IMPROPER POWER CABLE CONNECTIONS CAN
CAUSE EXCESSIVE HEAT GENERATION AND
SUBSEQUENT EQUIPMENT FAILURE.
BUS CONNECTIONS
All interconnecting bus between the ATSBI Switches
have been assembled at the factory and require no
additional attention during the installation process.
In connecting power supply bus, use grade 5
hardware for the bolted connection to the
bypass switch terminal plates located at the rear
of the unit. Insure that the bus surfaces to be
joined are clean and free from dirt or other
foreign substances. A nonflammable solvent
may be desirable for cleaning the bus if
required. Tighten connecting hardware per table
2.

HARNESSES
The ATS Power Panel, ATS Logic Panel, and B/I
Panel are interconnected via a number of
preassembled wiring harnesses. These harnesses
are terminated in keyed plug/socket connectors. All
plug/sockets are engaged at the factory prior to
Energizing the equipment. The plug/sockets are
keyed to only permit proper insertion alignment by
pushing the plug into the socket until the latches
click.
ENGINE START CONNECTION
The engine control contact connections are located
on the ATS Switch. NOTE: Prior to making the
engine start connection to the ATSBI equipment, set
engine generator controls selector switch in the Off
position to prevent an unwanted engine start
condition. Connect the engine start wires to the
RED terminal blocks marked 51A and 52A. A contact
closes between these terminal blocks when an
engine start signal is provided by either the ATS or
Bypass logic. See wiring diagram supplied with the
equipment for additional start connection
information.
AUXILIARY CIRCUIT CONNECTIONS
Additional auxiliary control circuit connections may
be required on the ATSBI equipment in specific
applications. Such connections could include:
Standard position indication contacts, optional
accessories 14,24,33 and 35, and other special
connections specifically supplied for your
application. Refer to wiring diagrams supplied with
the equipment for connections identification.
PRELIMINARY CHECKS
After the ATSBI enclosure is installed and power
cables are connected to the equipment, make a
thorough inspection of the unit to insure no tools are
left inside and that the cabinet is free of debris. If
necessary use a vacuum cleaner to remove any and
all construction or installation debris from the
equipment.
Read and understand all labels affixed to the
equipment. Give specific attention to the operation
instruction label and schematic diagram affixed to
the enclosure front cover. See Fig. 3. Review and
understand the composite wiring diagrams supplied
with the equipment. Note any optional accessories
that may have been furnished with this unit and
review their operation. Make all necessary ATS logic
and accessory adjustments as indicated in the
controller manual.
