voltage rating is listed on the controller nameplate. Consult your Schneider
Electric representative if the equipment requires modification from these
voltage ratings.
The ATS48 soft start control transformer and overcurrent protective device
(OCPD) may require change or reconfiguration.
• Lock the keypad after making parameter adjustments.
• Do not reset soft start parameters to configurations other than those
specified on the wiring diagrams supplied with the Enclosed 48
controller. Some factory-set drive parameters are critical for the
Enclosed 48 controller power and control configurations.
• Do not alter the programming of factory-installed control devices or
power contactors.
Failure to follow these instructions can result in death or serious
injury.
For complete information about the operation of the ATS48 soft start, refer
to bulletin S1A37491 and to the drawings supplied with the unit.
Circuit DiagramsThe Enclosed 48 controller is an integrated package that can have different
components and control schemes than those listed in bulletin S1A37491.
Replace the “Recommended Wiring Diagrams” and “Recommended
Components Lists” sections of bulletin S1A37491 with the documentation
shipped with the Enclosed 48 units. Wiring diagrams specific to Enclosed 48
controllers are shipped with each unit. For component information, refer to
the replacement parts list beginning on page 47 of this document, or consult
your Schneider Electric representative.
Integrated Full Voltage
Bypass Starter (MOD A10)
Enclosed 48 controllers can include an optional full-voltage bypass starter
which provides the ability to bypass the ATS48 soft start and run the motor
using across-the-line, full-voltage starting. This mode of operation can be
used when the ATS48 soft start is out of service due to a protective trip
condition but the process needs to continue until a convenient shutdown is
possible. Ensure that the electrical and mechanical systems are compatible
with full-voltage starting before using the bypass starter.
The bypass circuit includes a “Bypass-Norm” (Bypass/Normal) selector
switch mounted on the controller, control logic, and a separate
ambient-temperature compensated bimetallic or solid state overload relay
(SSOLR). When the selector switch is in the Normal position, the ATS48
soft start controls the motor and the bypass contactor functions as a
shorting contactor. The bypass contactor closes when the starting cycle is
complete and opens when a stop command is given.
When the selector switch is in the Bypass position, the ATS48 soft start
does not control the motor. The input contactor and the bypass contactor
are directly opened and closed using a customer-supplied control.
Factory SettingsThe Enclosed 48 controller software is factory configured to match the
power and control options purchased with the enclosed controller.
NOTE: Use caution when making changes to factory configured
parameters. The factory settings are critical for the power and control
options to function properly.
For more information about the Enclosed 48 controller factory settings, refer
to Table 5. A wiring diagram is a part of the “Installation/Maintenance”
packet included with your shipment.
Before powering up the controller for the first time, compare the motor
nameplate current rating with the output current (based on the
horsepower and voltage rating) in Table 7 on page 37. If the motor
nameplate current rating is not within 40 to 100% of the value in the table, a
different ATS48 soft start must be used.

Motor Overload Relay (MOD A10 only)All Enclosed 48 controllers use the solid state thermal overload protection
provided with the Altistart soft start. The bypass starter option provides an
additional ambient-temperature compensated bimetallic overload relay or
SSOLR for supplementary motor overload protection. Check the overload
relay to verify that the current setting matches the actual motor full load
amperes. All adjustable overload relays are factory set for the minimum trip
setting.
Table 8 lists the catalog numbers of the motor overload relays provided with
the MOD A10 option.

Otherwise, the motor can start immediately.
Failure to follow these instructions will result in death or serious
injury.
LOSS OF CONTROL
• The designer of any control scheme must consider the potential failure
modes of control paths and, for certain critical control functions, provide
a means to achieve a safe state during and after a path failure.
Examples of critical control functions are emergency stop and
overtravel stop.
• Separate or redundant control paths must be provided for critical control
functions.
• System control paths may include communication links. Consideration
must be given to the implications of anticipated transmission delays or
failures of the link
• Each implementation of an Enclosed 48 controller must be individually

Power Fuse
Recommendation
The Enclosed 48 controllers are provided with a circuit breaker or with a
fusible switch disconnect.
Units supplied with fusible switch disconnects require the user to supply and
install the power fuses. Select the fuses from Table 9. All of the Enclosed 48
controllers accept UL Class J or L fuses, depending on the full load current
rating.
NOTE: Table 9 replaces the fuse recommendations and references to fuse
type and size listed in bulletin S1A37491. Consult the fuse manufacturer
derating curves before selecting fuses for ambient temperatures above
40 °C (104 °F). Consider that internal ambient temperatures are higher than
external ambient temperatures. For typical wattage values, refer to Table 4
on page 30.
