About the External Shunt Modules
These externally-mounted passive shunt modules provide a means for
servo drives to dissipate excess regenerative energy from the DC bus.
This is needed when system loads require power dissipation beyond
the capability of the shunt resistor internal to the servo drive. These
are passive shunt resistors and require transistor activation by the
servo drive.
A properly-sized shunt module regulates excessive bus voltage by
passing current through a resistor, which dissipates the current as heat
and minimizes drive faults caused by excess bus voltage.

Before You Begin
Before you begin mounting your shunt module, make sure you:
• have the required tools and materials.
• understand the mounting requirements.
• understand high-frequency bonding.
• know how to establish noise zones.
Required Tools and Materials
These tools and materials are required to complete the installation of
an external shunt module:
• Screwdrivers
• User-supplied power wiring
• Mounting fasteners

ATTENTION
Mounting Requirements
Plan the installation of your system so that you can perform all cutting,
drilling, tapping, and welding with the system removed from the
enclosure. Because the system is of the open type construction, be
careful to keep any metal debris from falling into it. Metal debris or
other foreign matter can become lodged in the circuitry, which can
result in damage to components.
These requirements apply when preparing to mount your shunt
module:
• Mo
unt the shunt in an enclosure providing protection against
dust and splashing water (IP54), or dust free and protected
against water jets (IP65).
Many NEMA (National Electrical Manufacturers Association)
ype 4 cabinets provide this level of protection.
T
• Install
the panel for mounting your system components inside
the enclosure on a flat, rigid, vertical surface that won’t be
subjected to shock, vibration, moisture, oil mist, dust, or
corrosive vapors.
Refer to
Environmental Specifications on page 21 for specific
recommendations.
• Maintain minimum clearances for proper airflow, easy module
access, and proper bend radius for the cables as shown in the
figures beginning on page 5
.
• Use high-frequency (HF) bonding techniques to connect the
module, enclosure, machine frame, and motor housing, and to
provide a low-impedance return path for high-frequency (HF)
energy and reduce electrical noise.
Refer to HF Bonding Your Shunt Module, on page 6, for more
information.
Publication 2090-IN004B-EN-P — June 2008
• Se
gregate DC-bus wiring from control wiring and motor
feedback cables. Do not run shunt wiring in wireways. Use
twisted pair cable from the drive to external shunt module.
Refer to
Establishing Noise Zones, beginning on page 6, for
specific recommendations.

The shunt resistors can reach temperatures in excess of 350 °C
(662 °F). Do not handle a shunt module that has been operational until
it has cooled sufficiently.
Combustible materials above the shunt module or its enclosure may
need the protection of a metal plate to shield them from the heat.
Failure to observe these precautions could result in damage to
surrounding materials, possibly leading to a fire or personal injury.
The shunt resistors release large amounts of heat. When mounted
inside an enclosure, you must provide adequate ventilation so the
maximum ambient temperature of 50 °C (122 °F) is not exceeded.
Failure to observe this precaution could result in damage to the
module.

HF Bonding Your Shunt Module
Bonding is the practice of connecting metal chassis, assemblies,
frames, shields, and enclosures to reduce the effects of
electromagnetic interference (EMI). For more information on the
concept of high-frequency (HF) bonding, the ground plane principle,
and electrical noise reduction, refer to System Design for Control of
Electrical Noise Reference Manual, publication
To improve the bond between the drive system and subpanel,
construct your subpanel out of zinc plated (paint-free) steel.

in an externally shielded enclosure. Run shunt DC-bus and fan
wiring inside metal conduit to minimize the effects of EMI and
RFI.
• Mount resistors (other than metal-clad) in a shielded and
ventilated enclosure outside the cabinet.
• Keep unshielded wiring as short as possible. Keep shunt DC-bus
wiring as flat to the cabinet as possible.
• Route thermal switch and fan wires separate from shunt DC-bus.

Follow these steps to wire your external shunt module.
1. Remove power from your drive system that includes the Bulletin
1394 or 2090 shunt module.
This system may have multiple sources of power. More than
one disconnect switch may be required to de-energize the
system. To avoid shock hazard or personal injury, verify that all
power has been removed before proceeding.
This product contains stored energy devices. To avoid hazard
of electrical shock, verify that all voltage on the capacitors has
been discharged before attempting to service, repair, or
remove this unit. You should only attempt the procedures in
this document if you are qualified to do so and familiar with
solid-state control equipment and the safety procedures in
publication NFPA 70E.

IMPORTANT
Wire the Shunt Module Fan
This procedure applies to only the 1394-SR36AF shunt module and
assumes that you have mounted the module and wired the shunt
DC-bus connections.
Refer to Additional Resources on page 22 for the servo drive user
manual with the drive-end installation instructions.
You can wire the shunt fan connections for 115V or 230V AC input
power. Wire should be copper with 75 °C (167 ° F) minimum rating.
Fan Power Specifications
Input Power Current
115V AC 0.2 A
230V AC 0.1 A
If you mount the shunt module outside the cabinet, the shunt fan
power wiring must be inside metal conduit to minimize the levels of
EMI and RFI.

Fuse Holder
Replace the Shunt Module Fuse
Follow these steps to replace the fuse in your external shunt module.
1. Remove power from your drive system that includes the Bulletin
1394 or 2090 shunt module.
This system may have multiple sources of power. More than
one disconnect switch may be required to de-energize the
system. To avoid shock hazard or personal injury, verify that all
power has been removed before proceeding.
This product contains stored energy devices. To avoid hazard
of electrical shock, verify that all voltage on the capacitors has
been discharged before attempting to service, repair, or
remove this unit. You should only attempt the procedures in
this document if you are qualified to do so and familiar with
solid-state control equipment and the safety procedures in
publication NFPA 70E.
2. Open the front door panel and locate the fuse holder.
Publication 2090-IN004B-EN-P — June 2008
In each case, the fuse holder is located in the bottom center of
the shunt enclosure, in some cases, behind terminal blocks.
3. Remove the fuse from the fuse holder.
You may need a fuse puller or screwdriver to remove the fuse.
4. Replace the fuse.
Refer to External Shunt Module Specifications on page 21, for
the properly rated fuse.
5. Close and secure the door panel.
6. Apply power to your system and verify proper operation.

The Bulletin 1394 and 2090 shunt modules ship with fuses
rated for 460V operation. For operation with drive systems
using 230V input power, you must replace the 460V shunt fuse
with a 230V fuse. Failure to observe this precaution could
result in equipment damage.
