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 that dissipates the current as heat and minimizes drive faults.

Before You Begin
Before mounting your shunt module, make sure you do the following:
•
Have the required tools and materials
•
Understand the mounting requirements
•
Understand high-frequency bonding
•
Know how to establish noise zones
For more information on high-frequency bonding and routing of cables within established noise zones, refer to the System Design for Control of Electrical Noise Reference Manual, publication
GMC-RM001 . For the user manual with information specific to your servo drive family, refer to
Additional Resources on page 16
.

4 External Shunt Modules
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
Mounting Requirements
ATTENTION: 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 and result in damage to components.
These requirements apply when preparing to mount your shunt module:
•
Mount 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) Type 4 cabinets provide this level of protection.
•
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 15 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.
•
Segregate 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 Cable Noise Zone Categories
, beginning on
page 6
, for specific recommendations.
IMPORTANT
Mount the shunt module in an upright position. Do not mount the shunt module on its side.

BURN HAZARD: 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.
Shield combustible materials above the shunt module or its enclosure with a metal plate to protect them from the heat.
Failure to observe these precautions could result in damage to surrounding materials, possibly leading to a fire or personal injury.
ATTENTION: 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
GMC-RM001 .
IMPORTANT
To improve the bond between the drive system and subpanel, construct your subpanel out of zinc plated (paint-free) steel.
