Product Description Chapter 1
•Power loss ride-through (TDUV) allows the vacuum contactor to remain
closed during short power loss (may require an optional external capacitor,
dependent on ride-through time).
•Anti-kiss and anti-pumping protection ensure that the vacuum contactor
close – open sequence occurs as expected, avoiding rapid reclosure due to
faulty control devices.
•Delayed restart protects the vacuum contactor by ensuring that the rated
duty cycle is not exceeded.
•Temporary jog function (electrically held contactors only) allows the
motor to be positioned for process set-up.

page 12. They are typically located in the low voltage control panel of the
medium voltage controller (Bulletin 1500/1900 controllers, in the case of
Rockwell Automation).
IntelliVAC is interfaced to the Bulletin 1502 vacuum contactors using a “quick”
connector, located at the module, a wire harness and “quick” connector at the
contactor. Control power and other control circuit connections are similarly
achieved with “quick” connectors.
Configuration
IntelliVACis easily configured for a wide variety of medium voltage motor and
feeder control applications. It is configured using DIP switches, located within
the enclosure (front side). See Chapter 3 for information.
Bulletin 1500/1900 controllers are shipped with IntelliVAC preconfigured for
the required application. Please see the documents provided with the order.
Firmware
IntelliVAChas firmware stored in flash EEPROM. This may be updated in the
field (if necessary). The IntelliVACboard firmware is updated using either the
IntelliVAC Plus, or IntelliVAC MC supplementary boards.
The firmware version supplied with the module is displayed on top of the DIP
switches, see Figure 17 on page 31

Installation and Wiring
General Precautions In addition to the precautions listed throughout this manual, the following
statements, which are general to the system, must be read and understood.
Safety and Codes
Arrangements The IntelliVAC is offered in two arrangements, Integral (part of an Allen-Bradley
Bulletin 1500/1900 MV controller) or as an OEM component.
Integral to an Allen-Bradley MV Controller
The IntelliVAC is available as a primary component of an Allen-Bradley Bulletin
1500/1900 MV controller, see Figure 4 on page 16.
ATTENTION: The controller contains ESD (electrostatic discharge) sensitive
parts and assemblies. Static control precautions are required when installing
testing, servicing, or repairing the assembly. Component damage may result if
ESD control procedures are not followed. If you are not familiar with static
control procedures, see applicable ESD protection handbooks.
ATTENTION: An incorrectly applied or installed controller can damage
components or reduce product life. Wiring or application errors, such as
incorrect or inadequate AC supply, or excessive ambient temperatures, may
result in malfunction of the system.
ATTENTION: Only personnel familiar with the controller and associated
machinery should plan or implement the installation, start-up, and subsequent
maintenance of the system. Failure to do this may result in personal injury and/
or equipment damage.
ATTENTION: The Canadian Electrical Code (CEC), National Electrical Code (NEC),
or other local codes outline provisions for safely installing electrical equipment.
Installation MUST comply with specifications regarding wire type, conductor
sizes, branch circuit protection, interlocking and disconnect devices. Failure to
do so may result in personal injury and/or equipment damage.

(Shown with optional external capacitor)
OEM
The IntelliVAC can be ordered as an OEM component. This allows the OEM to
mount the components in a configuration most suitable to the control
equipment layout. Care must be exercised to ensure the IntelliVAC has adequate
ventilation provided around it. See Figure 5 on page 17 for mounting the
IntelliVAC. It is recommended that a minimum of 38.1 mm (1.5 in.) of free air
space be provided between the IntelliVAC and any solid barrier above or below.
As well, 6.4mm (0.25 in) should be left between adjacent modules.
The OEM is responsible for controller fusing, motor overload protection, control
devices (for example Start/Stop push buttons), and wiring between the
IntelliVAC and 1502 vacuum contactor (using optional wire harness). Wiring and
mounting for optional items, such as TDUV Capacitor, are also the OEM’s
responsibility. See Figure 6 on page 18 for basic connections.

Control Power Fuse
The IntelliVAC module requires external fuse protection to coordinate with the
power supply and contactor. The fuse ratings shown in Tabl e 5 on pa g e 1 9 allow
the passage of inrush currents expected when the contactor is closed, or from
recommended external capacitors for the TDUV option. They will also protect
the contactor coils in the event of a module malfunction.
The recommended fuses have been tested to ensure reliable protection of the
module. If the supply voltage is DC, the module must be used with an external
fuse that is approved for and rated to interrupt the DC voltage supply. The types
listed are Ferraz-Shawmut Midget Fuses (1-1/2 in.X 13/32 in.). The TRM is a
time-delay type, rated 250V AC. The ATM is a fast-acting type, rated 500V DC.

IMPORTANT
If external capacitors are connected, or more than one IntelliVAC module is
protected by a common control fuse, the maximum recommended fuse should
be used to prevent fuse opening due to increased inrush current when control
power is applied.
ATTENTION: It is important that IntelliVAC is properly grounded using the
ground connection provided. Failure to do so may result in damage to
equipment or personal injury.

Control Power
The IntelliVAC can accept either AC or DC control power. See Ta ble 1 o n
page 11 for acceptable input power and control signal ratings.
Control power is applied to the module with a two-pole connector located at the
bottom rear portion of the module. See Figure 7 for connections. The ‘L1’
connection is intended to be the ‘Hot’ or ‘+’ side of the control power, and the
‘L2/N’ connection is intended to be the ‘Neutral’, ‘Return’, or ‘-’ side of the
control power.
Status Relays
Status relay connections are accessed with a four-pole connector located at the
bottom front portion of the module. See Figure 7 for connections. There are two
status relays, each with one normally-open contact:
•Module Status: Terminals 13 and 14
•Contactor Status: Terminals 15 and 16
See Monitoring and Troubleshooting on page 33 for a description of operation
for the relays.
See Ta b le 1 o n pa g e 1 1 for electrical ratings of the status relays.
