or appliances when standing in water or on wet ground
because these conditions increase the risk of electrocution.
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.
